The microstrip antenna comprises a bottom plate, a baseplate and a radiation plate, wherein the baseplate is arranged above the bottom plate, the radiation plate is arranged above the baseplate, an H-shaped groove and a feed point are arranged on the radiation plate, a connector is connected between the bottom plate and the radiation plate, and the connector is connected with the feed point. The radiation plate in the microstrip antenna can reduce the resonance frequency of the antenna and be easy to realize the properties of circular polarization and double-frequency dual-polarization on the premise of ensuring a certain gain and bandwidth, and has the advantages of simple structure, capability of reducing the volume of the antenna, lighter weight and convenience in processing.
Description
Technical field
The utility model relates to field of antenna, particularly relates to a kind of microstrip antenna.
Background technology
The transmission mode of bluetooth is to be the basis with a piconet, can have slave unit and aggressive device of seven bluetooths in piconet simultaneously, and the frequency hop sequences of all slave units must be worked in coordination with aggressive device in same piconet.Under the basis of piconet, can allow single-point to single-point, single-point to multiple spot and several piconets multiple transmission mode of link mutually.In above these patterns; No matter be active or the slave unit in the piconet; Because all need with net in change the position at any time driven or aggressive device get in touch; So these install employed aerial radiation field pattern must be approximate isotropic, transmit or receive if use the too high antenna of directive property to do, will cause two signals between the blue-tooth device on some relative angle, can't normally transmit.Present modal Bluetooth antenna kind comprises: microstrip antenna, dipole antenna and PIFA antenna.Because these antenna has approximate isotropic radiation pattern and advantage simple in structure, that cost of manufacture is low, so be fit to very much the use of blue-tooth device.
Because microstrip antenna only need utilize metallic conductor to cooperate the suitable base plate that is fed into ground plane, so its cost of manufacture is low, and can be directly and the PCB circuit board weld together.The metallic conductor of microstrip antenna can use wire or sheet, is welded on the purpose that reaches conceal antenna on the circuit board if then can be designed to the SMD assembly with Metal Flake making.With grounding metal plane do not produce short circuit for the support metal sheet this moment; The medium that can between sheet metal and ground plane, add insulation usually; If the size that the higher insulation material of working medium constant can also be dwindled Bluetooth antenna; But normally take plastic stent to come the support metal sheet, the dielectric constant between antenna and the grounding metal plane just is equivalent to the dielectric constant of air at this moment.But the method that finally reduces antenna area in the prior art through reducing antenna resonant frequency is less.
The utility model content
The technical problem that the utility model mainly solves provides a kind of simple in structure, easy to process, weight reduction, the less microstrip antenna of volume.
For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: a kind of microstrip antenna is provided, comprises base plate, substrate and radiant panel, said substrate is arranged on the base plate top; Said radiant panel is arranged on the substrate top; Radiant panel is provided with H shape groove and distributing point, is connected with connector between said base plate and the radiant panel, and said connector is connected with distributing point.
In preferred embodiment of the utility model, be provided with insulating barrier between said base plate and the substrate.
In preferred embodiment of the utility model, be connected through screw respectively between said base plate and insulating barrier, insulating barrier and the substrate.
In preferred embodiment of the utility model, said radiant panel is a sheet metal.
In preferred embodiment of the utility model, said H type groove is arranged on the radiant panel center, and said distributing point is arranged on H type groove one side.
In preferred embodiment of the utility model, said radiant panel is fixedly connected with substrate through screw.
In preferred embodiment of the utility model, said radiant panel is square.
The beneficial effect of the utility model is: the radiant panel in the utility model microstrip antenna has reduced the resonance frequency of antenna; Under the prerequisite of guaranteeing certain gain and bandwidth; Be easy to realize circular polarization and dual-band and dual-polarization characteristic, simple in structure, reduced antenna volume; Weight is lighter, and is easy to process.
Description of drawings
