Metamaterial-Backed Conformal Antennas for Space Exploration

Completed Technology Project

Project Introduction

The purpose of this experiment is to demonstrate a successful X-band antenna array fabricated on a high-permittivity substrate together with bandgap metamaterials that enhance the antenna performance by reducing surface waves.  The current goal is to demonstrate X-band patch antenna and bandgap metamaterials separately, then demonstrate antenna patches and metamaterial integrated into a working array. 


The high-permittivity substrate (er = 10.2) allows individual antenna patches to be made smaller and also mimics substrates (Si, SiC, GaAs, InP, GaN) used in MMIC and OEIC technology. If successful, the antennas may be integrated together with receiver components on the same substrate for miniaturization. Another important benefit is that surface waves are inhibited so that devices on the same substrate are isolated from each other.
