A Ku-band cylindrical conformal waveguide slot array antenna is presented. The phase differences between slots on the cylindrical surface are compensated by adjusting the position of radiation slots. As a result of adjusting the position of radiate-slot, the periodicity of high side-lobe is analyzed.
The design of a tri-band dual-polarization (TBDP) shared-aperture microstrip array antenna for synthetic aperture radar (SAR) applications is presented. It operates at L-, S- and X-bands with a frequency ratio of 1:2.8:8. This TBDP shared-aperture array is assembled by two L/S and L/X DBDP shared-aperture sub-arrays with one L-band dual-polarized sub-array. A prototype array has been fabricated and...
