Abstract

The invention discloses a circular patch microstrip antenna. The circular patch microstrip antenna comprises a first dielectric plate and a second dielectric plate which are arranged up and down, wherein supporting rods are arranged between the first dielectric plate and the second dielectric plate in a supporting manner; a circular radiation patch is formed on the upper surface of the first dielectric plate; two arc-shaped first gaps are symmetrically formed in the radiation patch in a first direction; two arc-shaped second gaps are symmetrically formed in the radiation patch in a second direction; the first direction is perpendicular to the second direction; a grounding part is formed on the lower surface of the second dielectric plate; and a coaxial probe is connected between the radiation patch and the grounding part. According to the circular patch microstrip antenna, the bandwidth is effectively increased; and in addition, the patch is small in area while the in-band gain is relatively stable.

Description

technical field [0001] The application belongs to the technical field of wireless communication, and in particular relates to a circular patch microstrip antenna. Background technique [0002] Printed circuit board, dipole antennas, while all good functional antennas, tend to operate at relatively narrow bandwidths. The narrow operating bandwidth limits the application of printed circuit boards, dipole antennas to devices required to operate over large bandwidths such as the IEEE802.11a band. [0003] In view of this, it is necessary to provide a new type of planar antenna. Contents of the invention [0004] The object of the present invention is to provide a circular patch microstrip antenna to overcome the deficiencies in the prior art. [0005] To achieve the above object, the present invention provides the following technical solutions: [0006] The embodiment of the present application discloses a circular patch microstrip antenna, which includes a first dielectric...
