PRINTED COMPACT LENS ANTENNA FOR UHF BAND APPLICATIONS

By K. K. Ajith and A. Bhattacharya

Full Article PDF (667 KB)

Abstract:
A new microwave lens antenna suitable for ultra-high frequency (UHF: 300 MHz-3 GHz) band applications is proposed. An improved bow-tie antenna and a planar metamaterial lens design is presented. 5 dB improvement in boresight gain and a directive radiation pattern is achieved with the lens. The application of the designed antenna is demonstrated in a ground penetrating radar (GPR) experiment. The size of the antenna is very compact compared to other antennas found in the literature used for similar applications.
