A review on ultra-wideband antennas for through wall imaging and ground penetrating radar applications

This paper presents the review on the design of various ultra-wideband antennas through wall imaging in radar applications. The technical and methodological features in the design of ultra-wideband is examined in this work. The parameters such as gain, directivity, frequency bandwidth sidelobe level and complexity involved in the design are studied. Furthermore, the image resolution and penetration depth required for Ground Penetrating Radar systems depends on the antenna parameters are analyzed in detail. The proposed manuscript gives a depth study of the suitable antenna design for penetrating ground radars. The comparative study is made on the various types of UWB antenna with a focus (a) To highlight the requirement for UWB antennas in wall imaging radar imaging systems (b) To describe the techniques used to enhance the performance of the antenna.
