    摘要: An antenna comprises an axial helical radiating element and a corrugated ground plane. The axial helical radiating element provides a radiation pattern substantially parallel to a primary axis of rotation of the helical radiating element. The corrugated ground plane, disposed proximate to a back region of the antenna, comprises corrugations to increase an electrical length of travel for radial standing waves between an axial helical input, at which the axial helical radiating element is coupled to the corrugated ground plane, to an outer edge of the corrugated ground plane.

    摘要: A system includes a first antenna and a second antenna. The first antenna includes an antenna section. The antenna section includes a first antenna segment, a second antenna segment adjacent to the first antenna segment, and a notch circuit disposed within a notch between the first antenna segment and the second antenna segment. The notch circuit prevents a first frequency of a signal from passing from the first antenna segment to the second antenna segment while allowing a second frequency from the signal to pass from the first antenna segment to the second antenna segment. The second antenna is disposed proximate to the first antenna. The first antenna occupies a second near field region of the second antenna and the second antenna occupies a first near field region of the first antenna.
