Mode-Reconfigurable Bandpass Filters with Liquid Metal Enablement
(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 ...
Highly Miniaturized VHF Helical Filters with Fully Reconfigurable Capabilities
(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 Low-Power Antenna Reconfiguration Through Biasing of Magnetic Loads
(2017-05-12)
In modern RF systems, tunable devices are increasingly necessary to provide agility in crowded spectral environments. The antenna, as an integral part of any wireless system, must be capable of operating well at multiple ...
Limitations and evaluation of the linear assumption on antenna design
(2022-05-13)
A common assumption made by antenna engineers is to consider a system to be linear and time-invariant (LTI). This assumption is incredibly powerful and has enabled a century of advancements, but consequently has perhaps ...
