Abstract:
This work proposes an electrically small 3D beam-
forming antenna for PHYsical Layer (PHY-layer) security. The
antenna comprises two layers of stacked patch structures, and is
a five-mode five-port MIMO system operating around 1.85 GHz
with electrical size ka = 0.98 and radiation efficiency of up to
55%. By studying the properties of the excited modes, phase
and amplitude control allow for unidirectional beam scanning
towards any direction around the elevation and azimuth planes.
PHY-layer security is investigated using the directional modu-
lation (DM) technique, which transmits unscrambled baseband
constellations symbols to a pre-specified secure direction, while
simultaneously spatially distorting the same constellations in all
other directions. Bit Error Rate (BER) calculations reveal very
low values of 2 × 10−5 for the desired direction of the legitimate
receiver, with BER< 10−2 beamwidths of 55◦ and 58◦ for the
azimuth and elevation planes, respectively.
