| Summary: | 碩士 === 國立臺灣大學 === 電信工程學研究所 === 99 === A concept for designing a broadband aperture-coupled microstrip patch antenna is presented in this thesis. The proposed patch antenna is fed by a coupling aperture, offset from the patch center. This generates a fictitious open circuit within the resonating edges of the patch, and therefore, an additional resonant frequency is produced and a wide impedance bandwidth can be obtained. Also, a broadband patch array using the patch as its radiating elements is presented. All the designs are fabricated and verified via both measurements and simulations. Then, the proposed patch array is integrated with an off-the-shelf power amplifier module, and the power density radiated by the system is further characterized. Finally, this system is used as a microwave virus sanitizer to eliminate the H1N1 viruses, and a series of experiments is setup and performed. The associated results are also presented.
