Miniaturized reconfigurable CRLH metamaterial leaky-wave antenna using complementary split-ring resonators

PAGE TITLE

Overview

 

PAGE SUMMARY

This technology is a design for a Miniaturized Composite Right/Left-Handed (CRLH) Leaky-Wave Antenna (LWA) featuring electronically steerable radiation patterns. The antenna comprises cascaded metamaterial unit cells, each equipped with varactor diodes. By adjusting the voltage across these diodes, the antenna can steer its directional beam from broadside to backward and forward end-fire directions. A key innovation is the use of Complementary Split-Ring Resonators (CSRR) etched underneath each CRLH unit-cell to achieve size reduction without the need for thin interdigital capacitors, addressing PCB manufacturing constraints. This miniaturized antenna is suitable for applications in wireless access points and mobile devices.
