Abstract:
A system such as a vehicle may have windows. A window may have a structural window layer formed from one or more glass layers. A conductive coating such as an infrared-light blocking coating or other optical filter layer may be formed on the window. The conductive coating may include one or more silver layers or other conductive material. Unpatterned portions of the conductive coating are conductive along orthogonal dimensions. A region of the conductive coating may have parallel line-shaped openings that render the coating conductive in only a single dimension while enhancing radio transparency. Another region of the conductive coating may have a two-dimensional pattern of openings such as a mesh-shaped opening formed from intersecting straight and/or curved lines. In this region, the coating is locally rendered insulating and radio-frequency transparent. Antennas and ohmic heating elements may be formed in the coating.

     FIELD 
     This relates generally to windows, and, more particularly, to coated windows. 
     BACKGROUND 
     Windows such as vehicle windows are formed from glass. To provide desired functions such as defogging and wireless communications, conductive structures such as metal wires and films are sometimes incorporated into windows. These structures can be unsightly or can block radio-frequency signals associated with wireless devices being operated in the interior of a vehicle. 
     SUMMARY 
     A system such as a vehicle may have windows. A window may have a structural portion formed from one or more transparent structural layers. The structural layers may be formed from glass. In windows with multiple glass layers, the glass layers may be laminated together with a layer of polymer. 
     A conductive coating may be formed on the window. The conductive coating may include one or more silver layers or one or more layers of other conductive material. The conductive coating may form an infrared-light-blocking filter or other optical filter and/or may form a low-emissivity layer that blocks heat. 
     Unpatterned portions of the conductive coating have low sheet resistance and are conductive in multiple orthogonal dimensions (e.g., horizontally and vertically). A region of the conductive coating may have parallel line-shaped openings (insulating lines) that render the coating conductive in only a single dimension while enhancing radio transparency. Another region of the conductive coating may have a two-dimensional pattern of openings such as a rectangular grid of openings formed from intersecting horizontal and vertical insulating lines or an insulating grid formed from openings of other shapes (circular, hexagonal, triangular, etc.). In this region, the coating is locally rendered insulating and radio-frequency transparent. Antennas and ohmic heating elements may be formed in the coating.

     DETAILED DESCRIPTION 
     A system may have windows that include components formed from a patterned conductive layer. The patterned conductive layer may be a layer associated with blocking near infrared light and/or blocking heat or any other suitable conductive window layer. The components formed from the patterned conductive layer may include antennas and may include ohmic heaters for defogging the windows. The system may be a building, a vehicle, or other suitable system. Illustrative configurations in which the system with the windows is a vehicle may sometimes be described herein as an example. This is merely illustrative. Window structures with patterned conductive layers may be formed in any suitable system. 
     An illustrative system of the type that may include windows with a patterned conductive layer is shown in  FIG. 1 . As shown in  FIG. 1 , system  10  may be a vehicle having a body such as body  12  with a chassis to which wheels are mounted, propulsion and steering systems, and other vehicle systems. Body  12  may include doors, trunk structures, a hood, side body panels, a roof, and/or other body structures. Seats may be formed in the interior of body  12 . Vehicle  10  may include windows such as window(s)  16 . Window  16  and portions of body  12  may separate the interior of vehicle  10  from the exterior environment that is surrounding vehicle  10 . 
     Windows  16  may include a front window  16  on front F of vehicle  10 , a moon roof (sun roof) window  16  or other window extending over some or all of top T of vehicle  10 , a rear window  16  on rear R of vehicle  10 , and side windows on the sides of vehicle  10  between front F and rear R. 
