## Background
TECHNICAL FIELD
The present disclosure relates generally to the design of communications equipment modules.
BACKGROUND
An antenna (or aerial) is an electrical device which converts electric power into radio waves, and vice versa. It is usually used with a radio transmitter or radio receiver. In transmission, a radio transmitter supplies an oscillating radio frequency electric current to the antenna's terminals, and the antenna radiates the energy from the current as electromagnetic waves (radio waves). In reception, an antenna intercepts some of the power of an electromagnetic wave in order to produce a tiny voltage at its terminals that is applied to a receiver to be amplified.
Antennas are essential components of all equipment that uses radio. They are used in systems such as radio broadcasting, broadcast television, two-way radio, communications receivers, radar, cell phones, and satellite communications, as well as other devices such as garage door openers, wireless microphones, bluetooth enabled devices, wireless computer networks, baby monitors, and RFID tags on merchandise.
Typically an antenna consists of an arrangement of metallic conductors (“elements”), electrically connected (often through a transmission line) to the receiver or transmitter. An oscillating current of electrons forced through the antenna by a transmitter will create an oscillating magnetic field around the antenna elements, while the charge of the electrons also creates an oscillating electric field along the elements. These time-varying fields, when created in the proper proportions, radiate away from the antenna into space as a moving transverse electromagnetic field wave. Conversely, during reception, the oscillating electric and magnetic fields of an incoming radio wave exert force on the electrons in the antenna elements, causing them to move back and forth, creating oscillating currents in the antenna.
An antenna faceplate for a communication module may be provided. Conventional faceplates for rack-insertable communication modules comprise a vertical surface to which additional equipment, such as antennas are mounted. However, these arrangements fail to dissipate enough heat to satisfy some manufacturer's specifications. Furthermore, the flat panel design results in attachments that interfere with the cabling to and from other modules.

DETAILED DESCRIPTION
Overview
Consistent with embodiments of the present disclosure, systems and methods are disclosed for user terminal location.
A faceplate configured for attachment to a communications module may be provided. The faceplate may comprise a first surface arranged in a vertical direction relative to the chassis and a second surface arranged at an angle to the first surface. The second surface may comprise a connector for attachment to another piece of equipment, such as an antenna.
It is to be understood that both the foregoing general description and the following detailed description are examples and explanatory only, and should not be considered to restrict the disclosure's scope, as described and claimed. Further, features and/or variations may be provided in addition to those set forth herein. For example, embodiments of the disclosure may be directed to various feature combinations and sub-combinations described in the detailed description.
Example Embodiments
The following detailed description refers to the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and the following description to refer to the same or similar elements. While embodiments of the disclosure may be described, modifications, adaptations, and other implementations are possible. For example, substitutions, additions, or modifications may be made to the elements illustrated in the drawings, and the methods described herein may be modified by substituting, reordering, or adding stages to the disclosed methods. Accordingly, the following detailed description does not limit the disclosure. Instead, the proper scope of the disclosure is defined by the appended claims.
Embodiments of the disclosure may comprise a faceplate. The faceplate may operate, for example, in the smart grid environment (e.g. −40 C to 85 C). A fan may not be allowed for cooling. Consequently, heat may be dissipated, for example, through an external surface that may be a front panel. The front panel may not include enough surface area and may further be covered by other antenna connectors. Conventional flat panel design failed to dissipate sufficient amounts of heat.
Embodiments of the disclosure may include connectors for antennas mount on, for example, a 30 degree faceplate. Installed antennas positioned with 30 degree angle from the faceplate may avoid interfering with cablings from other rack units. This angled faceplate design may resolve the cooling and antenna interference issues while keeping the overall depth the same as conventional panel designs, for example.
FIG. 1 is a front elevation view of an antenna faceplate 100. Antenna faceplate 100 may comprise a plurality of connection points 110(A)-(C) for mounting to a chassis, such as a rack-mountable equipment chassis 500, discussed in more detail below with respect to FIG. 5. Antenna faceplate 100 may comprise a first surface 120, a second surface 130, and a third surface 140. First surface 120 and third surface 140 may be arranged such that they are vertically oriented and substantially parallel to each other. Second surface 130 may be situated at an angle relative to first surface 120 and third surface 140. Each surface 120, 130, and 140 may be configured to provide one and/or more connection point(s) to additional pieces of equipment, such as an accessory connector 150 on first surface 120 and a plurality of primary connectors 160(A)-(B) on second surface 130. Antenna faceplate 100 may also comprise additional features such as a plurality of indicator lights 170(A)-(D) and/or a plurality of vent holes 180(A)-(C). Antenna faceplate 100 may be fabricated from a material selected for its heat dissipation properties, such as aluminum.
FIG. 2 is a side elevation view of antenna faceplate 100 illustrating the angle of second surface 130 relative to first surface 120 and third surface 140. In this illustration, second surface 130 is arranged at 30° relative to a horizontal plane perpendicular to the vertical orientation of first surface 120 and third surface 140. This angle may vary, and may be selected according to various factors. These factors may comprise minimizing interference between primary connectors 160(A)-(B) and accessory connector 150 and/or minimizing interference between any attachments to any connectors on any of surfaces 120, 130, and 140. Further, the design of the vertical and angled surfaces may operate to extend a heat dissipation area for the module, improving the thermal characteristics over the limited efficiency of an internal heat sink (not shown). The internal heat sink may be attached to the front surface so that heat is conducted from heat sources inside the module through the heat sink and to the faceplate for dissipation into the environment. The depth of third surface 140 may be selected to match the depth of primary connectors 160(A)-(B) as if they were mounted on first surface 120. For example, in the example illustrated by FIG. 2, the depth of third surface 140 is approximately 0.9′′, which is approximately equivalent to the exposed length of a threaded Neill-Concelman (TNC) connector when mounted horizontally.
FIG. 3 is an auxiliary view of antenna faceplate 100 coupled to a communications module 300. Communications module 300 may comprise equipment such as a printed circuit board (PCB) 310, a heat sink 320, and a connector 330 for communicatively coupling to rack-mountable equipment chassis 500.
FIG. 4 is a second auxiliary view of antenna faceplate 100 and communications module 300 with an attached pair of antennas 410(A)-(B). In this example, primary connectors 160(A)-(B) comprise TNC connectors coupled to LTE antennas.
FIG. 5 is an auxiliary view of communications module 300 coupled to rack-mountable equipment chassis 500 with antenna faceplate 100 exposed.
Consistent with embodiments of the disclosure, an apparatus may be provided. The apparatus may comprise a faceplate configured for attachment to a communications module. The faceplate may comprise a first surface arranged in a vertical direction relative to the chassis and a second surface arranged at an angle to the first surface.
Consistent with other embodiments of the disclosure, an apparatus may be provided. The apparatus may comprise a faceplate configured for attachment to a chassis. The faceplate may comprise a first vertical surface, a second vertical surface, and a third surface arranged at an angle between the first vertical surface and the second vertical surface.
Consistent with yet other embodiments of the disclosure, an apparatus may be provided. The apparatus may comprise a faceplate for a communications module. The faceplate may comprise a first surface arranged at a non-vertical angle from a horizontal plane. The first surface may comprise at least one antenna connector.
