ABSTRACT: A high-gain wideband low-profile microstrip patch antenna Ngx2N<$<*g  
array is designed and tested. A method for enhancing the impedance 5 `TMqrk  
bandwidth through the combination of a driven rectangular patch KRGj6g+  
with parasitic elements is proposed. The array, which has 16 elements \V'fB5  
in a 4  4 arrangement, is pasted on a 2-mm dielectric substrate. The *[cCY!+Qy  
impedance bandwidth and the gain of the array is 12% (for SWR  2) j8Mt"B  
centered at 4.5 GHz and 20 dBi, respectively. © 2006 Wiley Periodicals, g:RS7od=,
