“…The ultra-wideband MIMO concepts used in the identification of tumours are briefly discussed in [46]. Therefore, the construction of a circular, fractal-shaped transmitter with a size of 60 × 100 mm 2 and an ultra-wide BW of 3.1-12.0 GHz is detailed in this paper [47]. It also includes a human interface MIMO UWB antenna operated with a BW of 3.1-11.2 GHz and dimensions of 36 × 22 × 1.6 mm 3 [48].…”

This paper represents a miniaturized, dual-polarized, multiple input–multiple output (MIMO) wearable antenna. A vertically polarized, leaf-shaped antenna and a horizontally polarized, tree-shaped antenna are designed, and the performance of each antenna is investigated. After designing the MIMO antenna, it is loaded with stubs, parasitic spiral, and shorting pins to reduce the coupling effects and remove the unwanted resonances. Afterward, the two-port MIMO cells are spaced by 2 mm and rotated by 90° to create three more cells. The antennas are designed using two layers of denim and felt substrates with dielectric constants of 1.2 and 1.8, and thicknesses of 0.5 mm and 0.9 mm, respectively, along with the ShieldIt™ conductive textile. The antenna covers a bandwidth of 4.8–30 GHz when the specific absorption rate (SAR) meets the 1 g and 10 g standards. Isolation greater than 18 dB was obtained and mutual coupling was reduced after integrating shorting pins and spiral parasitic loadings. A maximum radiation efficiency and directive gain of 96% and 5.72 dBi were obtained, respectively, with the relatively small size of 11 × 11 × 1.4 mm3 for the single element and final dimensions of 24 × 24 × 1.4 mm3 for the full assembly. The antenna’s performance was examined for both on-body (breast) and free space conditions using near-field microwave imaging. The achieved results such as high fidelity, low SAR, and accuracy in localization of the tumour indicate that the MIMO antenna is a decent candidate for breast cancer imaging.

Breast cancer, a common and deadly cancer for woman, is gradually increasing each year. Magnetic resonance imaging, mammography, tomography, ultrasound, and biopsy are some of the medical technologies that can be used to identify breast cancer. However, none of them are as simple and effective as a microwave imaging (MI) technique. MI is a non-ionizing, non-invasive, tumor-sensitive, low-cost approach. The performance of MI is primarily determined by the antenna employed in the system. Here, we propose a new partial ground plane and slots-based miniature patch antenna designed for breast tumor detection within the FCC's authorized range (3.1 GHz – 10.6 GHz). The dimension of this antenna is 30 × 20 mm2. High-frequency structure simulator (HFSS) software is used to design a breast phantom with and without a tumor, and the antenna is separately simulated on both the tumored and tumor-free breast phantoms. The presence of a tumor within the breast is clearly depicted by the changes in return loss, VSWR, current density, electric field, and magnetic field strengths. The findings demonstrate that the proposed antenna is a suitable sensor which can detect a very tiny breast tumor (2 mm) due to its compact size and broad bandwidth.
