| Popis: | 97 From previous studies, it was found that a capacitor-loaded patch antenna could radiate at frequency much lower than traditional patch antenna. This allows the capacitor-loaded patch antenna to be used in the area that was previously not possible. In general case, the larger the loaded capacitance or the further away from the center, the dominant operation frequency can be decreased. In antenna design, it is usually desirable that one could use a simple formula to handle the parameters, such as the loaded location, the patch size, and the capacitance, so that one can predict the behavior of the antenna under these parameters. The circular patch antenna with only the radius of the patch as the parameters seems to be a good candidate for this type of unified formula study. In this thesis, the operating frequency of a capacitance loaded circular patch antenna can be maximized operate at about 1/3 of the original frequency. In addition, a model is developed to predict the behavior of circular patch antennas when capacitance is loaded at certain location of the patch antenna. |
