10m shortwave whip broadband antenna

TLDR: In this paper, a 10m shortwave whip broadband antenna is characterized in which the upper radiator, the upper matching circuit, the lower radiator and the lower matching circuit are sequentially connected through a wire in series to form an antenna body.

Abstract: The invention relates to a 10m shortwave whip broadband antenna, and belongs to the technical field of communication antennas The 10m shortwave whip broadband antenna comprises an upper radiator, an upper matching circuit, a lower radiator and a lower matching circuit; the 10m shortwave whip broadband antenna is characterized in that the upper radiator, the upper matching circuit, the lower radiator and the lower matching circuit are sequentially connected through a wire in series to form an antenna body; and the upper matching circuit is connected with an input/output port of the antenna through a 50ohm radio-frequency socket A smooth change of radio-frequency port impedance within a frequency range of 3-30MHz is achieved; and the voltage standing wave ratio index of the antenna body at a 95% band within the range of 3-30MHz is not greater than 3 A shortwave broadband high-speed frequency hopping technology is supported; the circuit structures are simple; working is stable and reliable; and the cost is low The problems that the circuits are complicated, the cost is high, the working reliability is low, an internal mechanical or electronic switch is low in switching speed and the shortwave broadband high-speed frequency hopping technology is seriously restricted since an active antenna tuner needs to be configured in the prior art are solved
