Silicon Wearable Body Area Antenna for Speech‐Enhanced IoT and Nanomedical Applications

Abstract

We propose in this paper a reduction in the size of wearable antennas on silicon (Si) for medicinal frameworks and Internet of things (IoT) in various nanoapplications. This research also introduces one more type of dynamic patch antenna designed in favor of speech-enhanced healthcare applications. The most significant impediment to the adoption of smart correspondence and medical services frameworks is voice-enabled IoT. The primary objective of a body area network (BAN) is to give ceaselessly clinical information to the doctors. Actually, wireless body area network is flexible, dense, trivial, and less expensive. On the other hand, the main disadvantage is low efficiency for small printed antenna. Microstrip silicon antenna recurrence is changed because of ecological conditions, distinctive reception apparatus areas, and diverse framework activity modes. By using tunable antenna, the efficiency of bandwidth usage can be increased. Amplifiers are associated with the feed line of antenna in order to build its dynamic range. In this study, a dynamic polarized antenna is constructed, analysed, and attempted for fabrication. The gain of the antenna is 13 ± 2 dB for the frequency range of 390 to 610 MHz. The output of the polarized antenna is roughly 19 dBm. At different environmental conditions, the performance and ability to control the antenna could vary. To achieve stable performance, we have used varactor diode and voltage-controlled diode. This silicon wearable antenna can be fabricated and tested for many medical applications like health monitoring system and pacemakers. Furthermore, micromachining techniques can be used to lower the practical dielectric constant of silicon and hence improve radiation efficiency.
