Description
Technical field
The present invention relates to a kind of microstrip slot antennas, and in particular to a kind of new-type groove type super wide band microstrip slot antenna.
Background technique
Microstrip antenna has the shortcomings that its intrinsic-impedance bandwidth is narrow, this has seriously affected it as a kind of resonant aerial
In the extensive use of microwave regime.With the rapid development of mobile communication, requirement of the communication system to the beamwidth of antenna is higher and higher,
Especially 2 months 2002 FCC (US Federal Communication Committee) 3.1~10.6GHz frequency range is incorporated into the civilian frequency for ultra wide band
Duan Hou, ultra-wideband antenna are increasingly becoming research hotspot, therefore, broaden the bandwidth of microstrip antenna to UWB frequency range have it is particularly significant
Meaning.
In general improve antenna bandwidth have following three kinds of methods: 1) gradual change impedance thought: because signal impedance not
Continuous place is reflected, therefore the main points of impedance matching are that impedance is altered in steps along transmission line, to reduce as far as possible
Reflection；2) antenna array is designed, passes through feeding network between each separate antennas, intercouples and broaden bandwidth；3) feed method is improved.This
Several method generally changes antenna structure, and comparison is complicated, also will increase the size of antenna, not easy of integration.For above
Problem, microstrip slot antenna are devised, and microstrip slot antenna is low to requirement on machining accuracy, can use the photoetching skill of standard
Art is produced on deposited copper circuit board, and working band is wider, is widely used in modern radar, electronic countermeasure and wireless communication etc.
The design of field broad-band antenna.It can be presented by microstrip line or co-planar waveguide (Coplanar Waveguide, CPW)
Electricity has the bandwidth more relatively broader than microstrip antenna, can be used for the design of ultra-wideband antenna.
Summary of the invention
In order to solve the problems in the existing technology, the present invention provides a kind of new-type groove type super wide band microstrip gap day
Line solves the problems such as ultra-wideband antenna production common in the prior art is complicated, size is larger.
The technical solution of the present invention is as follows:
A kind of new-type groove type super wide band microstrip slot antenna, including medium substrate and metal ground plate, the medium base
The back side of plate is provided with metal ground plate；The positive lower right of medium substrate is provided with incoming feeder；Metal ground plate is outputed recessed
Groove profile gap is subtracted each other to obtain by rectangle and 1/2 circle.
The medium substrate is FR4 material, and dielectric constant 4.4, being lost is 10-5。
Length × width × height=55 × 55 of the medium substrate × 1.5mm.
The incoming feeder is the microstrip line that characteristic impedance is 50 ohm, is feed microstrip line structure.
The side length in the groove type gap is 43mm, is that 1/2 radius is subtracted on the rectangle of 43mm is 21.5mm's by side length
Circle completes.
The invention has the advantages that:
1. the present invention reduces day using the method for outputing groove type gap on earth plate, the bandwidth of Lai Tuokuan antenna
The size of line, the bandwidth of antenna reach 182% (frequency range 2.2GHZ-8.4GHZ).
2. present invention gain in frequency range is higher, and realizes inhibition to WLAN narrowband systems.
3. micro band superwide band antenna structure of the invention is simple, easy to process.
