An empirical model for the synthesis of microstrip butterfly antenna without ground plane is proposed in this work. A fast design method, properly taking into account the effect of feed connector, is discussed to obtain a compact radiating element (75% reduction with respect to standard patch antenna), with a large bandwidth (about 18%) and an excellent rejection of cross-polar field components. Experimental validations on an UHF butterfly antenna prototype are discussed to show the effectiveness of the approach.

Abstract
An empirical model for the synthesis of microstrip butterfly antenna without ground plane is proposed in this work. A fast design method, properly taking into account the effect of feed connector, is discussed to obtain a compact radiating element (75% reduction with respect to standard patch antenna), with a large bandwidth (about 18%) and an excellent rejection of cross-polar field components. Experimental validations on an UHF butterfly antenna prototype are discussed to show the effectiveness of the approach.File in questo prodotto:
