Technical field
The utility model belongs to microstrip antenna technical field, and it is micro- specifically to design a kind of dual polarization based on L-type probe feed
Band paster antenna.
Background technology
In recent years, with a large amount of uses of mobile device, microstrip antenna is increasingly favored by every experts and scholars,
And in aerospace, the fields such as military affairs are widely used.But the requirement with people for mobile communication equipment
Higher and higher, microstrip antenna receives many limitations in use, and volume is big, and frequency bandwidth is narrow, and low income is current
The main problem of microstrip antenna.In addition, mobile communication equipment develops towards miniaturization and the direction of portability always, this is just more
The requirement added, microstrip antenna will be towards small, and light-weight, the direction of high-gain is developed.And we generally consider the ginseng of antenna
Number is its reflectance factor and isolation, it is considered that when frequency is 5GHz, reflectance factor can reach -15dB, and
When the signal emitted between two probe feeds is more than half wavelength, it is believed that correlation is low between antenna feed, isolation
Height can be very good work.But by the way of most of present antenna is fed using single polarization edge, although this can be reduced
The volume of antenna reduces the occupied space of equipment, but its reflectance factor is relatively low, and narrower bandwidth, radiation efficiency is relatively low, to shadow
Ring communication quality.So using L-type probe feed so far, and frequency bandwidth is widened using dual polarization feeding classification, reduced
Antenna volume improves one of the hot issue that gain effect is current Antenna Design.Therefore, it is presented using L-type probe and dual polarization
The mode of electricity, which becomes, widens frequency band, realizes a kind of effective method of miniaturization.
Invention content
The purpose of this utility model is that propose a kind of design scheme of novel microstrip antenna, using L-type probe and double
Polarize the mode fed, and the dual polarized microstrip patch antenna of the L-type probe feed can effectively widen the frequency band of antenna, contract
The volume of miniature antenna promotes the isolation of antenna, to significantly improve the income of antenna.
The realization process of the utility model is as follows：
A kind of dual polarized microstrip patch antenna based on L-type probe feed, structure include dielectric-slab, radiation patch, L-type
Probe feed, earth plate, upper layer reflecting plate reflect patch.It is characterized in that：The reflection patch tightly be attached to upper layer
On reflecting plate, between upper layer reflecting plate and the dielectric-slab of lower layer at a distance, plastics screw is used in combination to be fixed on Jie of lower layer
On scutum；The radiation patch being attached on dielectric-slab tightly, dielectric-slab is tightly attached to the upper surface of earth plate, earth plate and Jie
Clip the horizontal patch of two L-type probes between scutum, the inner core of the L-type probe tightly on horizontal patch, and
It is extended downwardly across earth plate, outer core being wrapped on inner core tightly.
A kind of dual polarized microstrip patch antenna based on L-type probe feed, it is characterised in that：Dielectric-slab, upper layer
Reflecting plate, the outer core of L-type probe feed vertical component are Rogers materials, radiation patch, L-type probe vertical component inner core and
Horizontal patch reflects patch, and earth plate is copper product.
Compared with prior art, advantageous effect is the utility model：
The utility model uses the dual polarization feed structure of L-type probe, not only so that antenna is easy for installation, and meets antenna
Requirement for miniaturization；Importantly, the dual-polarized feeding classification using L-type probe can effectively raise antenna
Frequency bandwidth so that the transmission of signal more stablize, to improve the communication quality of antenna.In addition to this, this practicality is new
Type also helps the Integrated design of antenna array.
