Anti-reflective interference antennas with radially-oriented elements
First Claim
1. A radio antenna array for use at a design frequency having reflective interference immunity properties, comprising:
- a rigid planar structure, said structure defining a plane;
a set of directional antenna elements incorporated substantially within said plane, said elements arranged substantially equidistantly from a central point in said plane, said elements further arranged in a radially symmetrical configuration such that the distance between adjacent antenna elements are substantially equal, each of said directional antenna elements having a shape defining a direction of maximal gain;
transmission feed lines electrically connected to said antenna elements;
a combiner positioned substantially at said central point and further electrically connected to said antenna elements through said transmission feed lines, said combiner further providing a point of electrical connection for radio electronics;
whereby each of said directional antenna elements is oriented at the same angle with respect to said central point.

Abstract
Disclosed herein are wireless products adapted to be positioned in a normal or resting position, that also include an antenna composed of a set of elements arranged in a plane in a radially symmetrical configuration providing a reduction in the susceptibility of reflected waves having the potential to cancel or weaken a main wave or signal, the plane positioned with respect to the normal position to direct a main communication line with a second wireless device into the plane and provide reception of a main and/or secondary signal at a plurality of phases. One exemplary product is a wireless conferencing device configured to rest on a tabletop, the antenna array oriented in a horizontal plane. Detailed information on various example embodiments of the inventions are provided in the Detailed Description below, and the inventions are defined by the appended claims.
