Description

Technical Field

[0001] The utility model relates to the technical field of combined patch antennas, in particular to a printed circuit board processing and leveling device. Background Art

[0002] A patch antenna is a pancake-shaped directional antenna consisting of two metal plates, one of which is larger than the other, stacked together with a sheet of dielectric in the middle. It is usually installed in white or black plastic to protect the antenna and facilitate installation. The patch antenna is flat, thin and lightweight, so it can be easily hung on a wall or ceiling. Its propagation range is between 30 degrees and 180 degrees, forming a hemispherical coverage area. It is suitable for covering single-story small offices, small stores and other indoor locations where access points cannot be placed in the center.

[0003] Patch antennas are widely used in wireless communications, radar, electronic countermeasures and other fields. With the advancement of technology and the expansion of application fields, their development prospects are very broad.

[0004] However, the structure of existing patch antennas is relatively simple. Due to its small size, a single patch antenna will have a relatively narrow bandwidth, large dielectric loss, and small power capacity.
