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.
