摘要：
This paper presents the design and realization of a dual frequency antenna array for application in Synthetic Aperture Radar. The array consists of 64 C-band elements interleaved with 4 L-band elements incorporated with feeding network in one integrated, multilayer, LTCC compatible structure. The Antenna has been designed to operate with dual-linear polarization in both frequency bands. The achieved bandwidths are 100 MHz in L-band and 400 MHz in C-band. Several techniques for suppressing orthogonal polarization has been implemented to achieve very low cross-polarization coefficient in both frequency bands. The beam forming network has been designed to provide modified cosec2 radiation pattern suitable for radar applications.
