Abstract
Different radiation patterns will be induced by different excitation distribution in the antenna array. A coplanar waveguide fed coupling slot antenna array with Chebyshev excitation with equal side lobe level is investigated in this thesis.
Conventionally, to consider the mutual coupling between each element in an antenna array, we need to calculate the active impedance or admittance by calculating electric field or magnetic field first. This thesis proposes a systematic method combined with commercial software package to derive the active impedance. The major advantage is that it removes the need for calculation by field theory. After the active impedances are obtained, a CPW fed coupling slot antenna array can be designed with proper impedance matching.
Finally, a 4-element and 6-element CPW fed coupling slot antenna array with Chebyshev excitation are designed and fabricated to clarify the design method. From the simulated and experimental results, the design of the coupling slot antenna array is proved to be practical.
