Design and Analysis of Flexible Polyethylene - Terephthalate Substratepatch Antenna Using Printing Technique for Conformal Application

Abstract

This intense research work represents a design of low cost inset feed rectangular microstrip patch antenna using PET substrate for 10 GHz frequency. It is focused on many applications, and high frequency RF device model explored and it demonstrates new fields of applications in communication and networking domains by its flexible behavior. This paper is dedicated to the enhancement of return loss, directivity and bandwidth at software generated resonant frequency 9.95GHz at given PET base design of conformal printed antenna & comparison in simulation and modeling with PET substrate. This design and simulation using High frequency structure simulator software (HFSS-15), the expansion of bendable concept provides the idea attaining different performance of EM radiations including better performance. Different Sections of research is described in broad way as followed the steps and achieved satisfactory results in the stream of flexible inset feed patch antenna for high frequency domain. A flexi ble Polyethylene terephthalate (PET) substrate highly mechanically robust, light weight, high bendability strength  with  well  deformability property. The antenna is feed by inset feed method and it is easy and provides good impedance matching. Here proposed structure antenna has been designed on PET substrate and operating frequency of the antenna is f=9.95 GHz, dielectric constant is 2.8, rectangular microstrip patch has dimension 8.9mm × 10.78mm and simulation results are illustrated for specific frequency allocated in particular applicationdomain.
