Abstract
A raised patch antenna is disclosed which includes a base having a ground plane, a plurality of leg supports interconnected to and extending upwardly to the base, a raised patch antenna element supportedly interconnected to the leg supports and positioned over the ground plane and an RF feed comprising a feed-leg portion provided on the leg supports and a feed base portion provided as a part of the base. The RF feed includes impedance matching components for matching the impedance of the feed base portion with the impedance with the raised patch antenna element in series with the feed-leg portion. The feed-leg portion comprises at least a first pair of balanced feed-leg lines interconnected to opposing sides of the raised patch antenna element. Baluns can be provided in said feed base portion for balancing. For circularly polarized applications, a second pair of balance feed-leg lines are interconnected to second opposing sides of the raised patch antenna element for excitation of orthogonal modes, and a phasing means is provided in the feed base portion for achieving phase quadrature. The antenna yields broad overhead coverage and satisfactory bandwidth, and can be economically and readily produced.
