Experimental Studies of a Shorted Triangular Microstrip Antenna Embedded With Dual V-shaped Slots

Abstract

The design of an equilateral triangular microstrip antenna embedded with dual V-shaped slots and two shorting walls is proposed and experimentally studied. By properly selecting suitable dimensions for this microstrip antenna, dual frequency operated at TM₁₁ and TM₂₁ modes, with frequency ratio ranging from 1.28 to 1.5 can be achieved with a single probe feed. The experimental procedures on achieving such operation with a maximum gain of around 11 dBi are presented and discussed.
