Shared-Aperture Ku/Ka Bands Microstrip Array Feeds for Parabolic Cylindrical Reflector
Sbared-aperture Ku/Ka bands microstrip array feeds of parabolic cylindrical reflector antenna have been developed. Dual-polarized microstrip crossed slots, fed by inverted microstrip lines, are used as Ku-band antennas. Single-polarized square microstrip patches, fed by microstrip lines, are used as Ka-band antennas. The Ka-band microstrip patches are in the upper layer and interlaced with the Ku-band microstrip slots. By sharing the same antenna aperture, the problem of placing two feeds at a focus has been solved. The measured results of 8 Ku-band and 16 Ka-band linear arrays are presented and discussed in detail. The array is modular in form and can be easily scaled to larger aperture.
