Abstract

The invention relates to an ultra wide band H-type cross type dielectric resonator antenna, which comprises a dielectric substrate, a metal floor, and a direct micro-strip feeder line and a monopole antenna on the dielectric substrate, wherein a crossed H-type dielectric resonator is put on the dielectric substrate; due to the cross-type structure, the H-type dielectric resonator is embedded on two sides of the dielectric substrate; the monopole antenna is arranged in an open pore in the lower end of the front face of the dielectric resonator; the upper end of the direct micro-strip feeder line is connected with the monopole antenna; and a terminal of the direct micro-strip feeder line is connected with a coaxial connector. The ultra wide band H-type cross type dielectric resonator antenna has a simple structure, a smaller size and larger wide band, can effectively cover frequency requirement regulated by FCC (Federal Communications Commission), i.e. 3.1-10.6GHz, has good directionality and higher gain and emission efficiency, and is very suitable for miniaturization development demand and application of modern ultra wide band wireless communication.

Description

technical field [0001] The present invention relates to an ultra-wideband H-type crossed dielectric resonator antenna, in particular to an antenna that realizes ultra-wideband by combining an H-type crossed dielectric resonator and a monopole antenna, and has an ultra-wideband antenna working bandwidth. The antenna can be used as an ultra-wideband wireless communication terminal antenna. Background technique [0002] According to the standard released by the FCC (Federal Communication committee) in 2002: the absolute bandwidth is greater than 500MHz, or the relative bandwidth is greater than 20%, and the working frequency band is 3.1-10.6GHz. The characteristic of UWB communication is that the transmission rate is >100Mb / s, the transmission distance is small, and the power is extremely small. It has potential application prospects in wireless communication and radar imaging. [0003] Since the dielectric resonator has been used as an antenna as a radiator, the dielectri...
