Abstract

The invention provides a combined semicircular dipole printed antenna of balance microstrip line transition waveguide feed, which relates to a dipole printed antenna of balance microstrip line transition waveguide feed, and particularly to a combined semicircular dipole printed antenna of balance microstrip line transition waveguide feed. The invention solves the problems of poorer complanation, ultra-wideband, miniaturization, balance feed and directional diagraph symmetry of the traditional ultra-bandwidth antenna. A left oscillator assembly and a right oscillator assembly 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 left oscillator assembly comprises a first semiwafer, a second semiwafer and a third semiwafer which are sequentially overlapped along the width direction of the intermediate medium substrate, a transition sheet is printed on the lower surface of the other end of the intermediate medium substrate, and is connected with a short balance microstrip line on the lower surface of the intermediate medium substrate, and a fourth metalized through hole is arranged in the first semiwafer of the right oscillator assembly. The invention is used in the field of radio.

Description

technical field [0001] The invention relates to a printed antenna fed by a balanced microstrip line transitional waveguide, in particular to a combined semicircular symmetrical vibrator printed antenna fed by a balanced microstrip line transitional waveguide. 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 schemes: 1. Various special-shaped The monopole of this kind of antenna can obtain omnidirectional radiation, and if its size is miniaturized, it can beco...
