A dual band circularly polarized microstrip antenna on an EBG substrate
IEEE Antennas and Propagation Society International Symposium (IEEE Cat. No.02CH37313)
A novel circularly polarized (CP), single-fed microstrip antenna on an electromagnetic band gap substrate (EBG) is presented. The antenna consists of stacked structure of almost square patches and an EBG substrate for the lower patch. The proposeddesign has a reduced antenna size= compared to theconventional C P microstrip antenna at a given oprating frequency and of lightweight. The impedance and axial ratio bandwidths are large and C P rad ation quality is excellent over the entire upperdoi:10.1109/aps.2002.1016030 fatcat:gjsmpzbk6newpkjht7qbg5imz4
