Design of Ultra Wide-Band Transmit/Receive Antenna Pair for Vehicle Based Ground Penetrating RADAR

This paper tries to elaborate the design of an Ultra Wide Band Antenna (single element), which is used as vehicle mounted ground penetrating Radar to identify landmines. A reflector for the antenna, transmit and receive pair, and finally array of these elements operating up to 3 GHz is subsumed in this design. Triangular micro-strip patch antenna (Idea from conical antenna, which has good Ultra Wide Band quality), focusing on the most important aspect of Miniaturization of antenna (finally 13X15 cm), providing larger perimeter for smaller frequency range and larger area for large Bandwidth, which lead to a hybrid design consisting of a triangle and ellipse, thus also removing edges but burgeoning size. Meticulously considering various parameters like Return loss, BW, VSWR, Beam angle, radiation pattern, realized gain and impedance, the final design achieves the desired requirement. Designing and simulation is performed on High Frequency Structure Simulator (HFSS) V 12.0 and loading and retesting is performed with the help of Time domain solver XFDTD V 7.1.0
