A Method for Tailoring the Gain Pattern of a Single Antenna Element
In this paper, we present a novel method to tailor the radiation pattern of an antenna element, such as a single element of an array, by maximizing its partial radiation efficiency in the desired angular space.

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

The eleven antenna: a compact low-profile decade bandwidth dual polarized feed for reflector antennas [PDF]
A novel dual polarized ultrawide-band (UWB) feed with a decade bandwidth is presented for use in both single and dual reflector antennas. The feed has nearly constant beam width and 11 dBi directivity over at least a decade bandwidth.
