Design of Metamaterial Antenna For Wireless Applications
Journal Title: GRD Journal for Engineering - Year 2016, Vol 1, Issue 0
Abstract
A multiband compact planar antenna was designed with frequency notched function, the antenna with CPW fed is consist of various microstrip resonators, such as closed ring resonator and SRR, producing some discontinuous resonant bands is suggested. Metamaterial is artificial material that may exhibit electromagnetic (EM) responses not readily found in natural. Presently, it has gained considerable attention since its unique EM characteristics can be advantageous in design of novel EM components and devices. It may be used for making perfect lens or even invisibility cloaks. other examples are that electromagnetic band gap/photonic band gap (EBG/PBG) and artificial magnetic metamaterial have already been used in antennas design, which might be used to open the door to obtain the compact and high performance EM components and devices. Using Agilent Technologies ADS Software, the antenna is designed and simulated for 2.1/3.5/5GHZ UMTS/worldwide interoperability for microwave access (WiMAX)/Wireless LAN (WLAN) application with return loss of more than -10dB. To achieve a very wide bandwidth the rectangular ground planes and the split-ring loops dimensions are tuned. to improve the return loss performance in the required band a tapered transmission line is adopted. Measurement results shows that the proposed UWB antennas have a wide bandwidth from 3.1 to 10.6 GHz. To achieve a very wide bandwidth the rectangular ground planes and the split-ring loops dimensions are tuned.
