“…WBAN communication links can be divided into off-body, on-body, or in-body links, and different links have different antenna design methods [3]. 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].…”

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.

“…For the off-body link, an antenna is placed on the body to communicate with external devices or systems. Such antennas require the radiation pattern normal to the body surface [4] and the features of small size and robust on-body performance. Besides, multi-band and broadband antennas are preferable options to realize multiple functions.…”

“…Several broadband and dual-band antennas have been presented [4][5][6][7][8]. A dual band antenna consisting of a shorted annular ring and circular patch is proposed in [4] to realize dual-mode radiation patterns. A similar design is presented in [5] with height of about 13 mm.…”

A novel compact dual-band antenna for wireless body-area network (WBAN) is presented. The miniaturization is realized by bisecting a quadrant circular microstrip antenna along the fictitious magnetic wall, while the electric field distribution at 2.45 GHz is preserved. By slitting an open-ended quarter-wavelength slot, a second resonant mode at 5.8 GHz is excited. The proposed antenna is fabricated and measured both in free space and on-body. Enhancement in bandwidth and radiation patterns is observed for on-body performance compared with that in free-space. Measured fractional bandwidths of 1.2% and 2.0% are obtained at the two bands respectively when the antenna is mounted on-body, along with the corresponding simulated radiation efficiency values of 60% and 76%. The robust on-body performance reveals the proposed antenna a good candidate for low data-rate WBAN applications.Index Terms-Wireless body-area network (WBAN), dual-band, compact, on-body performance.

“…Diverse radiation patterns are required in the antenna designs to achieve multi-function and several designs are proposed [1][2][3][4][5][6][7][8][9]. Circular patch antennas with a thick shorting pin in the center support TM11 and TM01 modes simultaneously, thus both unidirectional and omnidirectional radiation patterns can be generated by one patch [1].…”

“…In [5], a stacked-patch antenna fed by one probe is proposed, where the lower patch shorted by four metallic pins operates at TM01 mode with conical beams and the upper patch operates at TM11 mode with broadside radiation patterns. The combination of annular ring patch antennas and small patch antennas inside offers an alternative solution, as the annular ring patch can generate omnidirectional radiation patterns and the patch inside radiates unidirectionally [6,7]. A similar design consisting of an outer square ring patch and an inner patch is proposed in [8], while the operation mechanism is different.…”

In this paper, a novel dual-band antenna covering 2.4/5.8 GHz industrial scientific medical (ISM) bands is presented. At the lower band, a circular monopolar patch antenna with four symmetric slots is designed for omnidirectional radiation. At the upper band, a U-slot square patch antenna is designed for broadside radiation. By assembling the two antennas and feeding them with a common coaxial probe, the two resonant modes are preserved and the upper frequency bandwidth is broadened. A prototype is fabricated and measured. Measured bandwidths of 115 and 928 MHz and gains of 1.37 and 4.37 dBi are obtained at 2.45 and 5.8 GHz bands, respectively. The measured results agree well with the simulation, indicating that the proposed design is suitable for diverse wireless communication applications.Index Terms-Dual-band, dual-mode, monopolar patch antenna, U-slot antenna.
