Abstract

A planar-fed reduced size microstrip antenna is presented and discussed. It is demonstrated that, by inserting slots of optimum dimensions into one of the radiating edges of the patch and parallel to the non-radiating edge, size reduction of up to 40% can be achieved. By using this structure, the impedance at the patch edge can be reduced to 50 Ω. This removes the requirement for a impedance matching network and allows the use of a direct planar feed, thus further reducing the total element size.
