Abstract
In this paper, a conformal body centric antenna for wireless body area network (WBAN) applications is discussed. These designs are low-cost, low-profile circular and ring-shaped monopole antennas. Operational frequency of antenna is range from 2.5–10.6 GHz to meet the requirements of WBAN systems. The antenna is intended to be body- centric and conformal, which means for best performance, it is placed close to the body and conforms tothe shape of the human body. The radiation patterns are measured at 2.5 Ghz frequency. The substrate used for design is FR-4. The simulation results show that the proposed antenna has good impedance matching, a broad bandwidth of 122 MHz, and a gain of 4.8 db. The radiation pattern of the antenna is omnidirectional, which is desirable for wireless communication applications. Monopole antenna is designed and simulated using the Ansys EDT (HFSS) software. The monopole antennas are also fabricated in real time with proposed specifications. The proposed antenna can be used in various wireless communication systems such as WLAN, RFID, and Bluetooth, where low cost, compact size and critical design are considered.
