Abstract

We thoroughly investigate the impedance behaviour and scanning potential of microstrip patch antenna arrays consisting of the broadband elements presented in Waterhouse (1998) and Targonski et al. (1998). In particular, a design strategy is developed for these broadband printed antenna arrays. Arrays of probe-fed stacked microstrip patches utilizing high-low dielectric constant material combinations (Waterhouse and Kokotoff 1998) are also investigated. All the arrays presented are analyzed using full-wave spectral domain infinite array analysis.
