Design of Compact Annular Ring Antenna on Metamaterials for Improved Radiation Pattern and Gain
نویسندگان
چکیده
Simulated and experimental investigations have been carried out on annular ring antenna designed on metamaterial substrate. Different configurations of Sshaped metal structure are designed on RT-Duroid substrate to achieve metamaterial behavior at the frequency of 10.5 GHz. Annular ring antenna is designed for TM31 mode on the metamaterial configurations. The antenna provides a huge size reduction of 87.58% when designed on metamaterial. The gain is improved from 1.0 dB for a simple ring to 6.22 dB on the ring antenna on metamaterial. Improvement is also clearly visible in the radiation pattern.

Complementary Split Ring Resonator Effects on Radiation Pattern Reconfigurable Circular Microstrip Antennas
In this study, a radiation pattern reconfigurable microstrip antenna is designed and fabricated. The antenna’s radiation pattern is directed in 9 different angles by employing a radiating patch and embedding complementary split ring resonators (CSRR) on the ground plane. The radiating patch is of circular shape, while for CSRR elements both circular and rectangular shapes are investigated. The ...

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...

In this article, we present a new design of a coplanar waveguide fed (CPW-fed) ultra-wideband (UWB) antenna with dual band-notched characteristics. Two notched frequency bands are achieved by using two inverted U-shaped stepped impedance resonators. The proposed antenna can operate from 2.82 to 11 GHz (118%), defined by VSWR< 2, except two notched bands around 3.5 GHz (WiMAX) and 5.5 GHz (WLAN)...
