An ultra-wideband transmit/receive module using 10 to 35 GHz six-channel microstrip multiplexers and its applications to phased-array antenna transceiver systems

This dissertation introduces new and simple techniques for suppression of multispurious
passbands, which are inherent to the conventional microstrip parallel coupleline
bandpass filters. In addition, the operation of harmonic suppression is analyzed
using a simple model.
Special emphasis is placed on the applications of several new filter designs for
microstrip diplexers and multiplexers. Compact, full-duplex beam scanning antenna
transceiver systems with extremely broad bandwidth have also been developed.
Recent advances in broadband monolithic microwave integrated circuit (MMIC)
amplifiers make the realization of extremely broadband phased-array transceiver systems
possible. The ultra-wideband phased-array transceiver systems can be used in multi-band
mobile satellite communication systems and wideband radars. This dissertation presents
a multi-band, compact, full-duplex, beam scanning antenna transceiver system for
satellite communications and two designs of ultra-wideband, low-cost radar systems as
applications of the MMIC amplifiers. In addition, a multi-frequency antenna has been developed. A single-feed triple
frequency microstrip patch antenna is presented as an answer to the recent demand for
multi-function systems in the wireless communications.
In summary, the research presented in this dissertation covers every component
required to build an ultra-wideband, full-duplex beam scanning phased-array antenna
transceiver. The work done in this dissertation should have many applications in the
wireless communication systems and wideband radar technologies.
