The foliage penetration radar system operates in the VHF/UHF range of the electromagnetic spectrum, allowing for greater radio frequency penetration compared to microwave frequencies while providing improved range and significant cross-range resolution. The multi-static ground-based foliage penetration radar comprises a transmitting and a receiving antenna. The unidirectional radiating transmitting antenna utilizes a VHF wideband transmitting signal, achieving fine localization accuracy over a larger coverage area while effectively penetrating foliage. However, achieving significant antenna gain or directivity while maintaining an acceptable size at VHF/UHF frequencies presents challenges. This paper focuses on the design and simulation of an antenna tailored for foliage penetration applications, emphasizing the balance between size and directivity.
