Description
Technical field
The utility model relates to a kind of directional antenna, relates in particular to a kind of Miniature RF directional antenna used for intelligent electric network.
Background technology
In the monitoring systems such as intelligent grid, need radio frequency read-write system antenna, thereby read the wireless signal of wireless senser.In intelligent grid converting equipment place, because sensing point is many, and single antenna is held sensor signal Limited Number, the many antenna receiving signals of all common employings, i.e. a specific sensor signal of antenna reception.
Due to converting equipment near distance, the omnidirectional antenna of single same frequency band will receive the sensor signal of other antenna cover, forms to intersect to disturb.Because directional antenna has the feature that particular space points to, therefore directional antenna can effectively prevent the signal cross-talk between many antennas.As another one contradiction, the common volume of directional antenna is large, easily forms partial discharge phenomenon in the strong-electromagnetic field of high-tension electricity.Therefore the directional antenna that volume is little becomes crucial difficult point.
In existing directional antenna technique, relate generally to the application of directional antenna, utilize reflector, symmetrical dipole etc. to reach object simple in structure, shortcoming is directionality deficiency.And the application of the directional antenna that prior art relates to, utilizes the different refraction index profile of super material panel to meet different focal needs, size is larger, easily forms partial discharge phenomenon in intelligent grid.
Therefore, there is defect in prior art, needs further improvement and development.
