The invention relates to a two-channel wideband antenna which is characterized in that the two-channel wideband antenna mainly comprises a reflection plate, radiation units and wireless separation components, the two sides of the reflection plate are bent to form a reflection wall which is bent outwards repeatedly, the repeated-bent reflection wall comprises a first reflection wall unit, a second reflection wall unit and a third reflection wall unit from the center to the two sides of the reflection plate, an auxiliary reflection wall unit is arranged on the outer side of the third reflection wall unit, the reflection plate is provided with 12 radiation units in the long axial direction of the reflection plate, the radiation units are PCB printing oscillators, and the wireless separation components are arranged between the first radiation unit and the second radiation unit and between the second radiation unit and the third radiation unit. The two-channel wideband antenna has the advantages that the reflection plate with a plurality of reflection faces and the PCB printing oscillators are matched to form the two-channel wideband antenna, performance requirements in the work frequencies of 1710-1850MHz, 1880-1920MHz, 2010-2025MHz and 2555-2635HMz can be met, a DSC1800 system and a TDD system can be covered, the application range is wide, and communication quality is high.
Description
technical field [0001] The invention relates to an antenna, in particular to a dual-channel broadband antenna. Background technique [0002] In the cellular mobile communication system, the antenna is the converter of the circuit signal of the communication equipment and the space radiation electromagnetic wave, and is the bridgehead of the space wireless communication. Therefore, the base station antenna is an important part of the mobile communication system, and its characteristics directly affect the overall performance of the entire wireless network. . [0003] With the continuous advancement of science and technology, the field of wireless communication is also undergoing tremendous changes. In the traditional limited frequency domain, it has been unable to meet people's increasing needs. It is an imminent fact to broaden the use of frequency bands. Antennas are an indispensable component in wireless communication systems, and the research on broadband and ultra-wideb...
