Transmitter-receiver

摘要

A transmitter 18 and a receiver 24 are formed integrally with a dielectric substrate 12. The transmitter 18 includes a transmitter filter 14 and a transmitter antenna 16 connected to the transmitter filter 14. The receiver 24 includes a receiver filter 20 and a receiver antenna 22 connected to the receiver filter 20. The transmitter filter 14 is formed with resonant elements 30a-30c arranged parallel to each other. The transmitter antenna 16 includes an antenna 32 formed from an electrode film on the upper surface of the receiver filter 20. The receiver filter 20 is formed from resonant elements 34a-34c arranged parallel to each other. The receiver antenna 22 includes an antenna 36 formed from an electrode film on the upper surface of the dielectric substrate 12.
