Design and analysis of short helicone antenna
摘要
Abstract
A novel short helicone antenna is proposed in this paper which can be used as a cell of HPM array antenna. Mutual coupling of two short helicone antennas at different distances is simulated using the numerical simulation software. By comparing with mutual coupling of two short helical antennas in the same situation, restriction to be followed is that: when the cell distance is equal to 0. 9λ, mutual coupling of the short helicone antenna corresponded to the short helical antennas when the cell distance is smaller than 0. 9λ, mutual coupling of the short helicone antenna is bigger than the short helical antenna; when the cell distance is larger than 0. 9λ, mutual coupling of the short helicone antenna is smaller than the short helical antenna. Based on the restriction condition, a short helicone antenna is designed. At the centre frequency, the directivity of this antenna is increased by 1 dB, the sidelobe is 7 dB lower than that of the short helical antenna. The mutual coupling between two short helicone antennas is 3 dB smaller than that of two short helical antennas in the same situation.关键词
