Abstract

The invention provides a balance microstrip line transition full-mode dual-ridged integrated waveguide feed dipole printed antenna which relates to a dipole printed antenna, and particularly to a balance microstrip line transition full-mode dual-ridged integrated waveguide feed dipole printed antenna. The invention solves the problems that the traditional balance microstrip line feed antenna can not be beneficial to application to an occasion needing longer feed distance due to larger radiation loss and a substrate integrated waveguide single-mode working bandwidth is narrower. A left oscillator and a right oscillator are symmetrically printed on the upper surface of the other end of an intermediate medium substrate along a center line of the intermediate medium substrate, the straight side of the left oscillator and the straight side of the right oscillator are respectively in parallel to the center line of the intermediate medium substrate and are far away from the center line, the arc-shaped side of the left oscillator is connected with a short balance microstrip line on the upper surface of the intermediate medium substrate, a load wafer is connected with the arc-shaped side of the left oscillator, and the middle of the arc-shaped side of the right oscillator is provided with a fourth metalized through hole. The invention is used in the field of radio.

Description

technical field [0001] The invention relates to a symmetrical vibrator printed antenna, in particular to a balanced microstrip line transition full-mode double-ridge integrated waveguide fed symmetrical vibrator printed antenna. Background technique [0002] Ultra-wideband antennas have a very wide frequency band and can transmit information at high speed in wireless transmission, so they have received widespread attention. There are many definitions of ultra-wideband at present. The frequency band of civilian ultra-wideband specified by the US Federal Communications Commission (FCC) is 3.1GHz -10.6GHz, its specific bandwidth reaches 3.42:1, and the definition of ultra-wideband antenna is usually more than 2:1. For the research of ultra-wideband antenna, researchers have proposed a variety of solutions: 1. Various special-shaped The monopole of this kind of antenna can obtain omnidirectional radiation, and if its size is miniaturized, it can become a time-domain antenna; Sec...
