Abstract

A compact ultra-wideband (UWB) slot antenna based on a mesh-grid structure is designed. A Boolean differential evolution (BDE) algorithm is used to optimize the mesh-grid structure as well as other parameters of the proposed antenna for good impedance matching in the UWB band. The optimized UWB antenna has a compact size of 24.2 × 32.2 mm and is fabricated and measured. According to the measured results, the proposed antenna yields a wide bandwidth, defined by S11 < -10 dB ranging from 2.8 to 11.2 GHz. And it shows that the BDE algorithm is an effective method for antenna design.
