A Wideband Directional mm-Wave Antenna for Micro-Deformation Monitoring Radar Applications

A wideband mm-wave antenna is proposed with a directional radiation pattern for micro-deformation monitoring radar applications. The devised antenna consists of a coplanar waveguide (CPW) feeding, a dipole-like radiating patch, a parasitic strip setting at the front of the radiating patch and a rounded ground plane with slots at the left and the right sides of the antenna. The parasitic strip is to enhance the bandwidth of the antenna, and it also used for improving the directional characteristic of the proposed antenna. The antenna is well designed and analyzed by using the HFSS, and the obtained results show that the antenna has a wideband bandwidth and good directional radiation patterns, making it suitable for micro-deformation monitoring radar applications.
