A Compact Flexible Frequency Reconfigurable Antenna

The main aim of our project is to design a frequency reconfigurable antenna with a good gain compared to the existing model. Our proposed antenna will provide a max gain at high frequency. In mobile phone there are three to four antennas are used. Because of this the cost for buying antennas are huge. A huge amount has to be spent to buy antennas and fix it in the mobile phones, so a single antenna canactin different frequency is a best solution for the problem. It is given, a small, flexible frequency reconfigurable antenna. The flexible Rogers RT/duroid5880 substrate, which measures just 30 × 28.4 × 1.5 mm
³
, is used in the suggested design. With its two surface-integrated switches by changing the current distribution and, the resonance frequency using various switch situations, this antenna may be reconfigured for a different frequency. The antenna is being stimulated using CST. Over the intended frequency ranges, The stimulated antenna using CST shows notable radiation patterns with maximum gain value of 3.06 dBi and VSWR < 2 used in mobile applications.
