Abstract

A dual‐band dual‐feed planar inverted‐F antenna (PIFA) is tuned with its physical parameters. It is demonstrated that the corner truncation of the patch is less sensitive to the resonant frequency than the patch lengths, but the corner truncation has no adverse effect on the radiation characteristics of the PIFA. This new technique yields quicker convergence of design frequency than the conventional patch length only tuning. Both theoretical and measured results of the input return loss and radiation patterns are presented. © 2001 John Wiley & Sons, Inc. Microwave Opt Technol Lett 31: 345–349, 2001.
