The invention discloses a high-order mode resonance-based Q-band ultrahigh-speed wireless local area network mobile terminal antenna, which comprises a dielectric substrate, an antenna radiation unit and a metal grounding plane, wherein the antenna radiation unit comprises a main rectangular radiation unit, a short-circuit branch strip, a feed branch strip, a rectilinear open-circuit branch strip, an L-shaped open-circuit branch strip and a q-shaped branch strip; the radiation unit structurally consists of a planar inverted F-shaped antenna with high-order mode resonance characteristics, and a plurality of resonance branches are added to realize broadband work and endow the antenna with omnidirectional radiation characteristics in a main tangent plane of a magnetic field. Compared with the prior art, the mobile terminal antenna has the advantages that the Q-band mobile terminal antenna which is simple in structure and small in size is designed for the characteristics of a millimetric wave band (45GHz) by virtue of a printed circuit process, has the characteristics of broadband, low standing wave ratio, omnidirectional radiation, easiness in integration, higher accuracy and high repeatability, and also has the advantages of low cost, convenience in batch production and the like.
Description
technical field [0001] The invention belongs to the technical field of wireless communication, in particular to a Q-band ultra-high-speed wireless local area network mobile terminal antenna. Background technique [0002] Based on the sufficient spectrum resources in the millimeter-wave frequency band, the development and development of a new generation of ultra-high-speed wireless LAN communication standards and systems is becoming an important direction for the future development of wireless communication networks. According to the frequency planning of the Ministry of Industry and Information Technology of my country, the 42.4-48.4GHz spectrum resources in the Q-band have been designated as ultra-high-speed wireless LAN services and announced at the end of 2013. The communication standardization work related to this frequency spectrum is being carried out extensively. Among them, the 802.11aj (45GHz) standard working group was established in 2012 with the permission of the...
