Embodiment Construction

[0062] Please refer to figure 1 and figure 2 As shown, it shows the specific structure of the preferred embodiment of the present invention, which is a 4G indoor wall-mounted antenna with gain, applicable to GSM, CDMA, DCS, PHS, CDMA2000, WCDMA, TD-SCDMA, WLAN, LTE, etc. The need for multi-standard indoor coverage systems increases the antenna gain, which is suitable for long-distance coverage of indoor signals and can meet the indoor coverage requirements of 4G networks.

[0063] The structure of the indoor wall-mounted antenna includes a metal carrier 10 at the bottom, a low-frequency flat panel slot antenna 20 , a high-frequency circular loop antenna 30 and a shunt filter 40 installed on the metal carrier 10 . The frequency range of the low-frequency flat panel slot antenna 20 is 806-960 MHz, and the frequency range of the high-frequency circular loop antenna 30 is 1710-2700 MHz. The design of separating the low-frequency planar slot antenna 20 and the high-frequency cir...

Abstract

The invention discloses a 4G indoor wall-mounted gain antenna. The structure of the 4G indoor wall-mounted gain antenna includes a metal carrier board disposed on the bottom, a low-frequency flat board gap antenna mounted on the metal carrier board, a high frequency ring antenna and a dividing filter. The frequency range of the low-frequency flat board gap antenna is 806-960 MHz. The frequency range of the high frequency ring antenna is 1710-2700 MHz. By the split design of the low-frequency flat board gap antenna and the high frequency ring antenna, problems such as low low-end gain, small horizontal beamwidth and poor front-to-back ratio of a traditional antenna with the low-frequency flat board gap antenna and the high frequency ring antenna combined together are avoided. Besides, since a circuit board structure of the dividing filter adopts a fan-shaped structure with better performance, the wiring structure is optimized, the filtering performance is improved and the coverage and the performance of the antenna in the wide frequency band are improved compared with like products.

Description

technical field [0001] The invention relates to antenna technology, in particular to a high-gain 4G indoor wall-mounted antenna suitable for GSM, CDMA, DCS, PHS, CDMA2000, WCDMA, TD-SCDMA, WLAN, and TD-LTE wireless communication systems. Background technique [0002] At present, there are many types of wall-mounted antennas, but most of them are single-polarized antennas. With the application of new technology standards such as LTE and WLAN, single-polarized antennas can no longer meet the requirements of new network construction. In addition, the gains of the few dual-polarized wall-mounted antennas are generally low, and the signal attenuation in the LTE and WLAN frequency bands is large, resulting in a reduction in the coverage distance of the antennas. [0003] Since the existing mobile phone mobile communication technology has developed from 2G to 3G to 4G, in order to meet the requirements of 4G mobile communication for indoor distributed coverage systems, the LTE syst...
