Introduction

Ayman H Dorrah is a notable inventor based in Toronto, Canada. He has made significant contributions to the field of phased array technology, particularly with his innovative approach to beam scanning.

Latest Patents

Ayman holds a patent for his invention titled "Peripherally Excited Phased Arrays." This invention introduces a new type of phased array known as the peripherally-excited phased array (PEX-PA). The PEX-PA consists of an electrically large metallic cavity that is excited by weighted antenna sources located only at its periphery. The top surface of the cavity features a carefully designed configuration of apertures, while the cavity itself is filled with a dielectric material. This technology allows for beam scanning in multiple directions with a significantly reduced number of passive or active phase shifters. Notably, the PEX-PA scales the number of phase shifters based on the circumference of the cavity rather than its area, which is a departure from conventional phased array designs.

Career Highlights

Ayman has dedicated his career to advancing technologies that enhance communication and radar systems. His work has been recognized for its innovative approach and practical applications in various fields.
