The utility model discloses a structure has higher bandwidth and gain.

Description

A kind of L-type probe microstrip antenna

Technical field

The application belongs to wireless communication technology field, particularly relates to a kind of L-type probe microstrip antenna.

Background technology

Although printed circuit board (PCB), dipole antenna are all good function antennas, tend to relatively narrow bandwidth operation.Narrow bandwidth of operation limits printed circuit board (PCB), dipole antenna on the large broadband of such as IEEE802.11a frequency band, operates application on required equipment.

In view of this, the flat plane antenna that a kind of high bandwidth is provided is necessary.

Utility model content

The purpose of this utility model is to provide a kind of L-type probe microstrip antenna, to overcome deficiency of the prior art.

For achieving the above object, the utility model provides following technical scheme:

The embodiment of the present application discloses a kind of L-type probe microstrip antenna, comprise first medium layer setting up and down and second dielectric layer, bracing or strutting arrangement is provided with between described first medium layer and second dielectric layer, described first medium layer and second dielectric layer interval are arranged, the lower surface of described first medium layer is formed with radiation patch, the upper surface of described second dielectric layer is provided with L-type probe, described radiation patch offers the gap of rectangle.

Preferably, in above-mentioned L-type probe microstrip antenna, described radiation patch is rectangle.

Preferably, in above-mentioned L-type probe microstrip antenna, described gap extends along the diagonal of described radiation patch.

Preferably, in above-mentioned L-type probe microstrip antenna, the material of described first medium layer and second dielectric layer is polytetrafluoroethylene.

Compared with prior art, the utility model has the advantage of: structure of the present utility model has higher bandwidth sum gain.
