In this paper, a lower band negative index metamaterial is developed for specific absorption rate reduction. The proposed metamaterial is printed on the plastic cover body of the wireless device. The metamaterial structure has been designed and characterized using FIT technique based EM simulator CST Microwave studio. The perceptible outcome of this paper is specific absorption reduction using plastic...
In this paper, a paper based negative indexed metamaterial is proposed for electromagnetic absorption reduction of portable wireless devices. The metamaterial structure has been designed and characterized using FIT technique based EM simulator CST Microwave studio. The main outcomes of the paper are EM absorption reduction by 14.23% and 15.3% at 0.9 GHz and 1.80 GHz, respectively using metamaterial...
In this paper, a dual band planar inverted-F antenna (PIFA) is proposed for cellular phone applications. The antenna consists of E-shaped patch, shorting wall, feed point and ground plane. A 1.6 mm thicken FR-4 substrate is used in ground plane to reflect the effect of the circuit board. The finite integration technique (FIT) based computer simulation technology (CST) microwave studio is used in major...
A multiband compact printed monopole antenna is proposed for mobile phone. In this configuration, the antenna comprises a slotted rectangular‐shaped radiator, microstrip‐fed line, and a slotted ground plane on FR‐4 substrate. The total antenna dimensions with ground plane are 78 × 40 × 0.8 mm3. The measured results show that the proposed antenna has an impedance bandwidth 358.4 MHz (0.60–0.95 GHz,...
This paper presents a new multiband antenna is proposed for Wireless communication. Commercially available software High Frequency Structural Simulator (HFSS) and Computer Simulation Technology (CST) microwave studio was adopted in this investigation. The presented antenna consists of a slotted rectangular patch with a rectangular ground plane. The antenna exhibits four resonates at 2.05 GHz, 2.45GHz,...
