COUPLED-FED CIRCULAR PATCH ANTENNA
 
     
 
Structure on IE3D

Parameters:

No.1 and No.2 substrate thickness = 0.159 mm, permittivity = 2.62

Circular patch is on the No.2 substrate, and feed line is on the No.1 substrate. Circular patch diameter is 35 mm. Feed line width is 4.373 mm. The feed line ends at the center of the circular patch and the feed line is 79 mm long.

Simulation Result:

The structure and measured data are from M. Davidovitzand Y. T. Lo, "Rigorous analysis of a circular patch antenna excited by a microstrip transmission line". IEEE Trans. Antennas Propagat.,Vol, AP-37, Aug. 1989, pp. 949-958.
