The purpose of the project is to design a quarter wavelength antenna with an operative frequency of 433MHz for optimum power transfer. This report serves as a write up on the investigations we have carried out as well as to provide a brief discussion on the antenna we plan to design. An antenna is a circuit element or electrical conductor which transforms a guided one dimensional Electromagnetic (EM) wave in the transmission line into a freely propagating EM wave in three dimensional spaces with specified directional characteristics. Antennas have two operative modes: transmission and reception. During transmission, EM waves are being radiated out by the antenna whereas in reception, an antenna receives EM waves and converts them back into electrical signals. Antennas are calibrated for optimum performance simply by introducing slight changes in its length or by tuning its fundamental shape. Calibration is usually done at the later stages of antenna design and has an appreciable effect on the performance and characteristics of an antenna.
