摘要：

We propose a new circularly polarized elliptical microstrip antenna intended for use in circularly polarized synthetic aperture radar (CP-SAR) systems operated in L-Band (1 27 GHz) The design and fabrication process aim to fulfill the challenging specification for our CP-SAR onboard unmanned aerial vehicle (UAV) We apply the proximity-coupled single feeding method by a microstrip line positioned 45 counterclockwise to the semi-major axis of the ellipse to generate the left-handed circularly polarized wave radiating from the patch Both simulated and measured results are presented For a single-element model the simulation gives an axial ratio bandwidth ( < 3 dB) of about 0 85% (10 8 MHz) which is consistent with the bandwidth measured for the measured fabricated model of 082% (10 4 MHz) and 091% (11 6 MHz) simulated for an antenna array model These results satisfy the specification for our CP-SAR sensor onboard UAV (C) 2010 Elsevier GmbH All rights reserved
