soft-surface structure, the radiation performance is significantly improved, including
enhanced radiation field in the maximum radiation direction, lower cross polarization
of the H-plane, and reduced sidelobe radiation.
Mechanism for Performance Enhancement of Antenna Array by the
Soft-surface Structure
In order to investigate the mechanism for the novel soft-surface structures placed in
the antenna array, the electric field distributions on the top surface of the substrate
for the middle two-row eight elements of the antenna array simulated by HFSS are
shown in Fig.
