Compact circular polarized antenna with cavity for additional devices
First Claim
1. An antenna, comprising:
- a plurality of elongated side radiating elements having longitudinal axes oriented at angles of between about 10 and about 80 degrees from a line perpendicular to an imaginary base plane extending across ends of the side radiating elements;
a cavity defined by at least one sidewall, the cavity being positioned between the side radiating elements, the sidewall being non-radio frequency-transparent; and
a plurality of top radiating elements each electrically coupled to an associated one of the side radiating elements, each of the top radiating elements extending in a direction that is not collinear with the longitudinal axis of the associated side radiating element, wherein the at least one sidewall extends at least to an imaginary plane extending through the top radiating elements.

Abstract
According to one embodiment, an antenna comprises a plurality of elongated side radiating elements having longitudinal axes oriented at angles of between about 10° and about 80° from a line perpendicular to an imaginary base plane extending across ends of the side radiating elements, and a cavity positioned between the side radiating elements defined by at least one non-radio frequency-transparent sidewall. In another embodiment, a system comprises a plurality of elongated side radiating elements each lying along a unique side plane and having longitudinal axes oriented at angles of between about 10° and about 80° from a line perpendicular to an imaginary base plane extending across ends of the side radiating elements, and a cavity being positioned between the side radiating elements defined by at least one non-radio frequency-transparent sidewall, wherein the at least one sidewall has sides each lying along a plane about parallel to the unique side plane.
