Abstract
In the field of health monitoring system, the design of wearable antennas provides global monitoring and communications. To meet the requirements of wearable antennas, properties like flexibility, cost and data transmission rate should be taken care. This paper represents the design and simulation for U-shaped slot rectangular microstrip patch antenna (RMSA) using high frequency structure simulator (HFSS) and analyzed their performance with different flexible substrates. The RMSA is designed using other flexible substrate materials such as Epoxy, Teflon, Polyethylene, polyamide, RT Duroid and PDMS to manage the operation frequency of 2.4–2.6 GHz. The parameters like reflection coefficient, bandwidth, radiation pattern, gain and cost of antenna are analyzed by keeping all substrates of same height. The proposed antenna in which PDMS is used as substrate material, found suitable for health and weight monitoring systems.
