Along with the fast development of wireless communication technology, also more and more higher to the requirement of antenna, as miniaturized, lightweight, low section, be convenient to a series of requirements such as integrated, microstrip antenna has attracted the attention of numerous scholar because of the advantage of its uniqueness, the beamwidth of conventional microstrip antenna is narrower, needs to have in the application of high noise immunity, polarizers of big angle scope scan capability not competent at some.Simultaneously, increase coverage can to improve in building and high-speed motion time signal receiving quality, and the beamwidth of common microstrip antenna is generally at 70 ° ~ about 110 °, when the low elevation angle, (elevation angle is 10 °) gain, between-7dB ~-3dB, therefore realizes above-mentioned requirements with common microstrip antenna very difficult.
utility model content:
Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, provides that a kind of beamwidth coverage is large, structure is simple, small volume, gain are higher and be easy to the modified form wide-beam circularly-polarizedmicrostrip microstrip antenna that realizes.
The technical solution of the utility model is:
A kind of modified form wide-beam circularly-polarizedmicrostrip microstrip antenna, comprise ground plate and conductor patch, single-point coaxial feeding is provided with between described ground plate and conductor patch, and the coaxial cable of described coaxial feeding is placed in the below of described ground plate, between described ground plate and conductor patch, be provided with gap.
The lower end of described ground plate is provided with pyramid-type horn mouth housing, and the small end of described horn mouth housing is connected with described ground plate.
The small end of described horn mouth housing is provided with horizontal flanging, between described horizontal flanging and described ground plate for bond fix or bolt be connected and fixed.
The lower surface of described ground plate is provided with groove, and the centre of described groove is provided with through hole.Described coaxial cable is fixedly connected with conductor patch with screw by fixed head.
The beneficial effects of the utility model are:
1, the utility model is reduced before and after antenna by the reflex of ground plate and goes back broadening wave beam while ratio, solve the problem that conventional microstrip antennas wave beam is narrow preferably, and broad beam can be formed in E face and H face, effectively improve the quick access capability of GPS.
2, the utility model adopts single-point feedback, and any desired location that distributing point can be selected in conductor patch is convenient to coupling, and single feed point circular polarization microstrip antenna is because it is without the need to additional phase-shift network and power divider, and compact structure is more suitable for the miniaturization of antenna.
3, the utility model adopts coaxial feeding, and coaxial cable is placed in the below of ground plate, avoids the impact on aerial radiation.
4, the utility model microstrip antenna positioned beneath pyramid loudspeaker structure of slotting at ground plate, due to pyramid loudspeaker structure, the return loss, standing wave when impedance etc. of antenna can be greatly affected, can on the basis of the microstrip antenna of ground plate fluting, finely tune, due to the reflex of pyramid loudspeaker structure, the back lobe of the directional diagram of antenna can be reduced, broadening antenna beamwidth.
5, the utility model can be applied in the equipment of various outfit GPS navigation receiver, as vehicle-mounted GPS navigator, boat-carrying GPS navigation receiver etc., many-side, multi-level service, technology transfer and product promotion can be provided to apply for many enterprises, realize good economic benefit.
