Polymer-Based 3D Printed Sensors, Actuators, and Antennas for Low-Cost Product Manufacturing

Abstract

Modern wireless communication system plays a substantial role in day-to-day life. Wearable antennas are a key portion of wearable 5G communication applications, the Internet of Things (IoT), and biomedical systems. Compact efficient antennas considerably affect the performance of wearable systems. Wearable electronics and related technologies have gained tremendous traction in recent years. Several key developments contributed to increasing wireless communication's popularity, including the miniaturization of devices, the arrival of high-speed wireless networks, low-power, ultra-compact SoCs, and increasing battery performance. Various types of printed antennas are used in wearable electronics, which enable data to be sensed, retrieved, and exchanged wirelessly with a host device or an IoT gateway. The resolve of this chapter is to deliver the basic idea of flexible and wearable patch antennas and their fundamental concepts. Numerous types and methods have been deliberated in the current state-of-the-art field of the patch antenna. In this chapter, several wearable patch antennas are discussed that best suit modern-day wireless communication systems. Current challenges and limitations of the flexible and wearable patch antennas for modern wireless applications are discussed in detail with some possible suggestions.
