The Invention
UW researchers have a new ultra-wideband, electronically reconfigurable reflectarray antenna design with 1-bit phase quantization. One of the innovative features of this design is that it achieves electronic reconfigurability using only a single PIN diode switch and has a simplified implementation mechanism. The proposed reflecting unit-cell consists of an antenna placed on top of a ground plane and a reflecting-mode phase shifting circuitry employing a single PIN diode switch positioned below the ground plane. The unit cell has an antenna and a reflecting circuit using open-ended transmission lines. When the unit cell is illuminated with an incident electromagnetic wave, the wave is entirely reflected with a phase shift that can be adjusted electronically (between 0°/180°) by controlling the PIN diode switch. This structure can provide a 0°/180° phase shift with a maximum error of ±20o with a bandwidth exceeding 82% (3.45-8.25 GHz).
