Abstract
The antenna assembly is circularly polarized and may be able to receive multiple independent signals. The antenna assembly includes a plurality of electrically conductive layers arranged about an axis to define a series of adjacent corner reflectors (e.g. four to eight corner reflectors), and a plurality of spiral antenna elements. Each spiral antenna element extends across a respective open end of a corresponding corner reflector. Each corner reflector may have an equal corner angle, and each spiral antenna element may be a bifilar spiral antenna element and/or a log spiral antenna element. A housing may contain the corner reflectors and the spiral antenna elements. Electronic circuitry may be coupled to the plurality of spiral antenna elements and contained within the housing. The antenna is preferential for television reception on multiple channels and directions without consumer adjustment, as the antenna provides spatial, angular and frequency diversity through simultaneous overlapping beams.
