Equilateral Triangular Microstrip Antenna for Circularly-Polarized Synthetic Aperture Radar
By
Progress In Electromagnetics Research C, Vol. 8, 107-120, 2009
Abstract
An equilateral triangular microstrip antenna is proposed for circularly-polarized synthetic aperture radar (CP-SAR) systems operated in L-Band (1.27 GHz). For airborne application, a prototype antenna patch is designed, fabricated and tested. Electromagneticallycoupled, dual-feeding method is applied to generate the circularly-polarized wave radiating from the patch. The fabricated patch exhibits an axial ratio bandwidth (< 3 dB) of about 0.58% (7.4 MHz), which is consistent with the value of 0.57% (7.24 MHz) from the simulation.