     An illustrative configuration for a window such as one of windows  16  of  FIG. 1  is shown in  FIG. 2 . Window  16  may one or more structural layers. In some arrangements, window  16  may include only a single structural layer (e.g., a layer of glass having a thickness of 3-6 mm or other suitable thickness for providing window  16  with sufficient structural support to allow window  16  to be used in a vehicle). In the example of  FIG. 2 , window  16  includes two structural window layers  16 M, one of which faces window exterior  80  and one of which faces window interior  82 . Layers  16 M may be formed from transparent glass, transparent plastic, or other structural window materials. These layers may be strengthened (e.g., by annealing, tempering, and/or chemical strengthening). Each of layers  16 M may be, for example, 1.6 to 3.2 mm thick, at least 1.5 mm thick, less than 4 mm thick, or other suitable thickness. 
     Layers  16 M may be laminated to each other using polymer layer  84  (e.g., to form a laminated window). Polymer layer  84  may be, for example, a polymer such as polyvinyl butyral (PVB) or ethylene-vinyl acetate (EVA). Polymer layer  84  may have a thickness of 0.76 mm or other suitable thickness (e.g., greater than or less than 0.76 mm). If desired, a thinner polymer layer (e.g., a layer of 0.38 mm) may be used in a configuration of the type in which window  16  includes a stiff interlayer (e.g., a polyethylene terephthalate layer). In general, any suitable thickness may be used for layer  30  (e.g., at least 0.3 mm, less than 0.8 mm, etc.) 
     As shown in  FIG. 2 , window  16  may include a coating layer such as coating layer  30 . Coating layer  30  may include one or more sublayers and may be used to provide infrared-light blocking, low-emissivity (heat-blocking), and/or other desired properties to window  16 . As an example, layer  30  may be an infrared-light blocking layer and/or low-emissivity layer having one or more silver layers  86  and one or more metal oxide layers (e.g., tin oxide, zinc oxide, etc.), other inorganic dielectric layers (e.g., silicon oxide, silicon nitride, etc.) or other dielectric layers  88 . Layer  30  may be configured to serve as a low-emissivity (“low-e”) layer that blocks heat and/or may serve as an optical filter layer that reduces infrared light transmission (e.g., layer  30  may reduce transmission of solar infrared light at wavelengths of about 0.7 microns to 2.5 microns to less than 50%, less than 10%, etc. while transmitting visible light (e.g., transmitting at least 70% of visible light or at least transmitting more visible light than infrared light, etc.). Coating layer  30  may include one silver layer, two silver layers, three silver layers (triple silver), four layers of silver (quad silver), or other suitable infrared-light-blocking coating materials. By blocking infrared light, vehicle occupant comfort may be enhanced. If desired, other types of optical filter layer may be formed from coating layer  30  (e.g., tinting, neutral density filtering, etc.). Coatings such as coating layer  30  may be formed on the inner surface of the outer glass layer  16 M and/or other surfaces of layer(s)  16 M. Because coating layer  30  includes one or more conductive material layers (e.g., one or more silver layers  86 ), coating layer  30  may sometimes be referred to as a conductive coating layer, conductive coating, or conductive layer. 
     Laser patterning, lift-off techniques, and/or other conductive layer patterning techniques may be used in forming a pattern of openings in layer  30 . As shown in  FIG. 3 , for example, openings such as opening  32  may be formed in layer  30 . Opening  32  does not contain conductive material and is therefore insulating. Opening  32  may be filled with a dielectric such as air or may, if desired, be filled with a solid dielectric such as dielectric  90  (e.g., transparent polymer or other inorganic and/or organic dielectric). The incorporation of polymer 90 or other transparent material into opening  32  may visually blend opening  32  with surrounding window structures. In this way, a pattern of openings  32  (e.g., parallel lines, grid-shaped lines, etc.) may be unnoticeable to a viewer. 
     Different regions of conductive layer  30  may be provided with openings  32  of different patterns. Consider, as an example, the illustrative portion of window  16  of  FIG. 4 . In this example, window  16  lies in the X-Y plane. 
     In region  16 A, conductive layer  30  is unpatterned (free of openings  32 ) and is therefore conductive along both the X and Y dimensions. 
