Title:
ULTRA-WIDEBAND ANTENNA USING WAVE ABSORBING MATERIAL AND DIELECTRIC
Document Type and Number:
WIPO Patent Application WO/2023/005399
Kind Code:
A1
Abstract:
The present invention relates to the technical field of antennas, and disclosed is an ultra-wideband antenna using a wave absorbing material and a dielectric. The antenna comprises an upper fixing plate and a lower fixing plate; a left side plate and a right side plate are respectively fixed between the upper fixing plate and the lower fixing plate; the upper fixing plate, the lower fixing plate, the left side plate, and the right side plate are fixed together to form a cylindrical structure having a small opening at the left end and a large opening at the right end; a cavity is fixed at the opening of the left end of the cylindrical structure; a first wave absorbing material block is fixed in the cavity; an upper ridge and a lower ridge are provided in the cylindrical structure; tail ends of the upper ridge and the lower ridge are inserted into the first wave absorbing material block; the upper ridge and the lower ridge are provided oppositely, and a dielectric rod is provided between the upper ridge and the lower ridge; and second wave absorbing material blocks are respectively formed on the upper fixing plate at the two sides of the upper ridge and the lower fixing plate at the two sides of the lower ridge.
