Design of a Wideband Receiving Antenna for High-Frequency Ground Wave Radar
The operating frequency band of high-frequency surface wave radar (HFSWR) is generally 4–9 MHz, which makes the operating frequency band of the antenna a wideband. However, it is difficult for some commonly used antennas to meet this requirement, and it is necessary to widen the antenna. In this paper, a lumped monopole antenna is designed for high-frequency surface wave radar. Genetic algorithm is employed to optimize the loading position and impedance. The operating band of the loaded antenna is wider and can meet the performance requirements of the HFSWR transmitting antenna, and the antenna size is slightly smaller than other antennas in the same band.
