Design Performance of UWB Antenna for Portable Devices Applications

摘要

Objectives: To review on the design of UWB antennas for the wireless applications and to propose suitable design. Methods/ Statistical Analysis: The study introduces a novel structure methods implementing the design are cutting multiple T-slots on a rectangular patch. The proposed structure occupied an area of 875 mm2 produces a reflection coefficient is ?44.58 dB and maintained S11 ≤ ?10 dB in the entire operating UWB region. The multiple T-slot antennas IBW’s are 4.0?3.0 GHz (1000 MHz), 5.0?6.0 GHz (1000 MHz), 9.0?11.0 GHz (2000 MHz). Findings: The frequency considered from 3.1 GHz-10.6 GHz produces omnidirectional patterns of radiations with simple geometrical configuration. Proposed design produces higher performance compared to the narrow band systems. Produces a better return loss in the entire UWB region Application/ Improvements: The applications include the dielectric, planar, wearable antennas and paying specific attention to the areas of portable devices such as laptops, tablets, wearable computers, glasses and mobile phones etc.
