A practical compact loaded microstrip antenna

A compact loaded microstrip antenna operating at 2.4 GHz is presented in the paper. It is similar in configuration to a conventional patch antenna fed by a microstrip-line, but its dimension is much smaller than that of the latter due to the existence of a load. The antenna has been investigated numerically and experimentally. Simulated and measured, results show that the antenna has a bandwidth of over 10% centered at 2.4 GHz.
