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,...

Wearable devices are currently of great importance in developing health management and care applications and devices especially for early breast cancer detection (BCD). This is supported by the novel innovations in materials and techniques to construct highly accurate and comfortable biosensors for wearables. In this paper, the proposed flexible sensor is integrated with a Bra to realize a wearable breast cancer detection system. The proposed antenna-based sensor is composed of a CPW monopole antenna with an overall compact size of 24 × 45 mm 2 on flexible PCB Roger substrate with thickness 0.17 mm. The proposed sensors have enough bandwidth from 1.5 to 8 GHz at -6 dB reflection coefficient and conformal structure for biological structures and biocompatibility. The specific absorption rate (SAR) has been calculated and measured for the proposed sensor with a value of 0.75 W/kg at 0 dBm to ensure safety level. For testing, real shaped rubber phantoms from medical school enables the dynamic combination of breast and tumor to create test scenarios for breast cancer detection. 2×2 antenna-based sensors elements are placed around the breast phantom to gather data on scattering parameters for tumor characterization. Several simulation and measurement scenarios are presented to validate detection, optimum number of sensors to be used as well as training data for developed detection algorithms. Artificial intelligence techniques are used among which the CAT-Boost technique for scanning collected data and identifying the undesired tumor component inside the breast.

“…It is found between the millimeter and infrared wave bands on the electromagnetic spectrum [1]. Recently, it has attracted much interest in various fields such as imaging, spectroscopy [2], 6G technology, radar, radio astronomy [3], airport security screening, explosive detection [4], and material analysis [5], because of its larger bandwidth, nonionizing properties, sensitivity to weak interactions, high data rate, high chemical selectivity, and high resolution in wireless communication [6]. The necessity for high gain antennas at THz frequencies is critical to counteract high path loss, and high atmospheric absorption at these frequencies, which will have a negative impact on the wireless link's budget [7].…”

A slotted patch antenna operating at 118 GHz is proposed to address challenges in the terahertz (THz) frequency band for wireless communication systems. The antenna design, utilizing a Rogers RO3003 substrate, which has a dielectric constant of 3 and tan 0.001, strategically incorporates slots to enhance key performance parameters. Copper is employed for the ground and radiating patch, and a microstrip feeding method powers the antenna. High frequency structure simulator (HFSS) software is used for design and simulation, revealing resonance at 0.118 THz with a reflection coefficient of -42.41 dB and an impedance bandwidth of 4.42 GHz (115.84–120.26 GHz). At the operating frequency, the antenna exhibits a gain of 7.36 dB, maximum directivity of 7.38 dB, the voltage standing wave ratio (VSWR) of 1.01, and 99.75% radiation efficiency, all within a compact size of 1.5×1.3×0.1 mm³. The suggested antenna outperforms recent counterparts, making it suitable for applications like security screening and wireless communication systems (5G). Future efforts will target bandwidth expansion, gain enhancement, and further size reduction to enhance overall performance.
