Flexible Multi-Band Reconfigurable Modified Microstrip Antenna

A metal patch mounted at a ground level with a flexible di-electric material in-between constitutes a flexible Micro strip or Patch Antenna. The proposed antenna is a modified version of a microstrip antenna of 33x55 mm²on a flexible Kapton polyimide substrate. The antenna is tested using Vector Network Analyzer for different antenna parameters that provides multiband frequency at: 7.27 GHz, 10.61 GHz & 25.50 GHz covering C, X & K band respectively. A slot has been carved out of the antenna to divide the microstrip patch in two, which is connected using copper tape that acts as a switching diode to enable frequency reconfigurability of the multiband frequencies that have been measured. The impact of frequency peaks has been seen and studied with the reduction in bending radius from 50 mm to 30 mm.
