Abstract :
An experimental investigation of a 16*16 microstrip array of rectangular patch radiating elements is reported. Results for the radiation characteristics and impedance bandwidth of the array with and without stacked parasitic elements are presented. The measured impedance bandwidth of the array with stacked parasitic elements is more than twice as broad as the bandwidth of the array with single patch elements, and is about twice that of a single stacked parasitic patch antenna.<>
