“…To reduce the number of antennas in a transceiver system, the compact multiband antennas are of highest demand. Compact dual‐band antennas have been reported for the use of body area communications using multilayer structures, but these antennas show lower gain and efficiency in contact with the human body . In addition, the primary requirements of WBAN applications, the antenna should be designed by obeying the safety norms for radiation .…”

A dual‐band half‐mode substrate integrated waveguide (HMSIW) based cavity‐backed antenna is proposed for WLAN/WBAN applications at 5/5.8 GHz, respectively. A semi‐hexagonal slot is introduced on the top plane of the cavity primarily for radiation. This slot offers miniaturization for both the TM210 and TM020 modes. Later on, two rectangular slits are loaded on the open edge of the patch, to provide miniaturization and tuning mainly for the higher frequency band. The performance of the proposed antenna is investigated in free space and in proximity of the pork tissues. In free space conditions, the measured −10 dB fractional bandwidths are 3% and 3.1% along with peak gains of 6.25 and 6 dBi for the frequency bands at 5 and 5.8 GHz, respectively. In proximity of the pork tissues, the measured fractional bandwidth is 3.2% along with the efficiency of 81.5% at 5.8 GHz. The specific absorption rate (SAR) is 0.48 mW/g averaged over 1 g of tissues with 100 mW input power.

“…Subsequently has been proposed but again involving multiple feed ports. Single port microstrip antenna with dual polarization characteristics is realized using offset feeding and annular slot, parasitic patch, stacked patch, artificial magnetic conductor, and slot coupled power divider . Recent works have been reportedon realizing single port DBDP antenna using dielectric resonators, but thickness of dielectric radiator is still a major constraint of this technique.…”

This document presents a dual band dual polarized coplanar waveguide (CPW) antenna with single port feed. Lower resonating band is circular polarized, while the upper band is linear polarized. A novel concept of realizing dual polarization by suppressing the undesired modes is introduced in this work. Orthogonal Even/Odd modes are excited at lower band and a phase difference of 90° is maintained between them. Hence, circular polarization behavior is realized for lower operating band. For upper band, Odd mode is suppressed by introducing step shaped modifications in the ground plane at left side of the feed line, resulting in linear polarized upper band. Dual band nature of the antenna is confirmed by 10 dB impedance bandwidth extending from 3.91‐5.31 GHz to 7.51‐8.72 GHz. Circular polarized nature of lower band is confirmed by enclosure of lower band by 3 dB axial ratio bandwidth extending from 4.01 to 5.59 GHz. Advantages of proposed antenna involves the use of single port feed for generating dual polarization performance along with compact antenna size.(30 × 30 × 1.6 mm3).

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.