     In region  16 B, conductive layer  30  has a set of parallel line-shaped openings  32 . These openings may be, for example, about 10-30 microns in width, at least 5 microns in width, less than 40 microns in width, less than 30 microns in width, less than 20 microns in width, or other suitable size. The use of small dimensions for openings  32  may help prevent openings  32  from being visible to a viewer. The opening  32  in region  16 B form insulating (electrically isolating) lines that run parallel to the X dimension. The insulating lines formed by openings  32  in region  16 B may be spaced apart by a distance of about 0.1-10 mm, at least 0.5 mm, at least 0.7 mm, less than 5 mm, less than 2.5 mm, less than 1.2 mm, or other suitable spacing. Due to the presence of horizontal insulating lines  32  in region  16 B, coating  30  is conductive along a single dimension. In particular, coating  30  in region  16 B is conductive along dimension X (current can be conducted horizontally), but is electrically insulating (and therefore exhibits a high resistivity and low conductivity) along the Y dimension. The insulating nature of region  16 B in the Y dimension may enhance radio-frequency transparency of window  16  (e.g., light that is polarized parallel to the Y dimension may pass through region  16 B without being significantly attenuated). This allows cellular telephones, computers with wireless communications circuitry, and other wireless electronic devices in the interior of a vehicle or other system to be used to transmit and receive wireless signals. 
     In region  16 C, conductive layer  30  has openings  32  formed in a two-dimensional pattern that prevents current from flowing either horizontally (in the X dimension) or vertically (in the Y dimension). In the example of  FIG. 4 , openings  32  have a grid-shaped pattern formed from intersecting horizontal and vertical insulating lines, but other patterns of openings may be formed to restrict current flow in both horizontal and vertical dimensions, if desired. Due to the patterning of openings  32  in conductive layer  30  in region  16 C, region  16 C is rendered insulating (e.g., the portion of conductive layer  30  in region  16 C is no longer macroscopically conductive). The insulating portion of coating layer  30  that is formed in region  16 C will exhibit radio transparency. For example, region  16 C will be radio transparent to radio-frequency signals polarized along either the X or Y dimension. Radio-frequency signals for an electronic device in the interior of system  10  can be received through region  16 C and radio-frequency signals being transmitted by an electronic device in the interior of system  10  may pass through region  16 C to the exterior of system  10 . Patterning a portion of coating  30  using a two-dimensional grid pattern or other pattern of the type shown in region  16 C of  FIG. 4  will therefore selectively render that portion of coating  30  insulating (e.g., resistivity and sheet resistance in two orthogonal horizontal dimensions will be high and conductivity will be low). 
     By patterning conductive layer  30  to contain regions  16 A,  16 B, and/or  16 C of desired shapes, conductive layer  30  may be configured to form regions that are suitable for forming thin-film ohmic heating elements and that are suitable for forming antennas. Ohmic heating elements may be used to form defogging heaters in one or more portions of window  16 . Antennas can be used to transmit and/or receive wireless signals. 
       FIG. 5  is a circuit diagram of illustrative circuitry that may be used in system  10  to form a heater and a wireless communications circuit. As shown in  FIG. 5 , coating  30  may be patterned to form one or more antennas such as antenna  62 . Coating  30  may also be patterned to form ohmic heating elements such as ohmic heating element  66 . The portions of conductive coating  30  that are used in forming heating element  66  may be shared with the portions of conductive coating  30  that are used in forming antenna  62  and/or may be partially or fully separate from the portions of conductive coating  30  that are used in forming antenna  62 . 
