Abstract
The gain enhancement technology of dual-frequency dual-polarization and low-cost dual-polarization antenna based on the theory of high order mode is explored.Dual-frequency dual-polarization communication antenna adopts cross-shaped design,increases the side gain by adding short-circuit pin and superimposes the gain to achieve gain enhancement effect.It has the advantages of less multi-path fading and strong signal anti-interference ability,but it also has some limitations such as high cost and only suitable for narrowband communication system.On this basis,a low-cost dual-polarization communication antenna is designed,which still adopts the cruciform structure,and uses a lower-cost epoxy resin plate as the dielectric substrate,forming an air dielectric layer between the floor and the floor,and adding copper columns to improve the isolation.The experimental results show that the communication antenna has better gain enhancement effect and lower cost,and has the value of popularization and application.关键词
