A compact UWB slot antenna optimized by genetic algorithm

A compact ultra‐wideband (UWB) slot antenna based on a mesh‐grid structure is designed. A genetic 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...

description	A compact ultra‐wideband (UWB) slot antenna based on a mesh‐grid structure is designed. A genetic 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 mm × 30 mm and is fabricated and measured. According to the measured results, the proposed antenna yields a wide bandwidth, defined by VSWR