     Radio-frequency transceiver circuitry  50  may be coupled to antenna  62  using transmission line structures such as transmission line  52 . Transmission line  52  may have positive and ground signal lines  54  coupled to respective antenna feed terminals  56  of antenna  62 . If desired, impedance matching circuitry and/or antenna tuning circuitry may be incorporated into antenna  62  and/or interposed into transmission line  52  to adjust the performance of antenna  62 . Capacitors C may, if desired, form high-pass filters that are used to block low-frequency noise (e.g., by preventing direct-current signals at 0 Hz and other low-frequency signals from passing between antenna  62  and transceiver circuitry  50 ) while allowing radio-frequency signals from transceiver circuitry  50  to be transmitted to antenna  62  and to be received from antenna  62 . Transceiver circuitry  50  may include wireless local area network transceiver circuitry operating at 2.4-5 GHz, may include cellular telephone circuitry operating at 700 MHz-2700 MHz, less than 700 MHz, more than 2700 MHz, and/or other suitable cellular telephone frequencies, may include satellite navigation system circuitry operating at 1575 MHz and/or other satellite navigation system frequencies, and/or may include other wireless circuitry (e.g., near-field communications circuitry, millimeter wave circuitry, circuitry operating in bands below 700 MHz, circuitry operating in bands above 2700 MHz, etc.). Transceiver circuitry  50  may include radio receiver circuitry (e.g., amplitude modulation radio circuitry, frequency modulation radio circuitry, satellite radio circuitry, etc.), may include television receiver circuitry for receiving terrestrial and/or satellite television broadcasts, and/or may include other wireless transceiver circuitry. Heater controller  68  may include circuitry for producing signals that are applied to a thin-film heating element  66  formed from patterned coating layer  30 . Inductors L may be interposed between heater controller  68  and heating element terminals  70 . Inductors L may form low-pass filters that allow low-frequency signals from heating controller  68  (e.g., direct-current signals, low-frequency pulse-width-modulated signals or other pulsed signals such as signals at 1-10 Hz, at least 1 Hz, less than 100 Hz, or other low frequencies, etc.) to be applied to heating element  66  while blocking radio-frequency signals that have been coupled into element  66  from transceiver circuitry  50 . 
       FIGS. 6, 7, 8, 9, 10, and 11  are top views of portions of coating layer  30  that have been patterned using different illustrative patterns of openings  32 . In  FIG. 6 , openings  32  form a grid of vertical and horizontal lines. In  FIG. 7 , openings  32  form a grid that divides layer  30  into triangular islands. In  FIG. 8 , openings  32  have the shape of hexagons. Circular openings  32  of  FIG. 9  are arranged in a rectangular array. Circular openings  32  of  FIG. 10  are arranged in an array in which alternating rows of circles are offset from each other. The linewidth b of the grid-shaped openings  32  of  FIGS. 6, 7, 8, 9, and 10  may be about 1-100 microns, 10-30 microns, at least 5 microns, less than 40 microns, less than 30 microns, less than 20 microns, less than 100 microns, or other suitable size to help visually hide openings  32 . The resulting characteristic lateral dimension a of the islands of conductive material  30  that are produced by forming openings  32  may be about 0.1-10 mm, at least 0.5 mm, at least 0.7 mm, less than 5 mm, less than 2 mm, less than 1.2 mm, or other suitable size. Different sizes for parameters a and b may be selected depending on the operating frequency of radio-frequency transceiver  50 . As an example, if transceiver  50  operates in a 5 GHz communications band, a may be 1 mm and b may be 20 microns. 
     The two-dimensional patterning of openings  32  in these illustrative patterns serves to form an electrically insulating and radio-transparent region  16 C in coating  30 , as described in connection with  FIG. 4 . If desired, parallel insulating lines (see, e.g., openings  32  of  FIG. 11 ) may be formed in coating  30  (e.g., to form a region that is electrically conductive in one lateral dimension but not the other and that is radio-transparent for signals with at least one linear polarization). Line-shaped openings may be oriented horizontally, vertical, diagonally, etc. In some arrangements, different areas of window  16  may have lines with different orientations (e.g., vertical lines in one section of window  16  and horizontal lines in another section of window  16  to ensure that window  16  has regions that are radio-transparent to radio-frequency signals with different polarizations). When lines  32  run horizontally, coating  30  is rendered insulating in the vertical direction and may pass radio-frequency signals that are linearly polarized vertically. When lines  32  run vertically, coating  30  is rendered insulating in the horizontal direction and may be transparent to radio-frequency signals that are linearly polarized along the horizontal dimension (while blocking vertically polarized signals). In some arrangements, diagonal lines  32  may partially block and may partially transmit both horizontally polarized and vertically polarized signals. 
