A Study of Using Metamaterials as Antenna Substrate to Enhance Gain
Using a commercial software, simulations are done on the radiation of a dipole antenna embedded in metamaterial substrates. Metamaterials under consideration are composed of a periodic collection of rods, or of both rods and rings. The S-parameters of these metamaterials in a waveguide are analyzed and compared with their equivalent plasma or resonant structure. Farfield radiation is optimized ...
متن کاملMicrostrip 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 کاملDevelopment 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 ...
متن کاملA meta-substrate to enhance the bandwidth of metamaterials
We propose the concept of a meta-substrate to broaden the bandwidth of left-handed metamaterials. The meta-substrate, which behaves like an inhomogeneous magnetic substrate, is composed of another kind of magnetic metamaterials like metallic closed rings. When conventional metamaterial rings are printed on this kind of meta-substrate in a proper way, the interaction of the metamaterials units c...
متن کاملA Study of Metamaterial Based Electrically Small Antenna to Enhance Gain
This is a review paper in which electrically small metamaterial-based antennas are discussed from the industrial point of view using mobile phones as the application example and dual band microstrip antenna with metamaterial structure for dual band operation. The most interesting feature of the design is the ability of enhancing the gain and total efficiency of the antenna without affecting the...
