Design and Analysis of Dual Band Micro strip Patch Antenna

Sethi, Sujeet Kumar (2015) Design and Analysis of Dual Band Micro strip Patch Antenna. BTech thesis.



This thesis involves the design and analysis of Dual band Microstrip patch antenna which operates at lower and upper resonating frequency of 3.05 GHz and 7.24 GHz respectively. Basically transmission line modelling approach has been used to model the antenna. The proposed antenna has been fed with 50O microstrip feed line. In the first frequency band we have bandwidth of 310MHz (2.91-3.22 GHz) with gain and directivity 3.304dB and 4.393dBi respectively. The second frequency band has a bandwidth of 580MHz (6.69-8.27 GHz) with gain and directivity of 3.534dB and 5.516dBi. Radiation efficiency at the two bands of operations are 75.12% and 63.52% respectively. Design parameters for the proposed antenna have been calculated from the transmission line model equations considering the effects of introducing inset notch parallel to the radiating edge of the antenna. Ground plane dimensions have been optimized by analyzing the antenna characteristics through parametric study. The CST Microwave Studio software has been used to implement the desired design and various antenna parameters have been studied. Furthermore, an attempt has been taken to calculate the return loss vs frequency response through MATLAB coding. The proposed antenna covers a good portion of S-band and C-band. It can be embedded in mobile devices for the purposes of mobile WiMAX, Wi-Fi, Bluetooth and WLAN operations due to its very small size and weight. Also it can be used by weather radar, surface ship radar, and some communications satellites for various surveillance and communication purposes
