|Title:||Multifrequency and Multipolarization Antennas|
|Abstract||The goal of this project is to develop the theoretical tools and to acquire the knowledge needed to design and build multifrequency, polarimetric antenna systems, with bandwidth and radiation properties suitable for use in high resolution radar systems - especially airborne SAR systems.
The installation of the relatively large SAR antennas on an aircraft represents a technical challenge and a major cost factor. The availability of compact, leightweight multifrequency antennas will have significant impact on airborne, multifrequency SAR utilization, as installation will be cheaper when fewer antennas are needed.
The work has focussed on designing elements of a combined L- and C-band antenna using stacked microstrip patches as radiating elements. It has proven difficult to achieve the desired bandwidths (100 MHz at L-band, more at C-band) at both frequencies simultaneously, and a trade-off will be needed.|
