Abstract :
A miniaturized double-ridged horn antenna for use as an array element in the Subsurface Radar (SR) system is presented. SR has been proposed for some emerging applications such as breast imaging and wood inspection. A cylindrical scanning geometry is proposed which will host 72 antennas in a row for illuminating the target and receiving scattered signal. The scanning system will have several rows of antennas for better sensitivity and spatial accuracy. The designed double-ridged horn antenna shows promising results with good transmission characteristics.
