Abstract: A dual-band antenna array may be provided. The dual-band antenna array may comprise a trace split, a first frequency branch, and a second frequency branch. 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.

Abstract: A microwave antenna assembly is printed on a substrate with a first face and an opposing second face. The assembly includes at least one antenna disposed on the front face of the substrate and a balun disposed on the rear face of the substrate. A first microstrip on the front face is coupled to the antenna(s). A second microstrip on the front face is coupled a feed line. A coplanar strip on the rear face is electrically coupled to the second microstrip and electromagnetically coupled to the first microstrip.

Abstract: Embodiments disclosed herein generally relate to a dipole antenna having an hourglass shaped coupler. The antenna generally includes two conductive layers, each having a first portion and a second portion of conductive material. The first portion may be connected to a first trace in the first layer, and a width of the first portion flares out from a connection point to the first trace in a first direction. The second portion may be electrically isolated from the first trace and a width of the second portion flares out from a location closest to the first portion in a second direction. In certain embodiments, the second direction is opposite the first direction.

CPC classification number: H04W16/28
Abstract: In one implementation, a device includes a first set of antennas having a first polarization; and a first radio coupled to the first set of antennas, the combination of the first set of antennas and the first radio supporting a first signal. The device also includes: a second set of antennas having a second polarization, the second polarization is different from the first polarization; and a second radio coupled to the second set of antennas, the combination of the second set of one or more antennas and the second radio supporting a second signal, the second signal is independent of the first signal. In some implementations, the first radio is operated according to a first power level in order to establish the first coverage area, and the second radio is operated according to a second power level in order to establish the second coverage area.
