Tri-band Dual-polarized Multilayer SAR Microstrip Antenna
A novel tri-frequency(C,X and Ku)bands with dual-linear polarized each,multilayer microstrip antenna single element is proposed and presented.The triple band operation is obtained by using two antenna elements,one for a dual-band resonance at C and X bands with dual linear polarization and above is for the Ku band(also with dual linear polarized behavior).The feeding mechanism for the dual antenna element is an aperture coupling through cross shaped slot with different shaped feeding ports(to enhance isolation).The Ku band antenna element has an electromagnetically coupled microstrip T-junction feed for one polarization and a direct feeding for the orthogonal polarization.The multilayer microstrip element exhibits a selective frequency band of operation,good isolation among the different feeding ports,good directivity pattern and high gain for both polarizations at all frequency bands.The performance of the proposed antenna was simulated using a commercial software based on the Finite Element Method(FEM)algorithm.The proposed antenna is designed to meet the requirements of Synthetic Aperture Radar(SAR),where multiple frequency with dual linear polarization is needed.
