We demonstrate that an integrated lens antenna (ILA) with a double lens (DL) focusing
system can provide simultaneously a high broadside directivity and a low scan loss over a …

A wideband 5G millimeter-wave multiple-input multiple-output (MIMO) magnetoelectric (ME)
dipole antenna integrated with partially reflective surfaces (PRSs) is proposed. Each ME …

In this paper, a method of enhancing gain in a microstrip patch array antenna using two
metallic plates for 24 GHz radar applications is presented. A 4× 1 linear microstrip square …

Integrated lens antennas are widely used in high gain and beam steering applications at
millimeter-wave frequencies. The ILA has often large height and suffers from significant scan …
