Hariharasubramanian 2 Electronics and communication Engineering Kalasalingam Institute of Technology Krishnankoil, Tamilnadu, India [email protected]Abstract— In this project, a two element microstrip patch antenna is constructed to support the Body Area Network and to monitor the Body conditions. In the proposed design of the antenna, Microstrip feed is introduced. Two C shaped antennas are placed. The substrate material to be used is Denim-a light weight soft surface material. The antenna works at the frequency range of 5.5 GHz of C Band application and 9 GHz of X Band application. Since it works on OFF- Body mode, it produces Broadside radiation pattern and its purpose can be extended to a wide range such as Body Centric Wireless purposes such as Navigation, Health monitoring and C Band Satellite Communication. Keywords— Body Area Network (BAN), OFF-Body mode, C Band antenna, wearable antenna, textile antenna, communication antenna. I. INTRODUCTION Antenna is a major critical component of the wireless communication system, which is a key building block for constructing every wireless communication systems. Recently there are many advanced technologies in the field of wireless technology. Though there are many types of antennas present, the Microstrip patch antennas are highly used in the wireless Body Area Networking (BAN) applications in which numerous nodes are placed near to the body region. Microstrip antenna is also known as printed antenna. It plays a vital role in wireless communication field. Microstrip antennas are simple to construct by using fabrication technique. This type of antennas is now used in designing textile antennas. These antennas consist of a radiating patch on top of the dielectric substrate and also have a ground plane on the bottom side. Two element antennas are a combination of two antennas with a single junction. These two elements array works together as a single antenna for transmitting the input signals. It is capable of producing high Gain and Directivity. The existing antenna is a square shaped body centered antenna at a size of 80 millimeter on all sides. It is a patch antenna with two coaxial feeds designed for the purpose of Body Area Communication and tracking the activities of the human body. It works at a given frequency of 2.45GHz of ISM (Industrial, Social and Medical) applications and works on Dual bands. A new patch antenna which is proposed is a C Shaped antenna with Microstrip feed. It works only in OFF- Body mode. The proposed antenna works at a frequency range of 5.5 GHz of C Band application and 9 GHz of X Band application. It produces Broadside radiation pattern and is used for Body area Wireless Networks. II. ANTENNA DESIGN METHODOLOGY The Proposed antenna design is shown in the Fig. 1. There are two antennas of C shaped and Square structured with a microstrip patch on the bottom. Here the Ground layer is defined as the infinite or boundary less region. The ADS 2011.05 (Advanced Design System) Software is used to design the proposed antenna. In this software the 3D radiation pattern is obtained and the output parameters are easily calculated. The shape of the antenna is obtained by assigning the coordinate values for each part.
