| Popis: | International audience; In this letter, a reconfigurable unit-cell for transmitarray antenna working at X-band is presented. It is designed to provide 1-bit phase quantization using p-i-n diodes. The unit-cell is based on multi-layer frequency selective surfaces with the use of two substrates and a combination of a C-patch and a ring slot loaded by a rectangular gap. It is optimized using full-wave electromagnetic simulation and verified by using waveguide simulator. The experimental results show that the unit-cell provides two values of transmission phase with a step of 180° at 11.5 GHz. Furthermore, the unit-cell has a low thickness of 0.19 lambda 0 , and is low-cost and easy to fabricate. |
