A tunable microwave slot antenna based on graphene

Microwave signals can then interact with these conductive regions and with correct design, tunable antennas and circuits can be created. 4.2GHz – 6 GHz optically tunable cavity backed slot antenna. Silicon samples can be seen in the slot and an optical fibre is being held in place over one sample for tuning.

On top of the slot there is an air cavity and on top, a small portion of a hemispherical lens. The fractional bandwidth of such antennas is around 10 percent, which is good enough for heterodyne imaging applications.The new geometry makes … Best Paper Finalists — Eucap 2016 Lars Foged; Francesco Saccardi (Microwave Vision Italy); Andrea Giacomini (Microwave Vision Italy (MVI)); IMS2019 Technical Sessions | IMS2019 A novel method using dual-mode cavities to create transmission zeros, a folded ridge waveguide dual-band tunable bandstop filter, and a filter using a resonant inverter structure will also be presented.
