Description
Technical field
The present invention relates generally to fan anteena (sector antenna), and relate more specifically to be used for the system and method for configurable fan anteena, this fan anteena have can be based on the characteristic of effective radiating curtain with the radiation of one of a plurality of segment angles so that cover a plurality of radiating curtains of a sector in a plurality of sectors (sector area).
Background technology
Antenna is the electric device of emission or received signal.More specifically, antenna take on radio frequency (RF) energy emission to extraneous or from extraneous received RF energy via port.Common antenna is an omnidirectional antenna.Omnidirectional antenna is on all directions, basically with 360 degree mode radiations.Yet such antenna is not the effective solution of the stronger problem of the directionality of requirement radiation or focusing.The single robust antenna that radiant power can be focused on one of a plurality of specific regions is desirable, partly cause is its effective power division, and partly cause is aborning directly cost savings and may use in more advanced commerce is used.
Fan anteena provides the common solution to this problem.Fan anteena is that the spheric regions with 360 degree are divided into smaller area section, the antennas in two 180 degree, three 120 degree or four 90 degree zones for example.So the general main direction radiation towards particular section of fan anteena is to provide the radiation that focuses on more to specific geographical position.This concentrated radiation on specific direction improves the directive gain of antenna, makes antenna more effective.Yet there is shortcoming in the fan anteena of these standards.Each specific fan anteena only is designed and is configured to angle radiation with particular degree to cover predetermined zone.In case the fan anteena of standard is configured to satisfy these predetermined specifications, just can not be to this antenna correct.For example, fan anteena can be configured to its radiation is aimed at the angle of 45 degree to cover specific geographic area.As if changing application and need then going wrong to different zones or with different angle radiation.In this case, must be at the corresponding various different angular apertures design of different geographic regions and make a plurality of fan anteenas.Because each fan anteena only is suitable for specific situation, therefore be necessary to change the variation of antenna characteristics with response case.Therefore, need traditionally to change antenna or on electricity, revise existing antenna to deal with the variation of situation with the replacement fan anteena that is suitable for new situation.Owing to must make two independent antennas, replacing antenna has increased production cost, and requires to replace fully entire antenna.
In some cases, fan anteena can be revisable on electricity, or " intelligence ".Smart sector antenna can be used to attempt satisfying different parameters or standard.The such just smart antenna of switched beam antenna.Yet switched beam antenna produces a plurality of wave beams simultaneously, cause complicated and expensive more design, and a plurality of effective wave beam causes loss and poor efficiency.Usually, compare with the not reconfigurable fan anteena of standard, the bilateral antenna that is configured with revisable radio frequency (RF) switch on electricity that is used to control above-mentioned smart sector antenna has about 3 to 3.5dB losses owing to electronics reconfigures.This loss in many sensitive application is can not be received.Therefore, smart sector antenna is not because system complexity, cost and its intrinsic extra loss are feasible selection in many cases.
In addition, fan anteena is constructed to fixing polarized radiation.The polarization of antenna relates to electromagnetic wave in the direction of a distance, source from them.For example, electromagnetic wave may vertical orientated or horizontal alignment.Suitable polarization makes the antenna performance optimization, and obtains optimal results usually when the Polarization match of the polarization of transmitting antenna and reception antenna.The polarization of such antenna and directivity are embedded in the antenna radiator structure, and can not be changed.Therefore, when need be on a zone having problems during with a kind of unmatched polarized radiation signal of polarization of and fan anteena.In this case, the replacement of fan anteena and defective that it caused become unique feasible selection again.
