Abstract
The invention discloses a kind of miniaturization paster antenna, belong to wireless communication field.The antenna includes upper layer medium substrate, some parasitic patch of the radiation patch for being arranged at upper layer medium substrate front center position and the arrangement of four cycles, the resistance resistance to surface (RIS) and coaxial cable for being arranged at the upper layer medium substrate back side.The minimized wide-band paster antenna of the present invention, by introducing resistance resistance to surface (RIS) and coplanar parasitic paster simultaneously, there is good orientation consistency on the premise of guarantee bandwidth is very wide, also there is the advantages of miniaturization.
Description
Technical field
The invention belongs to wireless communication field, more particularly to a kind of miniaturization loading parasitic patch and resistance resistance to surface
Paster antenna.
Background technology
Paster antenna is due to having the advantages that small volume, in light weight, section is low, is easy to integrate with circuit and is made extensively
With.For paster antenna, it will usually in view of the situation on a certain platform, it is therefore desirable to which one obvious front and rear
Ratio is radiated farthest to reduce influence of the platform to antenna feed impedance and radiation characteristic.
Antenna cell design with obvious front to back ratio, metal-backed or high dielectric constant base can be used
Plate.Medium resonator antenna belongs to the latter, has wider bandwidth and higher gain, but this antenna cost of manufacture is not
Cheaply, and it is not easy to integrate with radio circuit；In addition, antenna may make day using dielectric or magnetizing mediums coating
Line integrally becomes heavy；For using metal-backed printed antenna, bandwidth and limited efficacy；It can be increased using air layer
Stick on the bandwidth of chip antenna, but if for the antenna of compact, we must use medium substrate；Some other
Method may also be used for improving the bandwidth of operation of antenna, including improves dielectric substrate thickness, introduced and posted with coplanar or stacking construction
Raw paster, being slotted by surface changes radiation patch type shape etc..
" being slotted by surface " method is very noticeable, because it is not only able to provide excellent bandwidth, and
With single layer radiation structure, the thin property characteristic of antenna is maintained.Typical example includes E types paster antenna, U grooves paster antenna, V
Groove paster antenna and ψ type paster antennas etc., but the disadvantage of these antenna is the orientation consistency under whole bandwidth of operation
It is not fine.
The content of the invention
For defect present in background technology, present invention design is a kind of to can be widely applied for the small of wireless communication field
Type wideband patch antenna, by introducing resistance resistance to surface (RIS) and coplanar parasitic paster simultaneously, before guarantee bandwidth is very wide
Put while there is good orientation consistency.
A kind of miniaturization paster antenna proposed by the present invention, including upper layer medium substrate, it is arranged at top dielectric base
The radiation patch of plate front center position and some parasitic patch of four cycles arrangement, it is arranged at the upper layer medium substrate back side
Resistance resistance to surface (RIS) and coaxial cable.The resistance resistance to surface includes layer dielectric substrate, is arranged at layer dielectric base
The square paster of plate front periodic arrangement and the metallic plate for covering layer dielectric substrate back.The inner conductor
It is welded in through two layer medium substrate in radiation patch.The radiation patch and parasitic patch are positive square paster.
The use of resistance resistance to surface makes antenna reach the purpose minimized, and parasitic patch is placed on radiation patch
Around, to improve impedance bandwidth and gain simultaneously.Inventive antenna -10dB impedance bandwidths are 2.42GHz to 3.18GHz, center
Frequency is 2.8GHz；Meanwhile gain is about 6.6-7.5dBi in whole operating frequency range, in whole working frequency range
(2.42-3.18GHz), the uniformity of radiation pattern are very good.
Inventive antenna can be widely applied for wireless communication field, and structure is compacter, antenna relative bandwidth reaches
27%, the gain of antenna reaches more than 6.6dBi, and directional diagram uniformity in whole working frequency range is very good, in summary this hair
It is bright to devise a kind of paster antenna of miniaturization.

Embodiment
Bandwidth and the gain of conventional patch antenna can be improved by using parasitic patch, enabled to using RIS surfaces
Antenna reaches the purpose of miniaturization.
As Fig. 1,2 be the present invention antenna structure, in addition to distributing point, whole antenna structure Central Symmetry.It is situated between including upper strata
Matter substrate (Rogers RT/duriod 5880) 4, it is arranged at the RIS surfaces at the back side of upper layer medium substrate 4, is printed in upper strata Jie
The square radiation patch 1 of the upper surface of matter substrate 4 and the evenly distributed 10 piece squares coplanar with square radiation patch 1 around it
Parasitic patch 2.Coaxial inner conductor 5 is welded in square radiation patch 1 through RIS surfaces with upper layer medium substrate 4.Specific chi
It is very little：Lgnd=64mm, W=24mm, F=2mm, C1=14mm, G1=1mm, h1=1.575mm.
Such as Fig. 3, Fig. 4 is RIS surfaces, is made up of periodic structure unit, the size and spacing of periodic structure unit are equal, whole
Individual structure is printed on the metallic plate 7 at the back side of layer dielectric substrate 6 by layer dielectric substrate (Rogers RT/duriod 6010) 6
