Abstract

A wireless network system consists of several components that support communications using radio or light waves that propagating through an air medium. The coin antenna is used in wireless system that operates at the suitable frequency. There are many types of antenna which are microstrip, wire, array, dielectric resonator, reflector and so on. For this project, the coin antenna is related to the dielectric resonator antenna. This project is started by searching and finding all sorts of antenna theories and information, the existing coins of Malaysian Ringgit coins and find out the dielectric constant for each coin. After collect all the information that related to the antenna and coins, the calculation of designing the coin antenna can be started. The designing of the coin antenna will be continued by simulate the design that has been calculated. Then, the design will be continue by fabricate the design on FR4 board. The next step is measuring the parameters related to the coin antenna design by using Vector Analyzer which are return loss, resonant frequency, bandwidth and many more. The coin antenna met the specifications needed which operate at frequency of 2.4 GHz and the return loss that is below than -10 dB so that 90% power can be transmitted.
