Abstract

The invention discloses a miniaturized short-wave soft oscillator log-periodic antenna, which comprises an antenna supporting tower, an antenna curtain and a metal structure truss, the metal structure truss comprises a main truss, an empennage truss and a front wing truss; the main truss comprises a center support, a rear vertical rod and a front vertical rod. The center support is arranged on the main truss in the direction of the extension line of the antenna supporting tower, the rear vertical rod is located at the joint of the main truss and the empennage truss, and the front vertical rod is located at the joint of the main truss and the front wing truss. The antenna curtain comprises an antenna oscillator, an assembly line and a side sling. The assembly line is hung between the rear vertical rod and the front vertical rod, the side sling is hung at the tail end of the front wing truss and the tail end of the tail wing truss, and the antenna oscillator comprises a plurality of pairs of proportional three-dimensional triangular oscillators and planar quadrilateral oscillators. The antenna has small characteristic impedance and Q value, the working bandwidth of the antenna is widened, and the physical size of the antenna is reduced.

Description

technical field [0001] The invention belongs to the technical field of radio short-wave communication, and in particular relates to a miniaturized short-wave soft oscillator logarithmic periodic antenna. Background technique [0002] The log-periodic antenna belongs to the non-frequency-variable antenna, which has good directivity, high gain, high radiation efficiency and wide-band operating characteristics, making it widely used in ultrashort wave and short wave bands. The log-periodic antenna is composed of multiple pairs of dipole oscillators and assembly lines, and each pair of oscillators is arranged crosswise on both sides of the assembly line according to a certain length and spacing ratio. The electrical performance of the antenna is closely related to its structural size. The length of the longest vibrator of the antenna is about a quarter of the wavelength of the lowest operating frequency. [0003] In the field of radar or electronic reconnaissance, log-periodic ...
