Description
Technical field
The utility model belongs to the communication antenna field, and specifically a series of sector array antennas can be used as the polarization diversity antenna and the sector cover antenna battle array of PHS base station.
Background technology
Along with the development of telecommunications, people are to mobile communication, and particularly the quality of PHS Personal Handyphone System communication system is had higher requirement, and the raising of communication quality, i.e. one of important means of signal strength signal intensity increase is exactly to increase base station density.But the increase of base station number not only can take up space, and influence is beautified the environment, and increases input.Therefore, how to utilize existing base station and improve the performance of antenna itself, just become to solve the important means of mobile communication quality problems.In order to overcome in mobile communication system and PHS Personal Handyphone System communication system because the received signal decline that the multipath transmission causes can be adopted space diversity or polarization diversity reception technique usually.Yet, because except the received signal decline that the multipath transmission causes, also there is the uncertainty of transmitting signal polarization vector in the existence of factors such as building and hypsography.When receiving and transmitting antenna polarizes when identical, efficiency of transmission is the highest.If when both polarization have certain included angle, then have polarization loss.For example, a vertical polarized antenna can only receive vertically polarized wave, can not receive horizontal polarized wave; And for example: when receiving vertically polarized wave with 45 ° of poliarizing antenna, 3 decibels of received power losses.In order to overcome these losses, the multi-polarization antenna that need have several different polarization receives, and selects maximum received signal, obtains best reception.At present, the dual-polarized directional base station antenna that mainly adopts the sector to cover is realized the polarization diversity of each sector, or adopts the directional base station antenna of two sides single polarization, realizes the space diversity of each sector.And for the omni-base station antenna that omnidirectional covers, in practical engineering application, mainly be to adopt the structure of overpaying single polarization omnidirectional antenna implementation space diversity.In order to realize the polarization diversity of coverage base station system of omnidirectional, ° directional bipolarization antenna integrated combining structure in three sectors ± 45 has appearred in the prior art, as " the Personal Handyphone System PHS communication system omnidirectional intelligent aerial of polarization diversity " of Xi'an Haitian Antenna Sci-tech Co., Ltd.'s development, this antenna is exactly integrated three sectors ± 45 ° of dual polarization diversity omnidirectional antennas.But each the synthetic gain in handing-over zone in three sector combination is lower, do not reach the yield value that general omnidirectional antenna is 11dB, make at these regional omnidirectional's coverage effects relatively poorly, the omnidirectional that has influenced the base station covers and omnibearing polarization diversity performance, causes the deficiency of Personal Handyphone System signal difference.In prior art the integrated combining structure of six sectors, four polarization omnidirectional antennas has been arranged also, " four polarization, six sector diversity omnidirectional antennas " as Xi'an Haitian Antenna Sci-tech Co., Ltd.'s exploitation, this antenna adopts six sector dual polarized antenna group formation to help to radiation, can carry out work with four kinds of polarization modes, produce four input/output end ports.Existing PHS base station such as the 500mW1C7T of UtStarcom, be eight antenna connection terminal mouths mostly, so as mating use with existing base station system, two sides " four polarization, six sector diversity omnidirectional antennas " just need be set up in a 500mW1C7T base station, cost is than higher.
