Abstract-This paper proposes a novel, low-profile UWB antenna for wireless body area network (WBAN) applications. The antenna has a polarization perpendicular to the body-free-space interface, which is interesting in order to minimize the coupling into the body. Its structure comprises a modified mono-cone with a top-cross-plate and is coaxially fed through the ground plane. The higher frequency band performance is due to the mono-cone while the top-cross-plate is responsible for the lower frequency band. This plate also leads to a height reduction when compared to conventional mono-cone antennas. A comprehensive parametric study is done to provide design guidelines. Both frequency-and time-domain results have been measured and presented to validate the design. Results show that the antenna operates from 3.06 to beyond 12 GHz based on dB, radiates omni-directionally in the -plane, and has a radiation efficiency over 95%. The system-fidelity factor for UWB signals is adequate for pulse transmission. Finally, the influence of the human proximity on the antenna matching was tested. Results show that its impedance is nearly unchanged as compared to free-space.Index Terms-Frequency-and time-domain, low profile, UWB antenna, vertically polarized, wireless body area network.

“…For on-body links, antennas are typically designed as Planar Inverted-F Antennas (PIFAs) [4], patch antennas [5], folded antennas [6], slot antennas [7], or just electrodes [8]. In order to attach to the human body, the antenna structure should be small-size and low-profile, and its communication performance should be low interference with other antennas [9].…”

A dual-band coil antenna for MHz band on-body wireless body area networks

Abstract:A dual-band coil antenna is proposed for MHz band on-body Wireless Body Area Network (WBAN) applications by near-field coupling, with relatively low attenuation from the human body. The proposed antenna has two operating frequencies at 48.2 and 57.6 MHz with the measured -10-dB bandwidth 47.9 -48.6 MHz and 57.1 -58.2 MHz, respectively. Matching circuits are used to reduce the antenna size and tune the resonant frequencies. A human phantom is used for the antenna simulation and measurement. Reflection and transmission coefficients and electric and magnetic field distributions of the proposed antenna are shown, and 1-g and 10-g average Specific Absorption Rate (SAR) and the maximum safety input power are calculated to evaluate the antenna's radiation safety.

“…Recently, several UWB antennas have been reported [1][2][3][4][5][6][7][8][9]. The typical shapes of these configurations are circle [1][2][3][4], rectangle [5][6][7], and folded shape [8,9]. Using coupled parasitic elements and etching different kinds of slots on the patch or ground are the common methods to realize bandnotched performance.…”

Abstract-A compact printed ultra-wideband (UWB) antenna with band-notched characteristic is proposed. The presented antenna consists of a modified ground plane structure and a novel C-shaped radiation patch fed by a microstrip line. By etching a C-shaped slot in the radiating patch, the notched band of 3.3-3.8 GHz for WiMAX is generated. The notched band can be easily tuned by controlling the size of the slot. The measured results show that the proposed antenna operates over a wide bandwidth from 3 GHz to 16 GHz with return loss less than −10, except a stop-band of 3.3-3.8 GHz. Some key parameters of the antenna are discussed in details. The time-domain characteristics are given.
