Beam and polarization reconfigurable microstrip antenna based on parasitics
Allayioti, M; Kelly, JR; Mittra, R (Wiley, 2018)This paper presents a dual‐notch polarization and beam reconfigurable microstrip antenna. It uses parasitics which incorporate switches to steer its beam away from boresight and dual notches which, again, incorporate ... -
Gallium-Based Liquid Metal Substrate Integrated Waveguide Switches
Alkaraki, S; Kelly, J; Borja, AL; Mittra, R; Wang, Y (IEEE, 2020-12-01)IEEE This letter presents a new approach for reconfiguring substrate integrated waveguide (SIW) devices. It involves allowing or prohibiting the wave propagation by using a removable wall which is built from a series of ... -
Hybrid Parasitic Linear Array Antenna for Fine Beamsteering Applications
Uchendu, IE; Kelly, JR; Mittra, R; Gao, Y (Institute of Electrical and Electronics Engineers (IEEE), 2021-06)This paper presents an antenna that utilizes two beam steering techniques in concert in order to improve the antenna gain and steering resolution. Phased array steering is employed to achieve coarse resolution beam steering ... -

Reconfigurable Liquid Metal Based SIW Phase Shifter
Alkaraki, S; Borja, A; Kelly, J; Mittra, R; Gao, Y (Institute of Electrical and Electronics Engineers, 2021)Abstract—This paper presents the first substrate integrated waveguide (SIW) phase shifter that can be reconfigured using liquid metal. This digital phase shifter exhibits low insertion loss and is reciprocal and bidirectional. ...
