Microstrip Antenna Gain Enhancement using Near Zero Refractive Index Metamaterials
Some useful features of microstrip patch antennas are low profile, low weight and easy fabrication. However this type of antenna suffers from having a low gain, caused by propagation surface waves. In this paper, a new near zero refractive index metamaterial (MTM) unit cell is designed and fabricated as a superstrate over a Rectangular Microstrip Patch Antennas (RMPA). In order to obtain a maxi...
متن کاملDual-band double-negative-index fishnet metamaterial at millimeter-waves.
An effective negative refractive index (NRI) is demonstrated and experimentally verified for the first two propagation bands of a fishnet-like metamaterial at millimeter-wave frequencies. The dual-band NRI behavior is achieved by engineering the diffraction order (±1, ±1) associated with the internal mode supported between holey layers to correspond with the second propagation band. In addition...
متن کاملNear - zero refractive index photonics
The control and manipulation of light on the nanoscale — the primary aim of nanophotonics — is of fundamental scientific interest and plays a key role in telecommunication technologies and energy management. Yet, because light–matter interactions are usually weak and hard to confine, they often need to be assisted by the use of suitably designed macroscopic media. For instance, the use of caref...

متن کاملA Near-Zero Refractive Index Meta-Surface Structure for Antenna Performance Improvement
A new meta-surface structure (MSS) with a near-zero refractive index (NZRI) is proposed to enhance the performance of a square loop antenna array. The main challenge to improve the antenna performance is increment of the overall antenna volume that is mitigated by assimilating the planar NZRI MSS at the back of the antenna structure. The proposed NZRI MSS-loaded CPW-fed (Co-Planar Waveguide) fo...
