摘要：A dual band high isolation antenna structure includes a diplexer unit, a 4-port decoupling module, a first frequency band antenna assembly, and a second frequency band antenna assembly. The diplexer unit is operable to frequency domain multiplex between a first frequency band and a second frequency band. The 4-port decoupling module is operably coupled to the diplexer unit and is operable to isolate a first pair of ports from a second pair of ports. The first frequency band antenna assembly is operably coupled to the diplexer unit and is operable to transceive wireless signals in the first frequency band. The second frequency band antenna assembly is operably coupled to a port in each of the first and second pairs of ports and is operable to transceive wireless signals in the second frequency band.

主权项：1. A dual band high isolation antenna structure comprises: a diplexer unit for frequency domain multiplexing between a first frequency band and a second frequency band; a 4-port decoupling module operably coupled to the diplexer unit and operable to isolate a first pair of ports from a second pair of ports, the first pair of ports including a first port and a third port, the second pair of ports including a second port and a fourth port, wherein the first and second ports are coupled to the diplexer unit, the 4-port decoupling module including: a first inductor-capacitor network coupled to the first, third, and fourth ports; anda second inductor-capacitor network coupled to the second, third, and fourth ports; a first frequency band antenna assembly operably coupled to the diplexer unit and operable to transceive wireless signals in the first frequency band; and a second frequency band antenna assembly operably coupled to the third and fourth ports and operable to transceive wireless signals in the second frequency band.
