PURPOSE: A patch antenna using nonconductive frame is provided to support the resonators without making holes in the resonators and thereby avoids the problem of creating unwanted electric field polarizations and grasp the resonators in areas of low current density and thereby avoids creating additional disturbances in the radiation pattern. CONSTITUTION: Non-conductive frames(124,126) include posts(128). Post holes(129) in feedboard(130) receive posts(128). The frames may be held in place by melting the portion of post(128) that extends through feedboard(130) to form a mushroom cap that holds the frames in place. Resonators(116,118) are snapped into frames(124,126), respectively. The frames hold resonators(116,118) approximately 1/10 of a wavelength at the frequency of operation away from feedboard(130). Front housing section(114) includes tabs(132) that assist in the alignment or placement of feedboard(130) into front housing section(114).
