This paper summarises a novel microstrip patch antenna design over flexible Teflon substrate having dielectric constant Îµr= 2.1. The proposed antenna exploits a King shaped slot (0.05mm thick) on the radiating patch along with microstrip feed line and reduced ground plane on the other side of the substrate. The radiating element of the flexible flanged antenna design has a King-shaped slot and a finite ground plane to accomplish an excellent impedance matching for maximum power transfer. The proposed antenna has an operating bandwidth of 550.7MHz (3.1244GHz-3.675GHz) with resonant frequency at 3.42GHz and has also an operating bandwidth of 369.1MHz (8.3507GHz-8.7198GHz) with resonant frequency at 8.3609GHz. This flexible flanged microstrip patch antenna design covers various applications including Radio astronomy/ Radiolocation (military&civil)/ UWB/PMSE/FSS Earth stations applications (3.3GHz-3.6GHz), Radio-determination/ Space-research/Fixed applications (8.4GHz-8.5GHz), activesensors (satellite)/ Radiolocation (civil&military)/ Aeronautical-navigation applications (8.5-8.55GHz). The proposed antenna operates for acceptable voltage standing wave ratio (VSWR) less than two. The characteristics of the proposed antenna fabricated on a flexible Teflon with different bending angles have been successfully measured. The antenna has been designed in CST Microwave Studio 2014. The proposed antenna has been fabricated and tested using E5071C Network analyser and anechoic chamber. It has been observed that the simulated results legitimately match with the experimental results.
