Single-feed dual-frequency triangular microstrip antenna with a V-shaped slot

Abstract

Novel design of a dual-frequency triangular microstrip antenna with a V-shaped slot is proposed and experimentally studied. By selecting suitable dimensions of the V-shaped slot, dual-frequency operation with the frequency ratio ranging from 1.488 to 1.834 has been obtained using a single probe feed, and the two operating frequencies are of parallel polarization planes. Typical experimental results of the proposed design are presented and discussed. ©1999 John Wiley & Sons, Inc. Microwave Opt Technol Lett 20: 133–134, 1999.
