Design of reconfigurable dual-band E-shaped microstrip patch antenna

Abstract

A novel compact size of reconfigurable E-shaped microstrip single patch antenna was designed and analyzed for dual-band at 3.02 GHz and 6.38 GHz frequencies. The basic antenna was designed to operate at 3.02 GHz and with reconfigurability in frequency, it will operate at 6.38 GHz. The physical parameters of the novel structure as well as its partial ground plane will be analyzed and optimized using commercial computer simulation technology (CST) packages. Return loss (S <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">11</sub> ), voltage standing wave ratio (VSWR) and gain will be carried out. The return loss of the optimized reconfigurable E-shaped microstrip patch antenna has to be less than -10dB at 3.02 GHz and 6.38 GHz frequencies band. The reconfigurable antenna was then to be measured by vector network analyzer (VNA) to carry out its S <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">11</sub> and VSWR result. The result from simulation and measurement will be compared. The proposed antenna is very promising for various modern communication applications such as wireless and satellite application.
