A Thinned Array Solution for an ISOFLUX Antenna from Geostationary Satellite
A Thinned array configuration has been successfully designed and demonstrated implementing an ISOFLUX pattern profile from on-board geostationary platform. A Fourier synthesis procedure was efficiently utilized to obtain the element excitations. Array thinning performed by excluding elements receiving less than −12.5dB of the input signal, thus reducing total feeder loss. Sequential rotation across array quadrant used to suppress the cross-polarization by almost 40dB. Close agreement of measured results validate the proposed design and synthesis technique.
