Radiation pattern measurements of an integrated transverse electromagnetic horn antenna using a terahertz photomixing setup
Résumé
We report experimental radiation pattern measurements of a transverse electromagnetic horn antenna at the millimetric/sub-millimetric frontier (280–350 GHz). The antenna is fed by a monolithically integrated uni-travelling-carrier photodiode illuminated by an optical beatnote (photomixing) at 1.55 μm . The detection is performed using an electronic sub-harmonic mixer and the whole characterization system is working at room temperature. Radiation patterns are measured in the E -plane and compared with electromagnetic simulations with a good agreement.
