Abstract :
The transverse transmission line (TTL) method is used for the analysis of the microstrip phased antenna array. The TTL method is efficient and accurate for the analysis and design of rectangular microstrip antenna arrays. It is a very versatile method that can be used with a lossless, a lossy or a semiconductor substrate in various planar structures. The antenna phased array is shown to be very efficient and may be used in several applications. Radiation diagrams are presented in 3D for microstrip antenna arrays. It is observed that the variation of phase excitation has a great influence on the array, including modifications of the radiation pattern.
