Abstract

The invention relates to an ultra-wideband antenna and a resonance method thereof. The ultra-wideband antenna is characterized in that two working modes at low frequency and two working modes at highfrequency are excited at the same time by a matching structured synthesized by double-F-shaped routing, and five resonance working modes are achieved by the four working modes and one self-resonance of an antenna body at high frequency. The ultra-wideband antenna structurally comprises a printed circuit board 5 and an antenna component and is characterized in that the antenna component is arrangedat the upper end of the printed circuit board to form the whole antenna system; the antenna body is connected with a transceiver through a feeder, the other end of the feeder is connected with a feedsource, a grounding wire attaches to a support and is connected with the antenna body and the printed circuit board through a matching circuit, and five resonance working modes are excited by the joint effect of the matching structure, the antenna, the feeder and the grounding wire. The ultra-wideband antenna has the advantage that the five resonance working modes are excited by the joint effectof the matching structure, the antenna, the feeder and the grounding wire to achieve frequency coverage of low frequency 80-1400MH and high frequency 2-4.5GHz and a wideband effect.

Description

technical field [0001] The invention relates to the technical field of new mobile terminal antennas, in particular to a design of ultra-wideband antennas for SUB-6G, and in particular to a mobile terminal antenna that utilizes dual resonances to simultaneously achieve high and low frequency broadband coverage. Background technique [0002] Modern wireless communication devices are required to cover as wide a frequency band as possible to achieve more functions, especially in the 5G communication era, all frequency bands of 2G / 3G / 4G also need to be compatible. But for the built-in antenna, the antenna design has great constraints in a limited space, and it is difficult to achieve a wide frequency band. The invention provides an ultra-wideband Sub-6G antenna, the frequency covers 800-1400MHz and 2-4.5GHz, and simultaneously realizes high efficiency and high gain performance. Contents of the invention [0003] In order to realize the purpose of the present invention, a kind ...
