Embodiment 1

[0023] Referring to the accompanying drawings, the present invention forms a multi-frequency and multi-standard base station by placing two columns of dual-frequency antenna arrays 01, 01' and one column of single-frequency antenna arrays 02 side by side on the same reflector and combining them into a unified radome antenna. The dual-frequency antenna array includes a high-frequency antenna unit 012 and a low-frequency antenna unit 011. The high-frequency antenna unit 012 is located at the center of part or all of the low-frequency antenna unit 011 and between two adjacent low-frequency antenna units 011. Two rows of dual-frequency antenna arrays It has structural symmetry; the single-frequency antenna array is composed of several high-frequency antenna units 012

[0024] refer to figure 1 , two columns of dual-frequency antenna arrays 01 and 01' have structural symmetry on the y-axis, two columns of dual-frequency antenna arrays and one column of single-frequency antenna arr...

Embodiment 2

[0028] Such as figure 2 As shown, the difference between this embodiment and Embodiment 1 is that the single-frequency antenna array 02 is placed in the center of the reflector and arranged along the X-axis direction, and is misaligned with the high-frequency antenna unit in the dual-frequency antenna array in the Y-axis direction arrangement.

Abstract

The invention discloses a multi-standard antenna, comprising a reflecting plate, as well as a dual-frequency antenna group and a single-frequency antenna group, which are arranged on the reflecting plate, wherein the dual-frequency antenna group comprises two rows of dual-frequency antenna arrays arranged in parallel, each dual-frequency antenna array further comprises a high-frequency antenna unit and low-frequency antenna units, each high-frequency antenna unit is arranged at the center of part of or both of the low-frequency antenna units and between the adjacent two low-frequency antenna units, and the two rows of the dual-frequency antenna arrays have the structural symmetry; and the low-frequency antenna group is a single-frequency antenna array arranged on the symmetric axis of the two rows of the dual-frequency antenna arrays, and the single-frequency antenna array comprises a plurality of high-frequency antenna units. The multi-standard antenna can be shared by more than 5 communication standards, and the downward inclination angle under each standard can be independently and electrically controlled; and the overall antenna is compact in structure, the isolation degree under all the standards is high, and the structural reliability is high.

Description

[technical field] [0001] The present invention relates to the field of mobile communication, in particular to a mobile communication electrical adjustment base station antenna shared by multiple systems. [technical background] [0002] With the rapid development of wireless communication and the continuous increase of mobile communication services and types, the second generation, third generation, third generation and WLAN / WiMAX wireless systems coexist. Compatible with broadband needs of multiple standards. At present, the second-generation CDMA800 frequency band is 824-896MHz, the GSM900 frequency band is 870-960MHz, the DCS1800 frequency band is 1710-1880MHz, the PCS1900 frequency band is 1850-1990MHz, and the third-generation UMTS frequency band is 1920-2170MHz. Among the mature products, there are already base station antennas that can support 2 and 3 systems at the same time, but there are no reports of electric-tunable base station antennas that can support 5 or mor...
