Edge truncated dual polarised antenna for wireless communication applications

A B ST R A C T Edge truncated slot Aperture microstrip patch antenna for dual frequency operation is investigated in this paper. A simple microstrip edge fed has been used to feed the antenna and a quarter wave length transformers is used for impedance matching. The size of the antenna is reduced by 25.4% when compare to conventional square patch antenna. Design concepts with feeding methods are given along with simulated results. The antenna is showing a gain of 5.9db and a return loss of less than -10dB with VSWR<2 at both resonating frequencies.
