| Popis: | Recently many antennas has widespread concern about the use of wireless on-body application. In this paper, different types of small-sized microstrip line-fed antennas were designed with flexible materials to achieve deeper penetration of signals into the human body. The proposed compact square spiral antenna is designed on low cost FR4 substrate of thickness 1mm as such reduce the fading and allows the antenna to steer the maximum gain. Return loss and mutual coupling characteristics was investigated under different relative conditions when placing the antenna on phantom layer. It shows stable radiation patterns throughout the frequency range of 2GHz to 4GHz which results in improvement of significant gain along with increased directivity. |
