ABSTRACT
열림/닫힘 버튼

In this study, a very efficient small antenna used in ISM band is designed and implemented. Additionally the desirable characteristic of the antenna is obtained by analysis and experiments. The suitable types of antenna are determined by considering the bandwidth, the electric field intensity of transmitter and receiver and the cell size. It is shown that the separation height between the patches plays a significant role in improving the impedance bandwidth of the antenna. An wideband technique is introduced to design a microstrip antenna to improve the narrow band characteristic. Two types of the microstrip antennas are implemented. The maximum bandwidth of the antenna with parasitic elements is obtained by repeating a number of experimental trials and referring to the analytic approximation formula.
