Microstrip antenna diplexers for wireless communications

In this paper we present a dual-band antenna integrated with diplexer. Compact microstrip diplexer was designed using pseudo-interdigital stepped impedance bandpass filters with improved stopband. Microstrip patch antenna designed to support dual-band operation at 2.5-2.6 GHz and 5.1-5.5 GHz frequen...

Description
Summary:In this paper we present a dual-band antenna integrated with diplexer. Compact microstrip diplexer was designed using pseudo-interdigital stepped impedance bandpass filters with improved stopband. Microstrip patch antenna designed to support dual-band operation at 2.5-2.6 GHz and 5.1-5.5 GHz frequency bands was integrated with diplexer. As a result of integration 20 dB separation of the channels has been achieved. The proposed system can be used in novel architectures for WiMAX RF Front-End.
