Abstract

The present invention relates to a broadband bow-tie symmetrical folded dipole antenna. The folded dipole antenna has an upper and lower plane structure parallel to each other. The upper plane structure is the first radiation part, and the lower plane structure is the second radiation part. The first radiation There is a supporting part between the first radiation part and the second radiation part. The first radiation part is composed of a dielectric plate with a radius of R and a copper-clad surface covered with it. The outer edge of the copper-clad surface is a bow tie with a narrow middle part and wide sides The folded vibrator structure is horizontally and vertically symmetrical. Adopting the technical scheme of the invention, on the one hand, it has a compact structure that is convenient for fixed installation, and on the other hand, it can maintain stable gain and radiation performance in the whole broadband range.

Description

technical field [0001] The invention relates to the technical field of broadband or multi-band wireless communication and radio frequency energy collection, in particular to a broadband bow-tie symmetrical folded dipole antenna. Background technique [0002] With the development of wireless communication technology, more and more communication frequency bands are used by people, such as: 2G, 3G, WLAN and so on. Therefore, there are more and more requirements for designing multi-band wireless communication antennas, and such antennas need to have a wider operating frequency band and a more stable gain. The folded dipole antenna is one of the antennas that are easier to achieve broadband characteristics. In recent years, the research on the folded dipole antenna has attracted attention at home and abroad [1]-[9]. Document [1] proposes a miniaturized folded dipole antenna working at 27MHz-43MHz. Document [2] is a high-gain antenna array for dual-band WLAN and WiMAX. The array...
