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 کاملGain Enhancement of the Patch Antenna Using TSRR NRI Superstrate
This article presents a high gain patch antenna with negative refractive index (NRI) superstrate for the application of Radio frequency energy harvesting system. Triangular split ring resonators (TSRR)-strip line are used as a NRI superstrate to enhance the gain of the patch antenna. It is demonstrated that the proposed triangular split ring resonator (TSRR) structure metamaterial yields negati...
متن کاملGain Enhancement of the Vivaldi Antenna with Band Notch Characteristics Using Zero-index Metamaterial
In this letter, a tapered slot ultrawide band (UWB) Vivaldi antenna with enhanced gain having band notch characteristics in the WLAN/WiMAX band is presented. In this framework, a reference tapered slot Vivaldi antenna is first designed for UWB operation that is, 3.1–10.6 GHz using the standard procedure. The band-notch operation at 4.8 GHz is achieved with the help of especially designed comple...
متن کاملEnhanced Gain Planar Inverted-F Antenna with Metamaterial Superstrate for UMTS Applications
Planar inverted-F antennas (PIFA) are widely used in wireless hand-held devices due to their small-size, moderate bandwidth and radiation patterns. However, the radiation patterns of such antennas degrade when placed very close to a conductive finite ground plane. In this paper, an engineered magnetic superstrate is introduced to enhance the gain of PIFA antennas. The engineered magnetic supers...
متن کاملDesign of a Single Negative Metamaterial based Microstrip Patch Antenna
This paper describes the design and simulation of the new Ɛ negative metamaterial unit cell structure and then the unit cells are combined to form 3D array which use as metamaterial cover with a single microstrip patch antenna. The new Ɛ negative metamaterial is based on the ELC resonator structure, which is used for obtaining the negative value of permittivity and positive value of permeabilit...
