“…The proposed antenna offered omnidirectional radiation pattern characteristics over 2.4 -13 GHz operating frequency range. Tan et al [73] introduced a miniaturized planar UWB slot antenna with dual-polarization MIMO with overall antenna dimensions (32 × 22) mm 2 printed on inexpensive FR4-epoxy substrate εr = 4.6, δ = 0.02 and h = 0.8 mm. The efficiency of the UWB impedance was obtained using phased slots of one-quarter of wavelength.…”

Ultra-wideband (UWB) technology can offer broad capacity, short-range communications at a relatively low level of energy usage, which is very desirable for wireless body area networks (WBANs). The involvement of the human body in such a device poses immense difficulties for both the architecture of the wearable antenna and the broadcast model. Initially, the bonding between the wearable antenna and the human body should also be acknowledged in the early stages of the design, so that both the potentially degrading output of the antenna as a consequence of the body and the possibility of exposure for the body may be handled. Next, the transmission path in WBAN is affected by the constant activity of the human body, leading to the time-varying dispersion of electromagnetic waves. Few researchers were interested in this field, and some substantial progress has recently been considered. On the other hand, this paper covered both wearable and Non-wearable UWB antenna designs and applications with respect to their substrate characteristics. Finally, this review prospectively exposes the upgraded developments of (ON-OFF) body antennas in the area of wearable and Non-wearable UWB and their implementations in the WBAN device and aims to evaluate the latest design features that inspire the performance of the antennas.INDEX TERMS ON-body antenna, OFF-body antenna, wearable antenna, ultra-wideband (UWB) antenna, wireless body area network (WBAN).

“…Apart from that, the reason why we adopt the excitation of slot coupling to the DD patches antenna is the same as that of DRA, utilizing slot mode and DD patches mode can simultaneously widen the bandwidth of the DD patches antenna. [12][13][14] Compared with DRA and DD patches, stacked patches, [21][22][23][24][25] crossed dipoles, 26,27 and slot antennas [28][29][30][31] have more mature theories, so these are also more popular solutions when designing dual-polarized antennas. However, due to its own limitations, it is difficult to achieve wideband, and the gain is low.…”

A dielectric‐loaded slot antenna with the characteristic of broadband, low profile, and low cross‐polarization is presented. The antenna incorporating a low permittivity () and multiple high permittivity () rectangle dielectric is fed by two rectangle slot, which generates three slot modes and achieves measured 10 dB impedance bandwidth of 88 from 1.57 to 4.04 GHz covering the long term evolution (1.71–2.69 GHz) and sub‐6G (3.3–3.6 GHz). Furthermore, the presented slot antenna with a footprint of 0.81 × 0.56 and a low profile of 0.09 ( is the wavelength in the air region at the center frequency) appears the performance of measured peak gain of 9 dB without using any dielectric resonator mode. On the basis of the single‐polarized design, the dual‐polarized design with a profile of 0.09 is investigated and fabricated. According to the measured results, the dual‐polarized prototype achieves a 10‐dB impedance of 60 from 1.6 to 3 GHz.

This research focuses on the design of a super wideband (SWB) antenna and its two-port multiple input multiple output (MIMO) configurations. The antenna is designed to cover the wideband spectrum ranging from 1.42 GHz to 40 GHz, with the additional feature of tri-notch band functionality. The respective band spectrums of 3.5 GHz, 5.8 GHz, and 10.5 GHz, which are worldwide assigned for 5th generation (5G), sub-6-GHz applications, Wireless local area network (WLAN), Industrial Science and Medical (ISM) applications and X-band are notched utilizing different shapes of slots. The SWB is achieved by converting a broadband circular monopole into an asymmetric semicircular monopole offering wideband, which is then modified by implementing the tapered line feed techniques. Furthermore, to reduce the mutual coupling among the MIMO elements, a T-shaped open-ended stub is loaded between them and optimized to achieve a low mutual coupling of ≤-20 dB. Along with that, various MIMO performance parameters are studied and their comparison with the measured results is compared. Lastly, a comparison table is produced to indicate the competence of the suggested work in comparison to the state-of-the-art, which strengthens the provided conclusions.
