Abstract :
This paper presents a printed dual band antenna with a full ground plane and electromagnetically coupled feed for body area network devices operating in the industrial, scientific, and medical (ISM) band at 2.45 GHz and 4.9GHz public safety Wireless Local Area Networks (WLAN) band (4.94-4.99GHz). Performance along with parametric analyses are presented. Investigations have been carried out to assess its performance for body centric wireless communication. The electromagnetically-coupled feed is tuned to fill a null in the radiation pattern and to achieve impedance matching. The proposed antenna exhibits a wide radiation pattern along the body surface to provide maximum coverage and its narrow width (14mm) makes it suitable for on-body applications.
