摘要： Technologies directed to a radio frequency (RF) structure that provides an electrically insulating gap between a ground plane of a circuit board and a chassis at direct current (DC) and an electrical connection between the ground plane and the chassis at RF frequencies. One RF structure includes a first conductor electrically coupled to the ground plane and a second conductor electrically coupled to the chassis. A physical arrangement of a portion of the first conductor and a portion of the second conductor causes the RF structure to provide an electrically insulating gap between the ground plane and the chassis at DC and an electrical connection between the ground plane and the chassis at RF frequencies.

摘要： An antenna apparatus includes an antenna integrated with a filter. The antenna apparatus includes a plurality of resonators where at least some of the resonators are each enclosed in a metal cavity and at least one resonator is exposed to free space to form a radiator element. The antenna apparatus has a filter transfer function that is at least partially determined by dimensions of the radiator element and the position of the radiator element within the antenna apparatus.

摘要： A device for shifting the phase of an electrical signal includes a first microstrip, a second microstrip, and a ground plate. The first microstrip includes an input terminal and the second microstrip includes an output terminal. The second microstrip is spaced apart from the first microstrip such that a microstrip-to-slot transition region is defined between the first microstrip and the second microstrip. The ground plate includes a ground-plate slot that spans the microstrip-to-slot transition region. The ground plate is coupled with the first microstrip and the second microstrip such that at least one of the first microstrip and the second microstrip are movable relative to each other and to the ground plate to adjust a width of the microstrip-to-slot transition region.
