Abstract

The invention provides a low-profile broadband dual-mode compression dipole antenna, which comprises a radiation unit composed of a first dielectric substrate and a dipole antenna, wherein the dipoleantenna is printed on the bottom surface of the first dielectric substrate; a feed balun which is composed of a second dielectric substrate, a first metal ground and an L-shaped metal strip, wherein the first metal ground and the L-shaped metal strip are printed on the two opposite faces of the second dielectric substrate respectively; and an artificial magnetic conductor, wherein the radiation unit is arranged on the artificial magnetic conductor through the feed balun. According to the low-profile broadband dual-mode compression dipole antenna, the feed Balun is used for feeding, so that theinput resistance is obviously reduced, the technical problems that the real part impedance of a dipole of a secondary mode is too high and is difficult to match are solved, and good impedance matching is realized.

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 applications. [0003] Dipoles are one of the most widely used antennas in various communication systems. In order to improve the performance of the dipole antenna, many scholars have done a lot of research on it. 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 coefficient is defined as K. By selecting the appropriate resonance mode and K value, the compressed dipole can be obtained in a smaller physical size than the traditional Dipole (K=1) for higher...
