Abstract

The invention provides a microstrip printing dipole antenna. The dipole antenna comprises a printing plate, two surfaces of the printing plate are symmetrically provided with metal transmission lines of good conductors, the metal transmission lines form two arms of the dipole antenna, a microstrip transmission line, and two microstrip baluns, the microstrip transmission line is a double-transmission-line structure, two arms of the dipole antenna and two microstrip baluns are respectively and symmetrically arranged at two ends of the microstrip transmission line, the microstrip baluns are in the shape of right angle trapezoids, and the lower bottoms of the trapezoids are connected to the microstrip transmission line. The microstrip printing dipole antenna is advantaged by light weight, small size, low cost, convenient integration and array composition, and the application demand of miniaturization of electronic products is met.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a microstrip printed dipole antenna. Background technique [0002] Dipole antennas are used to transmit and receive fixed frequency signals. Although wideband antennas are used in usual measurements, dipole antennas are required to be used in site attenuation and antenna coefficient measurements. As people's requirements for communication quality and integration of communication equipment continue to increase. As a sub-component of communication equipment, antennas also require higher performance to meet the needs of communication systems. Nowadays, a printed dipole antenna has appeared, which prints dipoles on a thin dielectric substrate. It is light in weight, easy to process and provides a wide bandwidth and advanced purity. The structure of the antenna is: With the printed board as the support, the dipole is set on one side, and the matching feeder is set on the othe...
