Design and Implementation of a Dual-Frequency Compact Antenna System for HF Radar

A novel dual-frequency compact antenna system designed for high-frequency radar is proposed and fabricated. The dual-frequency antenna system is composed of three sensing elements: a monopole and two crossed-loop antennas. A concise switch module based on symmetric p-i-n diodes is applied to the ant...

Description
Summary:A novel dual-frequency compact antenna system designed for high-frequency radar is proposed and fabricated. The dual-frequency antenna system is composed of three sensing elements: a monopole and two crossed-loop antennas. A concise switch module based on symmetric p-i-n diodes is applied to the antenna for dual-frequency operation. This designed antenna can achieve equivalent performance of corresponding single-frequency antenna at each frequency. The dual-frequency response characteristics, as well as results of measured antenna patterns and experimental sea echo spectra, are given to prove the validity of the antenna system design.
