<p class="Abstract">In this study, a compact quarter-mode substrate integrated waveguide (QMSIW) based dual-band antenna is proposed for wireless body area network applications. A QMSIW resonator is realised by splitting the full-mode substrate integrated waveguide cavity along the perfect magnetic conductor walls. The proposed antenna preserves the fundamental mode TE110 and the third order mode TE220 of the square SIW cavity. The proposed antenna is linearly polarised in the lower band at 2.45 GHz and circularly polarised in the higher frequency band at 5.8 GHz. The on-body performance of the antenna is validated on a piece of pork muscle tissue and it has been found to be stable with respect to surroundings. The proposed antenna covers the ISM bands 44 MHz (2.445 GHz - 2.489 GHz) and 225 MHz (5.730 GHz - 5.955 GHz) at 2.45 GHz and 5.8 GHz, respectively. The measured gain of the antenna on pork tissue is 1.87 dBi and 5.5 dBi at two bands. In addition, the specific absorption rate is obtained of 0.65 mW/g and 1.51 mW/g at two bands (wext = 2 mm), averaged over 1 g of muscle with 100mW input power. Moreover, the simulated and experimental results demonstrate a good agreement.</p>

A dual-band on-body antenna for a wireless body area network repeater system is proposed. The designed dual-band antenna has the maximum radiation directed toward the inside of the human body in the medical implantable communication service (MICS) band in order to collect vital information from the human body and directed toward the outside in the industrial, scientific, and medical (ISM) band to transmit that information to a monitoring system. In addition, the return loss property of the antenna is insensitive to human body effects by utilizing the epsilon negative zeroth-order resonance property.

A dual-band on-body repeater antenna for in-on-on wireless body area network applications is proposed. The proposed antenna has a maximum radiation normal to the human-body surface for communication with implanted devices in the 5.8 GHz industrial, scientific, and medical (ISM) band. In addition, to transmit the biological information received from the implanted devices to other on-body devices, the proposed antenna was designed to have a monopole-like radiation pattern along the surface of the human body for communication in the 2.45 GHz ISM band. The antenna was fabricated, and its performance was measured by attaching it to a human-equivalent semisolid phantom. In addition, the human-body effect was studied to ensure antenna performance under an actual situation.

This paper is formulated keeping in view the need of compact antennas for wireless body area network (WBAN). The designed compact dual-band antenna (20[Formula: see text]mm [Formula: see text] 22[Formula: see text]mm [Formula: see text] 3.55[Formula: see text]mm) radiates at two resonant frequencies in the ultra-wideband (UWB) range. Compactness in the designed antenna is attained by using three different layers of copper and the return loss and gain characteristics are improved by incorporating a G-shape defected ground structure (DGS). The proposed antenna is unidirectional and immune to human contact since it is designed in the UWB range (3.1–10.6[Formula: see text]GHz) which makes it highly suitable for WBAN applications as its low radiating power is harmless for human tissues. The substrate used for design is RT/duroid with a relative permittivity of 2.2. The antenna exhibits superior frequency domain characteristics with simulated [Formula: see text] of [Formula: see text]16.39[Formula: see text]dB for 4.08[Formula: see text]GHz and [Formula: see text]21.87[Formula: see text]dB for 8.18[Formula: see text]GHz and realized gain of 3.69 and 6.02[Formula: see text]dB for 4.08 and 8.18[Formula: see text]GHz, respectively. The measured [Formula: see text] depicts a shift to the lower band for the fabricated antenna with the values of [Formula: see text]15.36[Formula: see text]dB for 3.55[Formula: see text]GHz and [Formula: see text]21.66[Formula: see text]dB for 6.218[Formula: see text]GHz.

This paper presents a new design of patch antenna using Minkowski-Sierpinski fractal technique with substrate integrated waveguide (SIW) to resonate at 60 GHz. The antenna is proposed to be used for wireless body area network applications (WBAN). The proposed antenna is implemented using Rogers 5880 substrate with permittivity of (εr) of 2.2 and loss tangent is 0.0004, height of the substrate is 0.381 mm. Computer simulation technology-Microwave Studio (CST-MW) is used to simulate the proposed antenna. The simulated results show a wide bandwidth of 3.5 GHz between the ranges of (58.3-61.7) GHz, with a good return loss of more than -10 dB. A simulated gain of 7.9 dB is achieved with a linear antenna efficiency of 91%. This proposed antenna is used to improve the quality of radiation pattern, bandwidth, and gain at millimetre wave (mm-Wave) band for WBAN applications.

Dual Band Antenna

Wireless local area network (WLAN) communication is one of the fast and secure wireless technologies, which is vastly used in nowadays portable and handheld devices. This paper is oriented on designing of a planar WLAN antenna to serve in WLAN network devices. The designed antennas are single and dual-band planar monopole antennas to be working at IEEE 802.11 WLAN frequencies; 2.45 GHz and 5.2/5.8 GHz bands. Different configurations have been used in the design process, especially for the dual-band antenna, where dual-resonant is required. The antennas have been designed analytically then simulated using the CST software package. Simulation results for the input reflection coefficient, realized gain, and radiation pattern have been considered to evaluate their features. The antennas have also been fabricated practically and practical measurements for the input reflection coefficient and radiation pattern have been taken which shown a good agreement with those of simulation.
