This paper encapsulates a novel microstrip patch antenna design over flexible Teflon substrate having dielectric constant εr= 2.1. The designed antenna exploits a rectangular patch (0.05mm thick) on the radiating patch along with microstrip feed line and defected ground plane on the other side of the substrate. The radiating element of the flexible flanged antenna design has a finite ground plane to accomplish an excellent impedance matching for maximum power transfer. The proposed antenna has an operating bandwidth of 2.9226 GHz which ranges from 15.197GHz-18.12GHz with a resonant frequency of 15.72GHz. This flexible flanged microstrip patch antenna design covers various applications including Radio Astronomy (15.35GHz-15.4GHz), Radiolocation/Airborne Doppler navigation aids (15.4GHz-15.43Hz), Radiolocation(civil)/Airborne Doppler navigation (15.43GHz-15.63GHz), Radiolocation(military) (15.7GHz-17.7GHz), FSS Earth Stations (17.7GHz-20.2GHz), Weather Satellite(18.1GHz-18.3GHz), Broadcasting(Satellite) (21.4GHz-22GHz). The proposed antenna operates for acceptable voltage standing wave ratio (VSWR) less than two. The characteristics of the proposed antenna fabricated on a flexible PVC and analyzed its performance at different antenna parameters like Return loss (dB), Impedance Bandwidth, Gain(dB), Directivity(dBi), VSWR and antenna impedance. The antenna has been designed in CST Microwave Studio 2014. The proposed antenna has been fabricated and tested using an E5071C Network analyser and an anechoic chamber. It has been observed that the simulated results, legitimately match with the experimental results.
