Abstract
The utility model discloses a paraboloid dual-polarized antenna for microwave communication, which comprises a feed source coupling flange and a single-polarization exciter connected through a first waveguide. The antenna is characterized in that a second waveguide parallel to the first waveguide is further connected between the feed source coupling flange and the single-polarization exciter, so as to form a dual-polarized feed source. The dual-polarized antenna provided by the utility model has identical occupied space as the single-polarized antenna; the cost for frequency backup is lower than that for adopting two antennas; and the maintenance cost is relatively lower.
Description
Technical field
The utility model belongs to the product scope of microwave antenna, relates to a kind of microwave antenna, particularly a kind of dual polarized antenna that backs up usefulness fully frequently of microwave communication parabolic antenna.
Background technology
Microwave communication is one of wireless communication means commonly used in the world at present, and it is widely used in fields such as transfer of data, radio and television transmission, mobile communication base station signal contact.Along with improving constantly of communications band, also more and more higher to the backup request of frequency fully of link.Adopting suitable antenna technology will be to control coverage effectively, reduce one of method of co-channel interference and the reception of improving mobile phone signal.Traditional backup means are to set up the two sides single-polarized antenna at same website, its product structure schematic diagram is referring to Fig. 1, comprise feed terminal pad 1 and the single polarization exciter 2 that is connected by waveguide 3, this product is a kind of single-polarized antenna that can only the transmission of one line signal, the shortcoming of this method is to consider the installation question that sets up of antenna, often owing to antenna installation mounting condition (need to build iron tower and enlarge antenna platform) does not possess and abandoned best site.The two surface antenna expenses of setting up simultaneously are higher, and maintenance cost is bigger than normal, and it is too many to take volumetric spaces.
Summary of the invention
Carry out circuit with the two sides single-polarized antenna and be equipped with the deficiency that backup frequently exists at above-mentioned, the purpose of this utility model is to provide a kind of convenient, practicality and the moderate microwave communication parabolic antenna of cost that microwave circuit is equipped with frequently and backs up.
In order to realize above-mentioned task, of the present utility modelly take following technical solution:
The parabolic dual polarized antenna of a kind of microwave communication, comprise feed terminal pad and single polarization exciter, excitation is connected by first waveguide feed terminal pad with single polarization, it is characterized in that, between described feed terminal pad and single polarization exciter, also be connected with second waveguide, this second waveguide and first waveguide be arranged in parallel, form bipolar feed source.
Described first waveguide and the second waveguide cross section are rectangle.
The parabolic dual polarized antenna of microwave of the present utility model, the phase ratio antenna, the volume that takies is identical, but has constituted dual polarized antenna, and it is equipped with when frequently backing up than using the with low cost of two single-polarized antennas, the corresponding minimizing of maintenance cost.
Description of drawings
Fig. 1 is the original product structural representation.
Fig. 2 is a structure chart of the present utility model.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Embodiment
Referring to accompanying drawing 2, the parabolic dual polarized antenna of microwave communication of the present utility model, mainly be that core to microwave antenna is that feed partly carries out complementary design, promptly on the original product architecture basics, the waveguide 3 between single polarization exciter 2 and the feed terminal pad 1 is changed slightly, add a waveguide 4 that be arranged in parallel with waveguide 3 simultaneously, form bipolar feed source, make a kind of feed can transmitting two paths of signals, simultaneously and the supporting use of respective reflective surfaces, form a kind of brand-new dual polarized antenna.
The cross section of described two waveguides 3,4 is a rectangle, and the distance between two waveguides 3,4 is according to the standard setting.
The parabolic dual polarized antenna of microwave communication of the present utility model, plan is applied on the microwave antenna of 0.9 meter, 1.2 meters, 1.8 meters, 2.0 meters, 2.4 meters, 2.5 meters, 3.0 meters, 3.2 meters and 4.0 meters, the result proves by experiment, need not during application that hardware is made in the base station and changes.Be equally applicable on the antenna of other bores or similar structures.
Claims (2)
