A METAMATERIAL-BASED E-PLANE HORN ANTENNA

Groove Gap Waveguide (GGW) H-plane Horn ‎Antenna and a Method for Its Back lobe ‎Suppression

recently a new structure called groove gap waveguide (GGW) is ‎introduced to implement low loss microwave component devices ‎especially for millimeter wave applications. This paper presents a ‎new type of H-plane horn antenna making use of this new technology ‎in which backward radiation is significantly suppressed by ‎introducing a high impedance surface at the antenna aperture. The ‎high impe...

Metamaterial Based Multiple Frequency Antenna

Antennas that are electrically small, efficient and have significant bandwidth would fill many needs of new generation communications systems if antenna engineers could reconcile these usually contradictory requirements. The introduction of the so-called metamaterials (MTMs), artificial materials which have engineered electromagnetic responses that are not readily available in nature, has provi...

Development of an Enhanced Gain Substrate Integrated Waveguide H-plane Horn Antenna Using Thin Substarte

In this paper a dual band and high gain H-plane horn antenna implemented by substrate integrated waveguide (SIW) using a single layer thin substrate is introduced. The proposed antenna consists of five parts of rectangular waveguide with different width arranged in a staircase manner to allow mode combination of fundamental and higher propagating modes of the structure. By adjusting the length ...

Analysis of Metamaterial Based Microstrip Array Antenna

A Metamaterial-Based Handset Antenna with the SAR Reduction

A method to reduce the specific absorption rate(SAR) of the antenna for WiMAX mobile communication is proposed in this paper. The SAR reduction is achieved by miniaturizing the physical size of the antenna for the given resonance frequency by devising a metamaterial-composite rightand left-handed(CRLH) configuration-based radiator much smaller than the quarter-guided wavelength adopted a lot in...
