ABSTRACT:
The antenna includes a base and a plurality of antenna feeds carried by the base for respective different rotational polarizations. A plurality of inner elongate convex coupler elements are carried by the base and connected to respective ones of the antenna feeds for respective different rotational polarizations, and a plurality of outer elongate convex resonant elements are carried by the base and extend outwardly therefrom a distance greater than the plurality of inner elongate convex coupler elements. The plurality of outer elongate convex resonant elements may be tuned to different resonant frequencies to thereby support the different rotational polarizations. Thus, a small circularly polarized antenna with a hemispherical pattern for high frequency (HF) or satellite applications is achieved.
