Thinned Antenna Array,hase shifts, but always with the same distances between the neighboring antenna elements with d = λ/2. Different amplitude weights and phase shifts were chosen, in order to form and steer the beams on one hand, and on the other hand to suppress the side-lobes.

Shun-Ping Chen,Heinz Schmiedel and simplified understanding of the basic principles of electromagnetics. Abstract theory has been explained using real life examples making it easier for the reader to grasp the complicated concepts. An introductory chapter on vector calculus and the different coordinate systems equips the readers
