Antenna Placement Designs for Distributed Antenna Systems with Multiple-Antenna Ports [PDF]

2012 IEEE Vehicular Technology Conference (VTC Fall), 2012
In this paper, we optimize antenna locations for a distributed antenna system (DAS) with distributed antenna (DA) ports equipped with multiple antennas under per-DA port power constraint. Maximum ratio transmission and scaled zero-forcing beamforming are employed for single-user and multi-user DAS, respectively.

Wideband planar dipole based on dual-layer artificial magnetic conductor

The Journal of Engineering, 2019
A wideband planar dipole based on dual-layer artificial magnetic conductor (AMC) is designed. First, the size of dual-layer AMC is reduced by more than half, and the in-phase band is wider than the single-layer AMC.
