An apparatus for an antenna assembly, which can be used for a mobile application such as on an aircraft, can include a housing defining an interior. A first antenna, such as a WAAS GPS antenna, can mount within the interior to operate at a first frequency. A second antenna, such as an L-band monopole antenna, can mount within the interior of the housing. A trap coupled to the second antenna can be tuned to the first frequency to prevent signal loss caused by the second antenna.

General aviation dual function antenna

An antenna assembly includes a circularly polarized antenna housing configured to mount to a mounting surface. The antenna assembly also includes a vertical antenna housing having a first end proximate to the circularly polarized antenna housing, as well as a distal end extending normally from the circularly polarized antenna housing.

Wideband, low profile, small area, circular polarized UHF antenna

Wideband, low profile, small area, circular polarized uhf antenna

A collapsible ground plane for a mobile UHF satcom antenna mounted on a riser comprises a hub and a plurality of conductive members, some of which extend radially from the hub with additional conductive members that extend peripherally between adjacent distal ends of the radially extending conductive members. Each conductive member is flexible so as to yield upon an impact, and return to its original shape when the impact is relieved.

Collapsible ground plane for satcom antenna

A UHF satcom antenna comprises a hollow cylinder; an annular substrate disposed on a base of the hollow cylinder; a circular substrate coplanar and concentric to the annular substrate; a plurality of bow-tie antenna elements; a plurality of rectangular antenna elements and a plurality of open-sleeve elements. The antenna system includes at least one feed line extending through the hollow cylinder and the circular substrate and electrically connects to the bow-tie elements. The hollow cylinder may comprise a dielectric material. Provided on the annular substrate, the bow-tie elements extend radially outward from the center of the annular substrate. The rectangular elements are electrically coupled to the plurality of bow-tie antenna elements and are provided on the outer surface of the hollow cylinder. Provided on both the annular substrate and the outer surface of the hollow cylinder, the open-sleeve elements act as parasitic antenna elements for the bow-tie antenna system.
