Problems solved by technology

The low-frequency vibrator in the existing solution often adopts an all-metal or all-dielectric plate structure, resulting in a larger antenna size, which leads to a serious shielding phenomenon with the high-frequency vibrator, thereby increasing the interference with the high-frequency vibrator

Abstract

The invention discloses a low profile cross-shaped vibrator for a multi-frequency base station antenna. The vibrator comprises a horizontal feed medium plate, two vertical feed medium plates and fourantenna vibrator arms. The two vertical feed medium plates are respectively a -45 DEG vertical feed medium plate and +45 DEG vertical feed medium plate. Two sides of the upper ends of the two verticalfeed medium plates are respectively provided with a notch matched with the vibrator arm. An end portion of an end of each antenna vibrator arm has a channel matched with thickness of the vertical feed medium plate. One end of the antenna vibrator arm is clamped in the notch of the vertical feed medium plate, and the notch of the vertical feed medium plate is also clamped in a channel on the end of the antenna vibrator arm. A microstrip circuit is disposed on the front surface of the horizontal feed medium plate. The horizontal feed medium plate has a cross-shaped groove matched with the two vertical feed medium plates. The cross section of a radiation arm of the vibrator is relatively small, and blocking of a high frequency vibrator can be effectively reduced, thereby reducing interference to the high frequency vibrator.

Description

technical field [0001] The invention relates to a vibrator, in particular to a low-profile cross-shaped vibrator used for multi-frequency base station antennas. Background technique [0002] With the development of mobile communication technology, people have higher and higher requirements on the communication rate, so the deployment and application of wireless communication systems in different frequency bands are increasing, resulting in more and more limited space on communication towers. In order to effectively reduce the installation space of the antenna on the iron tower, it is necessary to develop a multi-frequency antenna. However, integrating antenna elements of multiple frequency bands in a limited antenna space will bring great difficulties to antenna design, such as interference between antenna elements of different frequency bands. In order to effectively reduce the interference between antenna dipoles in different frequency bands, it is an effective way to des...
