Abstract

The transmission and receiving of several channels via a single antenna is a long standing problem. We have developed a multi-channel coupler in the VHF frequency range enabling to reduce the number of antennas to one third of channels number used at one time. The system is based on a meander stripline used for each coupling channel. The channels were matched simultaneously to a single antenna using a controlled capacitor banks located on each channel. The multi coupler performance shows low insertion loss and low return loss for each channel attached to the antenna.
