Description
Technical field
The communications field is the utility model is related to, more particularly to a kind of antenna.
Background technology
With the fast development of wireless communication technology, the requirement more and more higher for wireless system equipment, especially to energy
The demand for being operated in apparatus for multiple band communication simultaneously increasingly increases.Antenna is as important hardware composition portion in Wireless Telecom Equipment
Point, the important task that electromagnetic wave was penetrated and received to good fortune is carry, therefore the quality of antenna performance directly determines the workability of communication system
The quality of energy.
With the development of the communication technology, communication equipment generally requires to be operated in the new work(that different frequency band realizations emerges in an endless stream
Can, therefore come it is generally necessary to use multiple antennas in a communication system while realize multiband operation.It is it is well known that existing
Some communication equipment finite volumes, and increasingly develop towards the mode of miniaturization, the cloth of multiple antennas on a communications device
Office and interfere with each other referred to as very stubborn problem, therefore the application of multiband antenna also just seems extremely important.Tradition back of the body chamber
Slot antenna volume is big, heavier mass, structure are complex, it is impossible to meets requirement of the people to antenna performance and size, greatly
The application for limiting antenna.
Utility model content
In order to solve the above problems, the utility model provides a kind of circular patch microstrip antenna.
The utility model in order to solve its technical problem used by technical scheme be：A kind of circular patch microstrip antenna,
It is made up of bottom surface, dielectric substrate, half of rectangular cavity, 1 opening, feed probes, 1 short circuit pin.The dielectric substrate is
Rectangular parallelepiped structure, material are leather substance.Bottom surface is rectangular configuration, positioned at Jie's substrate bottom, has good electric conductivity.Half
The resonator that individual rectangular cavity is made up of 5 faces such as the rectangle positioned at dielectric substrate roof, corresponding bottom surface, 3 side walls,
Rectangle, 3 side walls positioned at dielectric substrate upper surface are respectively provided with good electric conductivity.1 opening is located at half of rectangle resonance
The side of chamber, close to dielectric substrate center.Increase a diameter of 1mm connection cavity roofs and the short circuit pin of bottom surface in resonator,
When short circuit pin is close to cavities open or side wall, the anti-matching of antenna is optimal.
