Circularly-polarized reconfigurable patch antenna shaped like Chinese character Meng

Abstract

The invention relates to a circularly-polarized reconfigurable patch antenna shaped like the Chinese character Meng, and the antenna comprises a grounding plate and a dielectric layer board, which are parallel to each other. The dielectric layer board is disposed above the grounding plate, and the upper surface of the dielectric layer board is provided with a metal piece. An L-shaped probe is disposed between the grounding plate and the dielectric layer board. The L-shaped probe consists of a horizontal rod and a vertical rod. The horizontal rod is parallel to the dielectric layer board, and the vertical rod is perpendicular to the grounding plate. The grounding plate is provided with a through hole, and the lower end of the grounding plate passes through the through hole to be connected with a coaxial connector disposed at a lower part of the grounding plate. The metal piece is shaped like the Chinese character Meng. The antenna has the reconfigurable function, enlarges a communication channel, and effectively avoids the electromagnetic coupling interference. The antenna combines the Art and Technology, is a Chinese artistic antenna, enables the Chinese character art to be integrated into the antenna design, and further spreads the spirits of the Chinese nation and the Chinese character culture.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a "dream"-shaped circular polarization reconfigurable patch antenna. Background technique [0002] With the rapid development of electronic information technology, wireless communication occupies an increasingly important position in the field of modern communication due to its own advantages. Almost all wireless communication systems need to rely on radio waves to transmit information, and the transmission of radio waves And reception needs to be done using an antenna. For example, with the continuous popularization of broadband, wireless routers have been installed in more and more families, units and other places. In densely populated areas, there are often dozens or even hundreds of signals (concentrated in the 2.45GHz radio frequency band). With the continuous increase of the internal antenna density, the electromagnetic coupling interference between the antennas becomes v...

Problems solved by technology

On the other hand, with the increase of antenna density, antennas can be seen everywhere, which not only destroys the aesthetics of the building environment, but also causes mental stress and discomfort to some electromagnetic sensitive people (electromagnetic wave sensitivity)
