Embodiment Construction

[0027] The technical solution of the present invention will be further elaborated below in conjunction with the drawings and specific embodiments.

[0028] In order to simplify the PCB layout and solve the problem of signal interference and loss in the receiving mode of the antenna, the present invention uses the main and auxiliary antennas of the dual-mode terminal to share an antenna support, and introduces an LC resonance circuit before each antenna feed point To achieve the above-mentioned purpose of the invention.

[0029] The dual-mode terminal antenna based on the above improvement includes a main antenna and a secondary antenna. The primary antenna is composed of a primary antenna of the first standard and a primary antenna of the second standard, and the secondary antenna is composed of a secondary antenna of the first standard and a secondary antenna of the second standard. Antenna composition; the dual-mode terminal antenna also includes an antenna bracket, the main ante...

Abstract

The invention discloses a bi-module terminal antenna, comprising main antennas, secondary antennas and an antenna bracket; the main antenna is formed by a main antenna with a first system and a main antenna with a second system, the secondary antenna is formed by a secondary antenna with the first system and a secondary antenna with the second system, the main antennas and the secondary antennas are fixed on the same antenna bracket, and reeds are respectively arranged on the main antennas and the secondary antennas; when the antenna bracket is buckled on a main board, four reeds of the main and secondary antenna are respectively contacted with four antenna feed points on the main board; an LC resonance circuit is arranged in front of each antenna feed point, four LC resonance circuits respectively works in working frequency ranges of the connected antennas corresponding to the antenna feed points. The invention further discloses a signal processing method, signal high resistance at different frequency ranges is carried out by the LC resonance circuits, so as to solve the signal disturbance and lost problems in the prior art under a condition that the antenna is in a receiving mode; in addition, the bi-module terminal antenna in the invention simplifies the layout of a printed-circuit board (PCB).

Description

Technical field [0001] The present invention relates to the field of antenna design of mobile terminals, in particular to a dual-mode terminal antenna supporting Worldwide Interoperability for Microwave Access (WIMAX) and a signal processing method. Background technique [0002] With the increasing development of wireless technology and the increasing popularity of notebook computers, it is becoming more and more popular to use notebook computers to surf the Internet. WIMAX is a new third-generation mobile communication (3G, 3rd-Generation) standard. Due to the current network coverage of WIMAX, there are certain problems. Therefore, in order to meet the needs of users to access the Internet anytime, anywhere, dual-mode terminals of WIMAX+ other standards are used. It seems very necessary, for example: WIMAX+ data evolution (EVDO, Evolution Data Only) dual-mode terminal. Among them, the full name of EVDO is CDMA2000 1xEV-DO, which is a stage of the evolution path of CDMA2000 1x....
