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 TelecommunicationsThe 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
