Abstract

An embodiment of the present invention provides a plasma dielectric resonant antenna, including a plasma bulb, a dielectric resonator, and a dielectric substrate, wherein: the dielectric resonator is fixed on the upper surface of the dielectric substrate, the dielectric resonator has a first through hole, and the dielectric substrate has a The second through hole, the plasma bulb is fixed in the dielectric resonator, and connected to the external power supply through the first through hole and the second through hole; the lower surface of the dielectric substrate is provided with a feed network, and the feed network is used to connect the transmitter The modulated signal is transmitted to the antenna composed of the plasma bulb and the dielectric resonator through the dielectric substrate, and the antenna converts the modulated signal into a radio signal and sends the radio signal. By adopting the embodiment of the present invention, the radiation pattern of the antenna can be changed.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a plasma dielectric resonant antenna. Background technique [0002] As an indispensable part of radio equipment, antenna can play the role of sending and receiving radio signals. The radiation pattern of the antenna refers to the graph in which the relative field strength of the radiation field of the antenna changes with the direction of the antenna at a certain distance from the antenna, which can represent the range that the signal emitted by the antenna can cover. [0003] At present, the radiation pattern parameters of the antenna are usually fixed. For example, the radiation pattern parameters such as half-power lobe width, main lobe width, and front-to-back ratio are all fixed, which leads to the signal emitted by the antenna. The coverage area is also fixed. [0004] Therefore, in an environment with a relatively complex building layout, the range that th...
