Equilateral triangular microstrip antenna for circular polarization dual-band operation

Abstract

Experimental investigations were conducted on the equilateral triangular microstrip antenna to examine the radiation characteristic with two-layer triangular patch antenna. The two-layer triangular patch at both the frequencies 3.0 and 3.5 GHz radiate maximum power, VSWR, return loss, etc, which depended heavily on two-layer triangular microstrip patch antenna. It is shown to be possible to design two-layer equilateral triangular patch antenna for dual-band operation with reasonably good circular polarization.
