发明名称 COMPOSITE ANTENNA FOR DUPLEXER-FREE DUPLEX OPERATION TERMINALS AND METHOD
摘要 An antenna assembly includes a receiving antenna and a separate transmitting antenna with an isolation circuit disposed in between to thereby isolate the Tx and Rx signals and provide a sufficient amount of attenuation outside the desired frequency band. The dual antenna structure enables the elimination of a conventional duplexer for duplex operation. In this context, the arrangement minimizes occupied space on the PCB while reducing manufacturing costs.
