| Popis: | 101 In this thesis, the designs of circularly-polarized (CP) high-gain green antennas using solar module as frequency selective surface (FSS) for Fabry-Perot (F-P) cavity are presented. First, the analysis of the transmission and reflection coefficients of the square solar cell is adopted for predicting the resonant frequency of the circular polarization and high gain operation. Next, the green antenna is constructed, and consists of a circularly polarized patch antenna (radiating source) backed with a metal ground plate and a square solar module of 6 6 (or 8 8) solar cells. The effects of the resonant height, the rotating angle of the radiating source, and the dimension of the square solar module on the impedance bandwidth, the CP bandwidth, and the realized gain of the green antenna are investigated. For the case of the green antenna excited by a CP radiating source operated at the center frequency of 3.0 GHz, the achieved impedance bandwidth is 154 MHz (2.928 ~ 3.082 GHz), the CP bandwidth is 76 MHz (2.907 ~ 2.983 GHz), and the antenna gain within the CP band is 13.0 ~ 13.9 dBic. Furthermore, the green antenna excited by the radiating source operated at the center frequency of 3.5 GHz is also studied, the antenna gain within the CP band (88 MHz, 3.434 ~ 3.522 GHz) reaches to 16.0 ~ 18.6 dBic. |
