Abstract: This thesis presented the design of 5GHz antipodal linearly-tapered slot antenna (ALTSA) array using three-dimensional (3-D) finite element method (FEM). Both of single element and arrays of ALTSA with different parameters are studied. The printed ALTSA arrays have been implemented by using the FR-4 PCB substrate. For the single ALTSA, good agreements between simulation and measurement on input VSWR (about 1.3) and antenna directivity (about 12dBi) are achieved in the range of 5~6 GHz. For the ALTSA arrays, it could be found that, although with narrower HPBW, the directivity is slightly greater when the number of antenna element increases. But it could only be operated effectively in a narrower range of frequency (5.7~5.85GHz). There exists a trade-offs between antenna gain and bandwidth. The designed single element and arrays of ALTSA can be used for 5GHz communication system , such as the local point to point transmission between the buildings.
