R. Nilavalan et al., Wideband printed bowtie antenna element development for post reception synthetic focusing surface penetrating radar, ELECTR LETT, 35(20), 1999, pp. 1771-1772
A printed bowtie antenna for a post-reception synthetic focusing surface pe
netrating radar (PRSF-SPR) has been developed with the aid of finite differ
ence time domain analysis. Antenna free space characteristics were compared
against practical measurements and the performance of the antenna was anal
ysed when soil is present.
