Abstract :
In this work, the rectangular microstrip patch antenna and its arrays are analyzed using the Transverse Transmission Line (TTL) method along with the Transmission Line Model. Since the TTL is a full wave method and very much suitable for microwave components study, it gives accurate effective dielectric constant which contributes definitively to obtaining higher precision antenna parameters. For each type of array is calculated the array factor, considering the excitation, phase and the distance between the individual elements as well as the dimensions. Results for the radiation pattern in E and H-plane in 2 and 3D are presented
