Broadband Low RCS and High Gain Microstrip Antenna Based on Concentric Ring-type Metasurface

This paper presents design a High Gain Small Size Microstrip Patch Antenna for X-Band applications such as Moving target RADAR sensor, Motion detector, Microwave camera, Ground Penetration RADAR sensors, wall penetration scanners and many medical applications. Now we have to selected circular geometry of micro strip patch antenna because circular geometry overcomes edge effect of antenna. The proposed antenna is designed to operate for X-band at the centre frequency of 10 GHz. The proposed Circular patch antenna is compact and easy to body mount with a high efficiency. The compactness makes it a better choice as compare with other antenna in the X-band. The proposed antenna shows a very sharp return loss of -46 dB at 10 GHz having narrow pattern with a good gain of 4.7 dBi. This enables its use in high directional applications. The paper represents the designing steps, and the simulation result obtained. The software used here for this circular shaped microstrip antenna is IE3D. Various parameters such as gain, power, radiation pattern, and S11 of the antenna are mentioned.

Wireless Applications

Antennas play a vital role in wireless communication; a thirst of excellence in this area is unending. Proposed work describes a concept of fractal multiband antenna designed in the hexagon shape. Basically fractal is the concept used in Microstrip antenna for giving better results than conventional Microstrip antenna. By using hexagonal fractal antenna we can possibly achieve the radiation pattern with high gain. The coaxial feeding is used and multiple hexagons are interconnected in array for maintaining conductivity and to preserve electrical self similarity. Hexagonal antenna is used for different wireless applications. The proposed antenna frequency band covers a large number of wireless communication applications including GPS (1.6GHz), Bluetooth (2.4 GHz) & WLAN (3.6GHz). Antenna design has been designed and simulated by using the software Ansoft’s HFSS and parameters like bandwidth return loss, directivity, VSWR are analyzed. Fabrication of the antenna is done by using wet-etching method, on FR-4 dielectric substrate material. Experimental results are taken on Vector Network Analyzer (VNA) and those obtained results were compared with simulated results. The hexagonal fractal antenna array is found to possess predictable multiband characteristics.
