Abstract

The development of wireless communication system often requires the device with compact size and light weight. To satisfy the requirement, the device should comprise of small parts, in which one of them is using printed antenna. Many researches on size reduction of printed antenna have been conducted. By using spiralresonator (SR) shape incorporated with matching circuit, in this paper, the size reduction of printed antenna is presented which is aimed to enhance the antenna performance. The proposed antenna is designed using two layers of1.6mm thick FR4 dielectric substrate with a proximity coupled technique applied as the feeding system. It is found that the proposed technique offered the proposed antenna to have the S 11 value of 25dB, the bandwidth of 40MHz, and the gain achievement of 2.3dBi. This is better than the performance of printed antenna without matching circuit which has the S 11 value of 15dB, the -10dB bandwidth of 30MHz, and the gain achievement of -0.5dBi. Moreover, the size of proposed antenna is reduced significantly up to 60% compared to the conventional patch antenna.
