Abstract

The present invention provides a low-profile broadband dual-mode compressed dipole antenna, comprising: a radiating element, which is composed of a first dielectric substrate and a dipole antenna, and the dipole antenna is printed on the bottom surface of the first dielectric substrate ; The feeding balun is composed of a second dielectric substrate, a first metal ground and an "L"-shaped metal strip, the first metal ground and the "L"-shaped metal strip are respectively printed on the second dielectric substrate and an artificial magnetic conductor on which the radiating element is arranged through the feeding balun. The low-profile broadband dual-mode compressed dipole antenna of the present invention uses a feeding balun for feeding, so that the input resistance is significantly reduced, and the technical problem that the impedance of the real part of the dipole of the secondary mode is too high and difficult to match is solved. , so as to achieve good impedance matching.

Description

technical field [0001] The invention relates to the technical field of dipole antennas, in particular to a low-profile broadband dual-mode compressed dipole antenna. Background technique [0002] The antenna is an important part of the transceiver system. It mainly carries the function of transmitting and receiving electromagnetic wave signals, and plays an important role in military or civilian use. [0003] Dipoles are one of the most widely used antennas in various communication systems. In order to improve the performance of dipole antennas, scholars have done a lot of research on them. Recently, some scholars proposed a compressed dipole antenna. When the dipole is printed on the dielectric substrate, its length is compressed, and the corresponding compression factor is defined as K. By choosing the appropriate resonance mode and K value, the compressed dipole can be obtained in a smaller physical size than the traditional Dipole (K=1) higher gain. The basic compres...
