Folded oscillator antenna

Abstract

A folded oscillator antenna comprises a support, two support structures, two radiating arms, two input ends and two loading ends, wherein the two support structures are symmetrically arranged at a left side and a right side of the support, each support structure comprises a round pipe and a non-metal round cover, the non-metal round cover sleeves one end, near to the support, of the round pipe so as to fix the round pipe and the support, each radiating pipe comprises a metal round cover and two metal strips, the metal round cover is arranged at one end, far away from the support, of the round pipe, the two metal strips are symmetrically arranged on an upper surface and a lower surface of the round pipe and are electrically connected with the metal round cover, the two input ends are led out of the metal strips on the upper surface or the lower surface of the round pipe of each radiating arm, and the two loading ends are led out of the other metal strip, except the metal strip used as the input ends, in the two metal strips of each radiating arm. By the folded oscillator antenna, integration of the support structures and the antenna is achieved, and the folded oscillator antenna has the advantages of light weight and a simple structure, can be folded and can be used as an antenna of a high-frequency radar moving on ground and a satellite-borne platform.

Description

technical field [0001] The invention relates to the field of wide-band high-frequency ranging radar, in particular to a folded dipole antenna. Background technique [0002] The wideband antenna is an important part of the ranging radar system, and its performance has an important impact on the overall performance of the radar system. Broadband high-frequency ranging radar systems mostly use wideband frequency sweep coded signals or linear frequency modulation signals, so the antenna should have good radiation characteristics and broadband impedance characteristics. Whether the antenna can be easily folded and unfolded determines whether the radar system can be applied to ground mobile or spaceborne platforms. The mobile platform requires that the antenna and its supporting structure need to achieve an integrated design to reduce weight, and can be folded to reduce volume. At present, the antennas commonly used in broadband high-frequency ranging radars are mostly resistanc...
