Abstract

The invention relates to a wheel type electromagnetic dipole wifi dual-frequency antenna, and relates to the technical field of communication antennae. The wheel type electromagnetic dipole wifi dual-frequency antenna comprises a microstrip monopole antenna and a magnetic dipole antenna, the microstrip monopole antenna comprises a microstrip line, the microstrip line is provided with a fixed plate, the magnetic dipole antenna comprises a hollow fixed disc, and the fixed disc sleeves the peripheral side of the fixed plate; the magnetic dipole antenna further comprises a first metal ring set and a second metal ring set, the first metal ring set and the second metal ring set are arranged in an upper layer and a lower layer, the first metal ring set is arranged on the inner wall of one end of the fixing disc, and the second metal ring set is arranged on the inner wall of the other end of the fixing disc in a lifting mode. The fixing plate is provided with a driving assembly used for driving the second metal ring set to be close to or away from the first metal ring set. According to the wheel type electromagnetic dipole wifi dual-frequency antenna, the microstrip monopole antenna and the magnetic dipole antenna are good in impedance matching and are horizontally symmetrical in structure, so that the wheel type electromagnetic dipole wifi dual-frequency antenna has high out-of-roundness.

Description

technical field [0001] The present application relates to the technical field of communication antennas, in particular to a wheel-type electromagnetic dipole wifi dual-frequency antenna. Background technique [0002] The wireless local area network device works in two frequency bands whose center frequencies are 2.4GHz and 5.8GHz. With the development of 5G technology, users have higher and higher requirements for the performance experience of terminal products. For the efficiency, many LAN devices install multiple antenna arrays composed of antenna elements to form dual-band antennas. [0003] Existing wifi dual-band antennas generally use a hybrid feeding method, through a feeding node to complete simultaneous feeding of two frequency bands, the performance of the wifi dual-band antenna is mainly reflected in the strength of the signal, the signal The strength is related to factors such as the impedance matching of the antenna and the horizontal plane non-circularity of ...
