Problems solved by technology

[0003] For commonly used PCB antennas, microstrip methods, monopoles, dipoles, and coplanar waveguides are usually used. For microstrip antennas, the relative bandwidth of monopoles is relatively narrow, about 5%, usually by forming an array antenna or Increase the bandwidth by increasing the thickness of the medium, but for the frequency band with a long signal wavelength, the increase in the number of oscilla...

Abstract

The invention discloses a microstrip antenna. The microstrip antenna comprises a substrate, a reference stratum disposed at the back surface of the substrate, and folding antenna dipole arrays disposed at the front surface of the substrate. The folding antenna dipole arrays comprise: a first antenna array and a second antenna array which are connected in series for feeding through an inter-array impedance transformation line, wherein the first antenna array comprises a first folding dipole and a first impedance transformation line connected with the first folding dipole; the second antenna comprises a second folding dipole and a second impedance transformation line connected with the second folding dipole; the second impedance transformation line is connected with the inter-array impedance transformation line, and the first impedance transformation line is connected with the inter-array impedance transformation line; and the end, which is back from the second antenna array, of the first impedance transformation line is connected with a first feed microstrip line. According to the invention, the two folding antenna dipole arrays connected in series for feeding are employed, such that the antenna width is reduced, the gain of the antenna is improved, omnidirectional performance of the antenna is maintained, and the obtained standing wave bandwidth is quite wide.

Description

technical field [0001] The invention relates to the communication field, in particular to a microstrip antenna. Background technique [0002] At present, wireless communication technology is developing rapidly. As an indispensable component in the communication industry, antennas are constantly developing towards miniaturization, multi-frequency and broadband in order to meet the needs of various data services. [0003] For commonly used PCB antennas, microstrip methods, monopoles, dipoles, and coplanar waveguides are usually used. For microstrip antennas, the relative bandwidth of monopoles is relatively narrow, about 5%, usually by forming an array antenna or Increase the bandwidth by increasing the thickness of the medium, but for the frequency band with a long signal wavelength, the increase in the number of oscillators will lead to an increase in the volume of the antenna, which is not conducive to the miniaturization of the antenna. Monopole PCB antennas and ordinary d...
