Objective: The different configurations of hexagonal monopole antennas are designed, simulated, tested and their performance is compared. Method: Different Hexagonal monopole antennas are designed and simulated using HFSS, these antennas are designed using Defective Ground Structure (DGS) and slots are made in ground plane and on patch. Effect of slot position on performance of antenna is examined. The antenna units are studied through simulation two antennas were fabricated and its return loss and VSWR are measured. Findings: The antenna parameters like return losses, VSWR, Gain and Directivity are evaluated and return losses and VSWR for the fabricated antennas are measured. It is observed that over a wide frequency band the return losses are <10 dB and VSWR is less than 2. Applications: These antennas can be used over UWB for Wireless and Indoor applications.Keywords

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.References
