Abstract
A reconfigurable aperture (Recap) patch antenna with resonant frequencies of 18 GHz and 28 GHz is demonstrated for use in the wideband gapfiller satellite system. The antenna is characterized experimentally with a metal strip representing a closed switch and a gap representing an open switch. The return loss is matched to within 1.5 dB at the two frequencies, consistent with nearly equal resonant impedance. Antenna patterns at 18 GHz show half-power beam-widths (HPBW) of 65° (E-Plane) and 115° (H-Plane) with slight asymmetry. The antenna patterns at 28 GHz show HPBWs of 75° (E-Plane) and 50° (H-Plane). Finite-element method (FEM) computations are performed and compared with experimental results.
