Abstract

The invention discloses a patch antenna and a patch antenna manufacturing method, which relate to the field of communication, and are used to solve the problem that the adoption of a dual-polarized antenna results in low PCB space utilization rate. The patch antenna comprises a first patch antenna array and a second patch antenna array. The first patch antenna array comprises M first patch dipoles and a first feed network. The second patch antenna array comprises N second patch dipoles and a second feed network. The M first patch dipoles and the N second patch dipoles share L patch dipoles. The adjacent patch dipoles belonging to the same patch antenna array are electrically connected with one another. The first feed network is electrically connected with the first patch dipoles along a first polarization direction, the second feed network is electrically connected with the second patch dipoles along a second polarization direction, and the first polarization direction is different from the second polarization direction. The embodiment of the invention is applied to the design of a dual-polarized patch antenna.

Description

technical field [0001] The present invention relates to the communication field, in particular to a patch antenna and a method for manufacturing the patch antenna. Background technique [0002] In the field of wireless communication, as the user environment becomes more complex, users have higher and higher requirements on the transmission rate. In this case, the requirement for the antenna is to provide a sufficiently high gain while satisfying the bandwidth. [0003] There are many ways to achieve high gain in antenna design, one of which is to use patch arrays. A patch array refers to an array composed of multiple patch antennas. The greater the number of patch arrays, the greater the antenna gain achieved. Such as figure 1 Shown is a polarized patch array composed of four patches, including patch 01, feed network 02, and feed point 03. However, dual-polarized antennas are generally used to transmit data in wireless communication systems to reduce the correlation betwe...
