Abstract
A novel dual-band and diverse radiation pattern antenna is proposed for power efficient on-body and off-body communications intended for various applications in healthcare and sport monitoring. The antenna is dual band at 2.45 GHz (ISM band) with omnidirectional radiation pattern over the body surface to communicate power efficiently with other co-located body worn devices and at 1.9 GHz (PCS band), it has directive radiation pattern towards off the body to communicate from on-body device to off-body devices. The free space and on-body performances of the antenna are investigated by both simulation and experiment. The antenna shows very good on-body radiation efficiency of 58% at 2.45 GHz and 61% at 1.9 GHz. Good on-body gain is noticed at both frequency bands. Results show that the gain of the proposed antenna increases by 4.7% at 2.45 GHz and 3.2% at 1.9 GHz when placed on the body.

Body-centric wireless communications (BCWCs) are a central point in the development of fourth generation mobile communications [1]-[3]
In common healthcare monitoring scenarios, it is very important for the antenna to radiate over the body surface omni-directionally and directive towards off the body units in order to get the best on-body and off-body radio channel performances i.e. minimising the link loss to ensure power effi

Summary
Body-centric wireless communications (BCWCs) are a central point in the development of fourth generation mobile communications [1]-[3]. (2014) Wearable Antenna for Power Efficient On-Body and Off-Body Communications. Alomainy et al [7]-[9] presented various wearable antennas in the 2.4 GHz (ISM band) for on-body communications. In [10], Scanlon et al presented a set of higher mode microstrip patch antennas operating at 2.45 GHz for over the body surface communications. Antenna radiation pattern influences the on/off-body radio channels performance. To the author knowledge nothing has been performed in designing of antenna for power efficient on-body and off-body communications with different radiation modes at different frequencies. A dual band and diverse radiation pattern antenna is proposed for power efficient and reliable cooperative on-body and off-body communications. The free space and on-body performance parameters of the proposed dual band and diverse radiation pattern antenna are investigated by both simulation and experiment. The rest of the paper is organized as follows; Section 2 illustrates the antenna design, Section 3 presents result and analysis, and Section 4 draws the main conclusion
