Frequency-Agile Microwave Filters For Radars With Simultaneous Transmission and Reception
Saeedi, Shahrokh (2015-12)Multi-band/multi-mode wireless communication systems have been receiving increased attention recently due to their potential for spectrum management in a dynamic spectral environment. Similarly radar systems, which can ... -
Highly Miniaturized VHF Helical Filters with Fully Reconfigurable Capabilities
Arroyo Diaz, Eivy (2019-05-10)The demand for frequency reconfigurable bandpass and bandstop filters within the VHF-UHF frequencies continues to rise due to the increasingly crowded radio frequency (RF) spectrum. As a result, higher levels of isolation ... -
Investigation of Designs for Tuning of Mutual Coupling and Operating Frequency in High-Power Slot Antenna Arrays
Schaeffer, Andrew (2020-05-08)Today's congested frequency spectrum calls for frequency agile arrays and antennas that can avoid the interference of the myriad of RF sources, from satellites to amateur radio, that take up the same bandwidths. Previous ... -
Microwave filters for next generation radio frequency transceivers
Ariturk, Gokhan (2023-08-04)Increased data rates in wireless communications enforce unprecedented performance metrics on the front-end filters to operate in crowded spectral bands. These requirements include strong selectivity, low insertion loss, ... -
Mode-Reconfigurable Bandpass Filters with Liquid Metal Enablement
McClung, Sarah N. (2017-08)The RF spectrum grows increasingly crowded every year due to technological advancement and more accessibility to wireless devices. Overcrowding leads to the desire for frequency agile microwave systems with dynamic spectrum ... -
Theory, Design, and Fabrication of Frequency Agile Filtennas
Thibodeau, Marc (2020-07-30)With the development of modern wireless systems, the spectral environment has become increasingly crowded. This has spawned a strong interest in frequency, bandwidth, and pattern reconfigurable RF front ends, which can ...
