Abstract
An E-shaped patch antenna fed by a folded L-shaped probe is proposed. The shorted wall loading is employed to make the antenna compact, and the lateral size is only 0.196 lambdaL times 0.221 lambdaL, where lambdaL is wavelength at the lower cutoff frequency of the measured operating bandwidth in the free space. Three adjacent resonances are utilized to achieve a broad band while keeping the antenna very low profile. The air substrate is only 4 mm (i.e., 0.029 lambdaL) thick, and the measured impedance bandwidth is about 19.8% (with a central frequency of 2.378 GHz). The procedure of optimal design is also described.Keywords
