In this paper, we have designed and fabricated a novel microstrip diplexer. It has two quite close channels at 1.67 GHz and 1.88 GHz make it suitable for FDD schemes and GSM applications. The proposed structure includes two coupled meandrous open loop resonators which are coupled to spiral cells. An...
