Title:
MULTI-FREQUENCY ULTRA-WIDEBAND OSCILLATOR AND ANTENNA
Document Type and Number:
WIPO Patent Application WO/2021/184967
Kind Code:
A1
Abstract:
The present invention provides a multi-frequency ultra-wideband oscillator and an antenna. The multi-frequency ultra-wideband oscillator comprises a low-frequency oscillator, a reflective plate, a first high-frequency oscillator, and two coupling feed sheets; wherein the low-frequency oscillator comprises a plurality of radiation arms, a plurality of support arms, and a base; the tops of the support arms are connected to the radiation arms, and the bottoms of the support arms are connected to the base; the radiation arms, the support arms, and the base jointly form a mounting cavity; two sides of each radiation arm are respectively provided with vertically downward bending parts; the reflective plate is fixed on the base; the first high-frequency oscillator is nested in the mounting cavity of the low-frequency oscillator, and the first high-frequency oscillator is fixed on the reflective plate; the two coupling feed sheets are orthogonally connected and are provided between the reflective plate and the base. In this way, the multi-frequency ultra-wideband oscillator of the present invention has, in a radiation direction, the effects of high front-to-back ratio, high cross polarization ratio, high isolation, and ultra-wideband.
