Abstract :
A novel design of a printed single layer reflectarray antenna based on grounded metallic loop-wire Miniaturized-Element Frequency Selective Surface (MEFSS) is presented. The proposed sub-wavelength MEFSS unit cell with localized frequency response and minimal dependency to the angle of incidence allows for broadband performance of the reflectarray antenna without any optimization algorithm. The proposed reflectarray antenna with total dimension of 260mm×260mm and F/D=1.02 is fabricated to validate the design method. A maximum gain of 26.3 dBi with 3dB-gain bandwidth of 17% and 3-dB beamwidth of 6° is achieved at x-band.
