Title: An ultra-wideband transmit/receive module using 10 to 35 GHz six-channel microstrip multiplexers and its applications to phased-array antenna transceiver systems
Author: Hong, Seung Pyo
Abstract: 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 .
