Abstract

The invention discloses a Q-band ultra wideband half-plane terminal antenna. The antenna is of a plane structure, comprising a dielectric substrate, a double dipole oscillator which is arranged on the dielectric substrate as a radiating unit, a feed network for energy distribution, an equivalent SIW (Substrate Integrated Waveguide) semi-opened cavity through which the half-plane radiation of the antenna can be achieved and the beam width can be controlled, and a plurality of metallic through holes formed in the dielectric substrate; the SIW semi-opened cavity can be also used for adapting the antenna to the SIW while considering the balun, electrostatic shielding and wideband matching effect. In light of the development demand of terminal antennas, the antenna is small in non-circularity, high in efficiency, and ultra-wide in band, the beam width is easily controlled, and the integration is easily carried out.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a Q-band ultra-wideband half-planar terminal antenna. Background technique [0002] The terminal antenna is an important part of the wireless communication system. In recent years, with the continuous advancement of modern wireless communication technology, higher and higher requirements have been placed on mobile terminal antennas. On the one hand, the coexistence of multiple communication systems requires mobile terminal antennas to cover a wide frequency band; on the other hand, as a part of the communication system, the physical size of the terminal antenna should not be too large. The substrate base plate is not very sensitive to changes in the relative position. [0003] At present, scientific researchers have carried out a lot of research on terminal antennas in the radio frequency band, and a large number of planar or quasi-planar structures have been deeply studi...
