Microstrip Antenna in IoT

Abstract

Internet of Things is described as an infinitude of embedded devices and small sensors, integrated in a wide network with a permanent access to the user. One of the major applications of IoT is in the smart home/office concept, allowing more convenience, efficiency (with at additional aspects), and security. Nowadays, with numbers of devices, it is mandatory for these devices to be small, low-power, and at the same time more capabilities and efficiencies. In this paper an antenna is proposed for IoT devices, developed for 17 GHz band and presenting high bandwidth according to the growing needs of wireless networks. This antenna has reduced dimensions, ideal to be integrated in most IoT sensors. For future wireless communication, low cost, low profile, minimal weight, and high performance antenna is required to support high speed data transmission. This paper presents a graphene based wideband microstrip patch antenna at 1.10 THz resonate frequency. Graphene has been used in the proposed antenna for higher electrical conductivity, mobility, and saturation severity in THz band regime. The proposed antenna is mounted on Silicon substrate that employed Photonic Band Gap (PBG) having a dielectric constant of 11.9. The outcome of this work has been described in terms of return loss (S11), gain, directivity, voltage standing wave ratio (VSWR), radiation efficiency, and radiation pattern in E-plane. The proposed antenna has obtained minimal return loss 48.95 dB, gain 3.97 dB, VSWR 1.054 and bandwidth 26% which may be an excellent candidate for advanced wireless communication systems. All the designs and simulations are performed based on the finite integration technique with the commercially available CST Microwave Studio simulator tools with diverse process.
