碩士 === 國立彰化師範大學 === 電子工程學系 === 105 === This thesis presents the design of a broadband high-gain square microstrip antenna array of 22 elements integrated with reflector dish antenna for long distance point-to-point wireless communications. The square microstrip antenna array with the suspended air substrate structure can effectively increase the impedance bandwidth. As we want to have both of vertical and horizontal polarizations, this microstrip antenna array has two independent feeding networks with feeding points at orthogonal edges for each microstrip elements. However, the arrangement of orthogonal feeding edges of each microstrip element will affect the current distributions; thus, the radiation patterns will be tilted with an angle. Finally, this antenna array is used as an excitation source of reflector dish antenna to get higher directivity for long distance point-to-point wireless communication.
