Abstract:
A dual circularly polarised Contrawound Quadrifilar
Helix Antenna (CQHA) is proposed for land mobile satellite
MIMO systems. The CQHA is combination of two QHAs with
opposite winding rotation where one is positioned inside of the
other. Low return loss and isolation of the CQHA elements is
achieved by varying the radius of the outer QHA while the inner
QHA is fixed. Preliminary evaluation of its MIMO capability is
done by calculating the mean effective gain and analysing the
polarisation correlation of each QHA. A deployment
configuration of two CQHAs for land mobile satellite /DVB-SH
vehicular rooftop antenna is also proposed in this paper. Mean
effective gain of the CQHA configuration for a complete azimuth
plane is calculated by considering Gaussian Angle of Arrival
model for the angular distribution of the incident waves.
