Technical field
The utility model relates to wireless communication technology, is specifically related to vertical, the directed plate antenna of horizontal double poleization.
Background technology
Dual polarized antenna is a kind of new antenna technology, has made up 90 ° of Orthogonal Double polarization, is operated in simultaneously under the transmission duplex pattern, and each sub-district only needs a secondary dual polarized antenna, so its most outstanding advantage is to save the antenna amount of single directional base station.
The directional base station (three sectors) of general GSM digital mobile communication network will use 9 antennas, and 3 antennas of each fan-shaped use (space diversity, one two receipts) are if use dual polarized antenna, 1 antenna of each fan-shaped needs; Simultaneously because in dual polarized antenna, ± 45 ° polarization orthogonal can guarantee+isolation between 45 ° and-45 ° of two slave antennas satisfy intermodulation to the requirement of isolation between antennas (〉=30dB), so the space interval between the dual polarized antenna only needs 20-30cm; In addition, dual polarized antenna has the advantage of electrical tilt antenna, uses dual polarized antenna the same with electrical tilt antenna in mobile radio communication, can reduce call loss, reduces to disturb, and improves the service quality of the whole network.
When omni cell splits into three sub-districts, at most only increase common antenna (former omni cell is 2 slave antennas at dual-mode).Traditional single-polarized antenna, when omni cell is split into three sub-districts, antenna amount sharp increase (even when dual-mode, also increasing by 4 pairs at least), because (RX-TX between the antenna, isolation TX-TX) (〉=30dB) and between the space diversity reception to communicate requirement antenna level and perpendicular separation distance are arranged, at this moment must enlarge the platform that fixes up an aerial wire, increase capital expenditure.
