Several research articles are available in the literature regarding the design of antennas, but hardly (to the best of authors' knowledge) few papers covered the antennas that are designed for the detection, diagnostics, and monitoring of various diseases. There is a need for a research article in which the design and performance of such significant antennas should be compared and highlighted based on various available design techniques to enhance performance parameters that include efficiency, bandwidth, size and appropriate bio-compatible material used to transmit data from the human body efficiently. Antennas are essential in biomedical applications for wireless communication, miniaturization, integration, implantable devices, diagnostic imaging, biotelemetry, and biosensing. They enable efficient and reliable wireless connectivity, facilitating remote monitoring, improving patient care, and advancing medical research. Designing biomedical antennas presents several challenges, including miniaturization and integration into compact devices, ensuring biocompatibility with the human body, conforming to biological structures, mitigating electromagnetic interference (EMI), accounting for signal attenuation and propagation in the body, optimizing power efficiency, and ensuring compliance with regulatory standards. Overcoming these challenges requires expertise in antenna design, biocompatibility, electromagnetic modelling, and collaboration between disciplines. Therefore, a detailed review is required so that any scholar who wishes to excel in this field may read this review to understand future directions better and work already done for the design of biomedical antennas. This review comprises a comparison of several significant biomedical antenna design techniques used for the detection, diagnosis and monitoring of various diseases, which can be helpful for the medical community for the detection of various diseases, including skin cancer, breast cancer, lungs cancer, endoscopy, brain tumor and glucose level detection. The various features of biomedical antennas are thoroughly investigated to provide performance metrics of the antennas designed to diagnose various diseases. The advantage of this study is the understanding of different types of antennas for various diseases. This study also allows realizing appropriate bio-compatible materials and flexible materials for biomedical antenna design, the effect of Specific Absorption Rate (SAR) on human/animal body and finally, the tables provide the antenna performance in terms of gain, bandwidth, and directivity with respect to antenna size and type of substrate material used for each disease. These biomedical antennas have several applications for diagnosis, early-stage cancer detection and, in some cases providing enough energy to cure the cancer cells in the human/animal body. Moreover, the implementation of Machine learning algorithms for the early detection of tumor for the above-mentioned diseases is also discussed. INDEX TERMSbiomedical antenna, breast cancer,...

“…The evaluation of the antenna from the previous works with the proposed antenna is presented in Table 6. Considering the antenna with compact size, only antennae from [13][14][15] and [16][17][18] are being considered for the evaluation. One of the main requirements for head imaging is the antenna must operate within the range of 1 GHz to 4 GHz; thus, the antennas that are capable of operating within the ranges are from [13], [17] and [18].…”

“…However, the problem with this antenna lies in its omnidirectional pattern radiation instead of a unidirectional pattern, which may lead to a waste of signal wave. In a study conducted by [15], a circular modified ultrawideband (UWB) antenna microstrip is proposed for the detection of brain cancer. The proposed antenna is compact and capable of producing high gains, desired radiation patterns and a remarkably wide bandwidth of frequency.…”

The development of antipodal Vivaldi antenna with a fractal slot is presented in this paper due to its promising application as an element of possible multisensory systems of head stroke imaging. The fractal slot is applied to improve the directivity, bandwidth and gain of the antenna. Hence, this research mainly aims to create and optimise a compact Vivaldi antenna through the fractal slot for the detection of stroke in the human head. The antenna is designed with an overall dimension of 65 × 65 × 1.6 mm 3 using Roger RO4350B as a substrate through the CST Studio Suite 2019 software. The proposed antenna will also be compared with an antipodal Vivaldi antenna without the fractal slot to observe differences in the result. The proposed antenna can produce a wide bandwidth of 1.44 GHz ranging from 2.35 GHz to 3.79 GHz at the maximum gain of 7.35 dBi. Furthermore, the prototype antenna has a directivity characteristic, which produces the unidirectional radiation necessary for microwave imaging procedures. The proposed antenna is also evaluated with the CST studio head model, thus providing satisfactory penetration results through the head tissue. A value of 0.0013 W/kg per 10 g is achieved for the maximum SAR. Thus, the proposed antenna met most of the requirements for the imaging process, which will affect its effectiveness during scanning of head stroke.

“…In [11,12], planar monopole antennas utilizing an FR4 substrate were suggested. However, PCB antennas with common substrates like FR4 or Rogers often have a thick profile, which may not be suitable for compact designs [13,14]. To address the issue of antenna miniaturization, one solution involves utilizing thin film technology.…”

This paper presents the design of a miniaturized polyimide-based antenna for ultra-wideband (UWB) communication. Miniaturization is achieved through the utilization of adhesive material with a high dielectric constant (high-Dk). The goal of this work is to investigate the impact of such material on the antenna performance and to optimize its design for UWB operation. The manufacturing of the antenna using the proposed structure is developed, and the prototype of an antenna for the UWB high band (6–9 GHz) is measured and analyzed. By leveraging the high Dk of the adhesive material, the simulation and measurement results show that the proposed antenna with a high-Dk adhesive film can achieve compact dimensions with good performance in terms of the gain and time domain characteristics. The results of this study show the potential of exhibiting a reduction in the size of the antenna and will contribute to the advancement of miniaturized UWB antenna technology.
