Abstract :
A dual-frequency antenna consisting of a square microstrip patch with a rectangular notch is experimentally investigated. The resonant frequencies and return loss are shown as a function of the rectangular notch depth. The radiation patterns show that the polarisation planes at the first and second resonant frequencies are perpendicular to each other.
