Technical field
The present invention relates to Orthogonal Double slot type wideband omnidirectional circular polarisation printed antenna, belong to telecommunication technology field.
Background technology
With the development of wireless communication technology, the requirement that people carry out efficient communication whenever and wherever possible to mobile terminal is also increasingly
Rise, this just puts forward higher requirement to the performance of its antenna.Have benefited from the development of relaying technique and increasing of base station number,
For the antenna in wireless communication system, most of mobile terminal antennas are required to it and have omnidirectional radiation characteristic, because
So can keep carrying out real-time Communication for Power with surrounding devices.Circular polarized antenna can effectively receive any polarization incoming wave, prevents pole
Change mismatch it is ensured that receiving and dispatching the stability of transmission.It is narrower to there is frequency band in existing circular polarized antenna, and the larger grade of gain smaller size smaller lacks
Point.
Content of the invention
For solving technical problem present in above-mentioned prior art, it is complete that the present invention proposes a kind of Orthogonal Double slot type broadband
To circular polarisation printed antenna, the technical scheme taken is as follows：Due to ring gap, vertical metal tape and rectangular aperture
Exist, define the ring current distribution of identical rotation direction in top layer and bottom metal layer.Because upper and lower two electric current loops are for xoy
