Embodiment Construction

[0029] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0030] As shown in Figure 1, a schematic diagram of the layout positions of two antennas of the PCMCIA data card of the application example of the present invention:

[0031] On the PCMCIA data card, the main antenna 1 is a built-in antenna, located at the front of the main board 6, with a size of 3*3*20mm. It is fixed to the main board by welding, and its direction is perpendicular to the long side of the main board. The distance between the center of the main antenna 1 and the main board 6 is The bottom end of the 68PIN connector 10 is 103mm. The main antenna feed point 2 is on the left side of the main board 6, 1.2mm away from the left board edge. The main antenna 1 is connected to the main antenna feed point 2 through soldering. The network 7 is connected, and the main antenna π-type matching network 7 is connec...

Abstract

The utility model discloses a PCMCIA data card, comprising a main antenna, a main antenna feeding point, a polarization diversion antenna, a polarization diversion antenna feeding point, a main board, two Phi-shaped matched networks, a main board transmitting / receiving sub-circuit, and a main board polarization diversion sub-circuit, wherein both the main antenna and the polarization diverse antenna are built-in antennas which adopts vertical and orthogonal means, The utility model also discloses a method of realizing the PCMCIA data card polarization receiving antenna, the realized main antenna comprises seven frequency bands: WCDMA2100 / WCDMA1900 / WCDMA850 / GSM850 / GSM900 / GSM1800 / GSM1900. The PCMCIA data card built in the polarization diversion antenna is built in the main antenna where the polarization diversion antenna comprises six frequency bands: WCDMA2100 / WCDMA1900 / WCDMA850 / GSM850 / GSM1800 / GSM1900.

Description

technical field [0001] The invention relates to a mobile terminal technology, in particular to a PCMCIA (Personal Computer Memory Card International Association, Personal Computer Memory Card International Association) data card and an antenna method for realizing diversity reception thereof. Background technique [0002] During the transmission of wireless signals, due to terrain undulations, buildings, obstacles, and the interaction of direct waves, reflected waves, and scattered waves generated by various objects in the transmission path, fading effects will occur, resulting in a significant bit error rate. Improve, thus seriously affecting the reliability of the communication link. [0003] Diversity Receive (Diversity Receive) refers to the use of two (or more) sets of receiving equipment to receive the same signal transmitted by the transmitting equipment through two (or more) different paths, and the two channels ( or multiple) signals, and after some processing, the...
