“…However the introduction of stacked configuration with printed elements poses fabrication challenges and requires accurate alignment of the layers. Narrow bandwidth behavior have also been addressed by the introduction of single layer dual resonance elements such as parallel dipoles, spit rings and combination of different slot configurations [7][8][9][10][11][12]. However dual resonance elements with resonances in different bands require complex phasing techniques along with dual feeding mechanism that increase the complexity of the array design.…”

Significant improvements in terms of bandwidth of reflectarray antennas have been achieved by introduction of innovative paper substrate dielectric materials. Three differently custom composed organic dielectric substrates have been characterized for dielectric properties using a broadband technique based on open ended coax cable method. The substrates show low dielectric permittivities of 1.81, 1.63 and 1.84 along with a loss tangent of 0.053, 0.047 and 0.057. Validation of using the proposed substrates for reflectarray antenna was done by modelling and fabricating reflectarray unit elements on the three substrates. Scattering parameter analysis of unit reflectarray elements show encouraging results with a broadband frequency response of 340 MHz at a phase gradient of 0.14º/MHz. Thus the proposed substrate could serve exceptionally to address the narrow bandwidth problem in reflectarray antennas.
