“…Specifically, the inductance is influenced by the length and width of each resonator, whereas the capacitance is governed by the distance between neighboring arms. As discussed in references [28], the interactions between the resonators and the primary radiator function as a filtering mechanism, resulting in the production of a notch band at a given frequency.

“…An in-depth study has been done on wideband antennas with notch band capabilities [14]- [19]. It has recently been shown that a rejected band within a broad operational bandwidth can be generated by appropriately etching several slots of different dimensions on the ground plane [20], the radiating patch [21]- [25], or both [26]- [28]. This band-reject action is achievable when the slot lengths are a multiple of λ n , where λ n represents the wavelength of the antenna at the notch frequency.…”

A multiband microstrip-fed wideband (WB) antenna with filtering notches is described for 3G/4G/5G applications. The proposed antenna comprises three notch bands by etching a modified inverted U-slot, a square ring slot, and an interdigital inductor slot on the patch element and feedline. The antenna resonates at 1.9, 2.3, and 3.5 GHz due to the resonant components' mutual interaction, which eliminates interference at other frequencies. The antenna's measured S 11 are 18.79 dB at 1.9 GHz, −24.8 dB at 2.4 GHz, and −40.6 dB at 3.5 GHz, showing a multiband function with a band-reject level of 0.4 dB. The VSWR is less than two at all resonant frequencies. The effects of altering the notch dimensions on the S 11 and VSWR were explored. The antenna was developed and tested using a Rogers RT/Duroid 5880 substrate. The agreement between measured and simulated results was satisfactory. The S 11 result was validated using the ADS schematic and machine learning techniques. The proposed triband-notched antenna offers encouraging results, with radiation patterns exhibiting omnidirectional characteristics and effective performance within the required frequencies. Current distribution analysis reveals how notches disrupt surface current and lower radiation at specific frequencies. The antenna's gain and efficiency performed satisfactorily in the stated frequency ranges.

“…This model produces a circular polarization inserting the feeding fact to the patch with exiting orthogonal TMO1 and TM10 modes. In [50], the electromagnetic band gap, which is best used in electromagnetics research, is the electromagnetic band gap structure for the ground plane to make it a standard magnetic conductor, which will allow the electric current to radiate capably close to the ground plane. This is often used in modeling a double-band body-worn antenna because it creates a layer on the ground plane to advance the return loss of the antenna so that it gets almost the same resonance frequencies, which will increase the antenna efficiency.…”

The arrival of various mechanism applications to healthcare is gaining more attention with various novel breakthroughs in digitalizing healthcare. The use of technology in improving the delivery of healthcare comprises various applications such as electronic health systems, telemedicine, mobile health, remote patient monitoring, and wearable devices. Wearables and implants are making a significant impact on revolutionizing healthcare globally, and the next generation of advanced technology is providing adequate applications in tackling the challenges in digital healthcare. The advancement of various techniques gives future direction to digitalizing healthcare. Antennas play a key part in digitalizing healthcare because of their characteristics and the adaptation to wireless communication with transmission and reception in different human body parts. Although there are a lot of studies done and published on digital healthcare, telemedicine, wearable, and many more mechanisms that enhance healthcare delivery, however, systematic studies that comprehensively review the applications in healthcare such as wearable antenna framework remain scarce. This paper attempts to close the gap in investigating mechanisms for digital health care, and wearable devices with antenna applications. This comprehensive systematic review covers antenna application in healthcare. Furthermore, it provides a state-of-the-art update on recent developments in healthcare with a focus on design, monitoring devices, diagnostic implants, early detection mechanisms, and control. We also examine wearable analysis and performance, fabrication and experimental approaches, and the major types of wearables. This assists with existing chronic disease management and future epidemics with provided tools. This finding will give a blueprint of how zero spread of future epidemics will be achieved by implementing the bio-electromagnetic application in the healthcare sector.

The design and analysis of a compact coplanar waveguide (CPW) fed wearable slot antenna with four notched bands for ultra-wideband (UWB) applications are presented in this paper. The antenna is printed on a 0.1-millimeter-thick liquid crystal polymer (LCP) substrate, providing flexibility for wearable applications. Split concentric rings (SCRs) engraved on the radiating patch and Lshaped branches loaded on the ground plane provide the antenna's notched features. The impedance bandwidth of the measured antenna ranges from 2.46 GHz to 12.52 GHz, with a fractional bandwidth (FBW) of 134.1%, and it exhibits notched bands covering specific frequency ranges, ranging from 2.84 GHz to 3.93 GHz for WiMAX applications, 4.84 GHz to 5.41 GHz for WLAN downlink, 5.66 GHz to 6.26 GHz for WLAN uplink, and 6.94 GHz to 7.79 GHz for X-band satellite communication. Furthermore, the gain of the proposed antenna varies between 1.5 and 6 dBi, excluding the notched band. The antenna is tested, and the flexibility performance is good. In a word, the fabricated antenna shows promising prospects for wearable applications.
