Multi-beam modulated metasurface antenna for 5G backhaul applications at K-band

Comptes Rendus. Physique, 2021
We explore the use of a new modulated metasurface (MTS) antenna topology as solution for wireless backhaul at K band. The proposed structure is composed of a quasi-optical beamformer, which feeds the modulated MTS radiating aperture.

Bandwidth enhancement for QMSIW antenna by using dual cavity and triangle slot [PDF]

International Journal of Electronics and Telecommunications
The miniaturization of substrate-integrated waveguide (SIW) antenna suffers from the narrow impedance bandwidth. It occurs on the quarter mode substrate integrated waveguide (QMSIW) antenna that has 75% miniaturization of the full mode SIW. This research

Optimum number of antenna elements in a sub-array for highest G/T

, 1998
There are a number of different parallel arm feed topologies which give the same radiation pattern characteristics. On the of her hand, noise temperature and efficiency of those feed structures will possibly, be not the same.
