A Circularly Polarized Broadband Composite Spiral Antenna for Ground Penetrating Radar

A Circularly Polarized Broadband Composite Spiral Antenna for Ground Penetrating Radar

To enhance the capability of a ground penetrating radar (GPR) in subsurface target identification and improve its polarization sensitivity in detecting underground linear objects, a circularly polarized broadband composite spiral antenna was designed. This antenna integrates equiangular spiral and A...
