Abstract

With the rapid increase in the wireless communication, miniaturized, compact and low profile antennas are a urgent need for wearable antenna applications.In this paper a coplanar waveguide (CPW)-fed circular monopole antenna is designed using Ni?.?Zn?.?Fe?O?–linear low-density polyethylene (LDPE) magneto-dielectric composite substrate. The magneto-dielectric material enables antenna miniaturization and reduces the influence of the human body on antenna performance. The radial stubs enhance the performance of the antenna. The antenna is designed and fabricated to operate in 6 GHz and reflection coefficient (S??) of ?24.31 dB at 5.27 GHz and ?10 dB bandwidth of 21.44% is observed

Introduction

The paper presents a compact wearable antenna design to meet the growing demand for miniaturized wireless communication devices. It proposes a CPW-fed circular monopole antenna built using a Ni?.?Zn?.?Fe?O?–LDPE magneto-dielectric composite substrate, which helps reduce antenna size and minimize human body effects on performance. Radial stubs are used to improve overall efficiency. The antenna operates around the 6 GHz band, achieving strong performance with an S?? of −24.31 dB at 5.27 GHz and a −10 dB bandwidth of 21.44%, making it suitable for wearable applications.

Conclusion

CPW fed circular monopole antenna with radial stubs is developed and designed on the Ni?.?Zn?.?Fe?O?–LDPE magneto-dielectric composite substrate for wearable application. Reflection coefficient (S??) of ?24.31 dB at 5.27 GHz and ?10 dB bandwidth of 21.44% is observed for the designed antenna. Magneto-dielectric composite as substrate miniaturizes the antenna and enhances the overall performance of the antenna.The compact shape enhances the low profile of the antenna and makes it suitable for wearable antenna applications.
