Abstract:
A dual-frequency antenna, comprising:a transmit element that is substantially planar, the transmit element comprising a conductive material having a loaded slot formed therethrough for transmission of first radio frequencies;a receive element that is substantially planar, the receive element comprising a conductive material having a loaded slot formed therethrough for reception of second radio frequencies; anda substrate mounted to the transmit element for transmitting electrical signals to the transmit element from an external device, the substrate comprising:a first conductive region coupled to a region on a first side of the loaded slot of the transmit element; anda second conductive region coupled to a region on a second side of the loaded slot, opposite the first side, of the transmit element;a nonconductive region separating the first conductive region and the second conductive region; anda capacitor electrically coupled between the first conductive region and the second conductive region.
