I would like to express my sincere gratitude to my supervisor, Dr. Abas Sabouni for his guidance, patience and invaluable comments. Thank you very much, Dr. Sabouni for giving me the opportunity to pursue this project and for all your support, encouragement and guidance throughout this work.
My heartiest thanks and most profound appreciation is due to my parents, my wife, and my lovely sons (Meshal, Khalid, and Basel) for standing beside me, encouraging and supporting me all the time I have been working on this project.
Finally, I would also like to thank all the members of staff of Electrical Engineering and Physics Department at the University of Wilkes, for the active contribution while perusing my master degree, and for giving me the …show more content…

However, after integration, slight pattern distortion may be observed due losses in the solar cell.

4.6 Measurements
A prototype patch antenna is simulated and measured to explain the measurements procedure of a solar antenna for all configurations. The design layout of this patch antenna is illustrated in Figure 4-28. (a) (b)

4.6.1 Simulated and Measured S11 of Patch Antenna
Simulated and measured S11 of the designed patch antenna is presented in Figure 4 29. The return loss results reveal that this antenna has multi-band response which includes 1.31, 1.67, 2.37 and 2.83 GHz. The simulations and measurements are completely agreed and matched. (a)
