The width in coupling gap is less than the 1/10 of the length of the parasitic patch.
Conventional microsthp patch antennas includes dielectric substrate, primary radiation patch, metal and coaxial feed.This practicality
It is novel on the basis of traditional micro-strip paster antenna, in two radiating sides (the long side axis of the radiation patch 8 of radiation patch 8
On line direction) parasitic patch is loaded respectively, by parasitic patch on the basis of the single resonant frequency that original radiation patch 8 determines
New high-frequency resonant frequency is introduced, by suitably adjusting the size of parasitic patch, can to realize between two resonant frequencies good
Good impedance matching.The impedance bandwidth of the micro-strip paster antenna will greatly increase as a result,.
Further, in above-mentioned micro-strip paster antenna, the parasitic patch 7 is rectangular, the long side ruler of the radiation patch 8
Very little 1.3 to 1.4 times for 7 length of side of the parasitic patch.
For conventional patch antenna, determine resonant frequency is the distance between two resonance sides, is in the present invention
8 long edge size of rectangular radiation patch:Long edge size is longer, and resonant frequency is lower.For square patch antenna, resonant frequency is determined
Be square size dimension.Therefore rectangular 7 length of side of parasitic patch should be less than intermediate rectangular patch long edge size, could be more

Gap 5, the second coupling 5 width of gap is 1/5 of the length less than the parasitic patch.
It should be noted that couple gap 6 for first between microband paste and parasitic patch, by emulation discovery, when the
When one coupling 6 size of gap is too small, the impedance matching of antenna is ineffective, and S parameter cannot be satisfied actual needs；With the first coupling
6 size of joint close gap becomes larger, and the impedance matching effect of antenna is become better and better；But when the first coupling gap 6 is oversized,
Although matching effect is more preferable, the bandwidth of entire antenna can be caused to narrow.Therefore the first and second coupling gaps should suitably be chosen
Size to design broad-band antenna.
Same mentality of designing is also applied for the identical second coupling gap 5 between each parasitic patch.Second coupling slot
Gap 5 mainly has an impact high-frequency resonant frequency caused by parasitic patch, as the second coupling 5 size of gap becomes larger, day
Matching effect of the line in high-frequency resonant frequency is obviously reinforced, while the beamwidth of antenna can be reduced slightly, therefore also to reasonably select
The size in the second coupling gap 5.

Other than generating certain influence to bandwidth, maximum effect is exactly the capacitance characteristic that balance parasitic patch is brought, metal in hole
Change through-hole and greatly strengthen the inductance characteristic of antenna, neutralizes the capacitive formed between antenna patch and patch and metal ground
Impedance realizes the steady high-gain of antenna so that the current distribution on each patch is more uniform.If it is logical not metallize
The gain flatness in hole, antenna has violent undulation.
Specifically, in above-mentioned micro-strip paster antenna, the diameter of the plated-through hole 3 is less than the parasitic patch
The 1/5 of length.The size for adjusting plated-through hole, can optimize the current distribution on each patch, realize that the high-gain of antenna is special
Property.
In above-mentioned micro-strip paster antenna, the coaxial feed conductor needle 4 is set along the long axis direction of the radiation patch 8
It sets, the center of the coaxial feed conductor needle 4, which meets to input under operating frequency of antenna with the centre distance of the radiation patch 8, to be hindered
Anti- matching requirement.The coaxial line structure of the utility model feed needs to adjust the distance at its 8 center of radiation patch, it is made to meet
With 50 ohm of input impedance characteristic under working frequency.

Side is penetrated to external radiation, is coupled in parasitic patch adjacent thereto by the first coupling gap 6 of two radiating sides, then pasted by parasitism
The second coupling gap 5 between piece is coupled in other parasitic patch, is allowed to generate resonance, final each patch in higher frequency
Energy is effectively radiated in free space.By the size of adjusting parasitic patch, microband paste and parasitism paste the present embodiment
The gap size between gap size and each parasitic patch between piece, the impedance matching for being allowed to meet under design frequency are wanted
It asks, new mode of resonance can be generated in higher frequency, more efficiently broaden the bandwidth of antenna；In addition, being posted by adjusting
The size of cylindrical metal through-hole between raw patch and metal ground, can optimize the current distribution on patch, enhance antenna
Inductance characteristic so that current distribution is more uniform on each patch, keeps radianting capacity stronger, to effectively improve the increasing of antenna
Benefit.Since antenna uses the paster structure of single layer to be designed completely, without increasing the thickness or level of dielectric substrate, plane
