Series CRLH feed network for antenna array

What is it about?

Novel way to design a compact series feed network which provides flexible power output distribution and phase offset.

Why is it important?

The desired phase response of the proposed series CRLH feed network is realized in a compact and low-cost design,which offers a backward-to-forward beam scanning capability for the phased array antenna. Furthermore, current amplitude distributions of the series CRLH feed network can be arbitrarily allocated by modifying the coupling factors. In this paper, two prototypes with uniform and binomial current amplitude distributions were designed then fabricated to validate the proposed features and performances. Incorporating with the feed networks, the proposed dual-polarized phase array antenna demonstrates the expected backward-to-forward beam scanning and wide range beam shaping capability for both (two orthogonal) polarization states. In summary, the proposed feed network may serve as a favorable candidate for phased array antenna with beam scanning and shaping requirements such as for polarimetric radar system and image processing applications that demands enhanced spatial information.
