Abstract :
A microstrip antenna is described that produces good circular polarisation out to wide-scan angles without adjustments to the ground plane. A two-layer dielectric structure is used to realise the optimum dielectric constant and to permit the centre frequency of the antenna to be adjusted over a small frequency range of approximately double the antenna bandwidth.
