Abstract

Log-periodic slot arrays offer the potential for broadband performance in addition to endfire patterns whose linear polarization is perpendicular to the plane of the array. Effective methods of analyzing such a class of antennas are lacking. In this paper we present a printed microstrip-fed log-periodic slot array featuring a common cavity for all slots. Slot fields and equivalent slot series impedances are determined by a spectral domain moment method. An L band array, with at least an octave of impedance and pattern bandwidth, has been constructed to verify this approach.<>
