Description

Technical Field

[0002] The existing single-fed laminated ceramic antenna is a laminated antenna that is small on the top and large on the bottom, which is formed by encapsulating several ceramic antennas of different sizes together through media such as double-sided tape or solder paste. The effective space utilization rate of this type of laminated ceramic antenna is low when in use, and it is not convenient to install and fix. If the double-sided tape has poor viscosity or fails due to aging, the upper layer and the lower layer of the antenna are easy to rotate relative to each other around the feeding copper needle, which will affect the impedance of the antenna and cause the antenna to produce frequency deviation, resulting in the product being unable to be used normally, which is not conducive to subsequent adjustment, replacement or maintenance, and cannot meet the use requirements. Therefore, a single-fed laminated ceramic antenna that is easy to adjust is proposed to solve the above-mentioned problems. Utility Model Content
