Abstract
The first microwave phased array antenna steered by optical delay lines is presented. Delay times specified by the antenna steering angle were implemented by switching bias currents of high speed lasers pigtailed to the fibre optic delay lines. No beam squint was observed in the radiation pattern of the antenna as its frequency was switched from the L- to the X-band.
