Description
Technical field
The utility model relates to antenna equipment technical fields, and in particular to a bulb frame-shaped microstrip antenna and communication device.
Background technique
At present in wireless communication technology field, there are two ways to realizing multifrequency: one is using ultra-wideband antenna by institute
There is frequency range all to cover, but this method is suitable only for multiple frequency ranges at a distance of closer situation, there is significant limitation；Separately
A kind of method is that the mutiple antennas in system is allowed independently to cover these frequency ranges, and the method is relatively common, but is existed very much
Technological difficulties, such as the problem that interferes with each other between antenna element, and occupied space is larger.So it is desirable in single antenna
Upper realization double frequency or multifrequency, to avoid the problem that interfering with each other between antenna.
Currently, realizing multifrequency on single antenna, small in size, light weight, purpose easy of integration are actually reached.But it is single more
