Abstract :
A stubloaded reflectarray antenna, which combines the features of conventional parabolic reflector and planar microstrip patch array, is presented. Equiphase distribution at the aperture of the reflectarray is realized by adding stubs of appropriate lengths at each element. A reflectarray of 10×10 elements designed at 10 GHz exhibiting a gain of 22.5 dB and first side lobe level of -12.4 dB is presented. MATLAB program has been used in the design of stub loaded reflectarray.
