Abstract :
The TTL (transversal transmission line) method is applied to the analysis of patch resonator, as a planar antenna. A set of equations that represents the electromagnetic fields in the x and z direction as function of the electric field in the y direction are obtained. This method is very suitable at microwave and antenna applications, and gives accurate complex resonant frequency which contributes to obtain higher precision antenna parameters. For each type of array is calculated the array factor, considering the excitation, phase and the relative displacement between the elements as well as the dimensions and number of elements.