       FIG. 12  is a diagram of an illustrative window containing a patterned conductive coating that forms two antennas (slot antenna  62 A and inverted-F antenna  62 B) and that forms a thin-film ohmic heating element such as heating element  66 . Heating element  66  may be formed from a region of coating  30  that has been patterned using the pattern of region  16 B of  FIG. 4  (or, if desired, a portion of a region without openings such as region  16 A). When heating element  66  is formed in region  16 B, current applied to heating element  66  by heater controller  68  using heater terminals  70  is allowed to flow horizontally and heats heating element  66  by ohmic heating. Because region  16 B is at least partially conductive, coating  30  in region  16 B may also serve as a ground plane for radio-frequency antenna signals. The ground plane may be provided with an insulating region  16 C by patterning coating layer  30  within a slot-shaped portion of region  16 B, as shown in  FIG. 12 . The slot-shaped insulating region  16 C in the ground plane formed from region  16 B can be used in forming slot antenna  62 A. Antenna feed terminals  56 A may be used in feeding antenna  62 A. Inverted-F antenna  62 B, which may be fed using antenna feed terminals  56 B, may be formed by patterning an F-shaped inverted-F resonating element from coating  30  (e.g., by forming an unpatterned region  16 A of coating  30  within a surrounding insulating region  16 C of coating  30 ). If desired, other antenna types may be formed (e.g., other planar antennas such as monopoles, dipoles, loop antennas, patch antennas, bowtie antennas, etc.). The illustrative slot and inverted-F antennas of  FIG. 12  are merely illustrative. 
       FIG. 13  is a top view of the feed portion of illustrative slot antenna  62 A of  FIG. 12 . In the example of  FIG. 13 , feed terminal  56 A 1  is coupled to a portion of the ground plane (formed from conductive area  16 A of coating  30 . Antenna  62 A is feed on an opposing side of the antenna slot formed from insulating region  16 C by an overlapping portion of conductive strip  96  forming antenna feed terminal  56 A 2 . Transmission line conductors (see, e.g., lines  54  of  FIG. 5 ) may be coupled to feed terminal locations  56 A 1  and  56 A 2 ′ of  FIG. 13  (as an example). A cross-sectional side view of the portion of antenna  62 A shown in  FIG. 13  is shown in  FIG. 14 . Layers  96  and  102  may be silver layers  88  of  FIG. 2  or other conductive sublayers in coating  30  or other coatings on window  16 . In region TL, a portion of layer  96  may form a first transmission line conductor  54  and a portion of layer  102  may form a second transmission line conductor  54 . Dielectric  104  (see, e.g., dielectric layers  88  of  FIG. 2 ) may separate conductors  54 . Feed terminal  56 A 1  may be coupled to the second transmission line conductor. Feed terminal portion  56 A 2 ′ may be coupled to the first transmission line conductor. In region  56 A 2 , a strip-shaped portion of layer  96 , which is coupled to terminal portion  56 A 2 ′, may be capacitively coupled to an overlapped portion of conductive layer  102  (which has been patterned to form a conductive ground plane region  16 B) and may therefore form a feed terminal for antenna  62 A. 
     If desired, regions of coating  30  such as multiple areas of region  16 B may be provided with separate sets of heater terminals. As shown in  FIG. 15 , for example, region  16 B may have a first set of heater terminals  70 A, a second set of heater terminals  70 B, and a third set of heater terminals  70 C. Each pair of heater terminals in this example can be individually adjusted using a respective heater controller (see, e.g., heater controller  68  of  FIG. 5 , allowing different areas of window  16  to be selectively defogged.). To allow current to flow between the first and second terminals in each pair of terminals, line-shaped openings  32  in coating layer  30  of region  16 B of  FIG. 15  may run horizontally. 
     The foregoing is merely illustrative and various modifications can be made to the described embodiments. The foregoing embodiments may be implemented individually or in any combination.
