A Compact Microstrip Diplexer Using Composite Right-/Left-Handed Transmission Line with Enhanced Harmonic Suppression

In this article, a novel microstrip diplexer operating at 1.8 GHz (GSM band) and 2.2 GHz, based on composite right-/left-handed transmission line (CRLH TL), is presented. The CRLH TL, using only one cell, is initially proposed based on Koch-shaped ex...
The diplexer, commonly used to make receiving and transmitting share a common antenna, is an essential three-port device and typically consists of several bandpass (BPF) and bandstop (BSF) filters. Consequently, the performance of the BPF determines the comprehensive performance of the diplexer to a great extent. However, with recent...
