Parametric study on effect of solar-cell position on the performance of transparent DRA transmitarray

Linearly polarized transparent dielectric resonator antenna (TDRA) transmitarray is designed and investigated for 12 GHz applications. A parametric study on the effect of solar-cell position on the radiation characteristics of the TDRA transmitarray. The unit cell consists of two TDRAs arranged back-to-back with one on either side of a perfect transparent conducting ground plane. The waveguide model is used to calculate the required compensation phase of each cell in the transmitarray. The radiation characteristics of a 9 × 9 linearly polarized transparent transmitarray antenna are investigated in different positions of solar-cell with respect to the DRA. The peak gain is 20.22 dB with a 1-dB gain bandwidth is more than 2 GHz (16.67%) for the TDRA transmitarray without solar-cell. The solar-cell is integrated with TDRA transmitarray with different positions for small satellite applications. The radiation characteristics of the transmitarray are simulated and calculated using the finite integral technique (FIT).
