Input impedance and mutual coupling of probe-fed cylindrical-circular microstrip patch antennas

Abstract

The input impedance and mutual coupling of cylindrical-circular microstrip patch antennas in the TM11 mode are experimentally studied. Measured results for the antennas on curved surfaces of different cylinder radii are presented, and the curvature effects on the input impedance and mutual coupling are analyzed. Theoretical formulation with the use of the generalized transmission-line model (GTLM) theory are also described, and the calculated results are shown for comparison with the measured data. © 1996 John Wiley & Sons, Inc.
