Abstract :
Holographic metamaterial antennas are a promising technology to increase consumer usage of satellite capacity by providing an economical means of connectivity on mobile platforms. Metamaterial antennas are built for portability - thin, lightweight, low-power consuming, and having no moving parts - achieving precision beam-steering electronically. We develop an optimization algorithm capable of performing adaptive optimization of antenna patterns. The efficacy of the algorithm is demonstrated experimentally.
