The trace split may feed the first frequency branch and the second frequency branch. The first frequency branch may comprise a first frequency branch geometry that may cause a majority of a current of a signal fed into the trace split to feed the second frequency branch when the signal comprises a second frequency. The second frequency branch may comprise a second frequency branch geometry that may cause the majority of the current of the signal fed into the trace split to feed the first frequency branch when the signal comprises a first frequency.

摘要： An antenna system may include a dual-polarized antenna element having a first dipole and a second dipole in a same lateral plane, the first dipole having a first and a second dipole arm, the second dipole comprising a third and a fourth dipole arm, the first dipole being co-located with the second dipole, and the first dipole having an orthogonal polarization to the second dipole. The antenna system may further include parasitic elements, each comprising at least two branches, the at least two branches including a first branch and a second branch oriented at an angle and forming an apex. A first branch of a first parasitic element may be positioned at a first coupling distance parallel to the first dipole arm of the first dipole, and a second branch may be positioned at a second coupling distance parallel to the third dipole arm of the second dipole.

摘要： A communication system includes an antenna assembly and a housing holding the antenna assembly. The antenna assembly has an antenna element having a substrate and a dual dipole antenna circuit including a low-band ground terminal, a low-band feed terminal, a high-band ground terminal and a high-band feed terminal and a transmission line electrically connected to the dual dipole antenna circuit. The housing includes an upper shell and a lower shell meeting at an interface having upper and lower strain relief components at the interface to receive the transmission line. The upper shell has an upper locating feature and the lower shell has a lower locating feature interfacing to locate the upper shell relative to the lower shell.

摘要： Systems and devices relating to dipole antennas. The beamwidth of a crossed dipole antenna is widened by providing a parasitic monopole antenna adjacent to the crossed dipole antenna. In one configuration, each arm of the crossed dipole antenna has, adjacent to it, a parasitic monopole antenna. In another configuration, the crossed dipole antenna is surrounded by a number of other crossed dipole antennas acting as parasitic monopole antenna elements. The center or primary crossed dipole antenna can be for low band signals while the secondary crossed dipole antennas are for high band signals.

摘要： A printed monopole antenna is disclosed including a printed circuit board having a first side and a second side, a monopole radiating element in the form of a conductive trace formed on one side of the printed circuit board, wherein the conductive trace has an electrical length in which primary resonance occurs within a first specified frequency band, and a parasitic element formed on the opposite side of the printed circuit board, wherein the parasitic element is designed to tune the conductive trace to a secondary resonance within a second specified frequency band. No direct electrical connection between the monopole radiating element and the parasitic element exists, but the coupling between such elements causes the secondary resonance of the radiating element to occur within the second frequency band.
