Abstract :
This paper presents a new diplexer using one-dimensional (1D) photonic band gap (PBG) structures to switch transmit/receive paths in a multiband transceiver antenna system. The 1D PBG structure consists of periodically etched holes on the ground plane along a microstrip-line. The new diplexer is optimized by parametric analysis, tapering and meandering of PBG bandstop filters, and full-wave simulation. A diplexer operating at four bands of 10, 12, 19, and 21 GHz is demonstrated with measured and simulated results. The new 1D PBG diplexer should be useful in multiband transceiver systems.
