Abstract A novel and small sized implantable antenna has been proposed for scientific industrial & medical (ISM) band applications. The proposed antenna is — shaped antenna and it is a circular patch antenna which has been designed based on the previous research articles and the lower size is achieved by implementing different miniaturization techniques. The radiating structure has a circular shaped patch and it has fillet edges with square shape. The back reflections have been avoided by extending the ground plane over the complete plane. The proposed antenna has been structured by using ROGER 3010 substrate which has the thickness of 1.6 mm and dielectric permittivity of 10.2 in order to achieve the geometries of an antenna with rigidity, the proposed structure has been designed. This antenna structure is operated at 2.45 GHz with the most recommended omni-directional pattern that has been used for transmitting with other in body devices.

Medical gadgets that are linked to telecommunications and antennas are having a positive effect on the medical management at all times. Introducing fabric material-based devices in medical applications has the potential to reduce hospital resources and labor. On body communication modules will be critical in the future to ensure information continuity and decrease information sharing delays. This paper outlines the design and analysis of a miniature antenna using a textile fabric jean as substrate with dimension of 25X22 mm2. Simulation of the proposed antenna is done by using CST Microwave studio and the equivalent circuit of the designed antenna is generated and simulated in AWR software and results are compared. The designed antenna is tested on breast phantom results are analyzed.

Traditional cancer detection imaging techniques suffer high costs, high false negatives, high false positives,and pain. The microwave imaging techniques overcome the limitations, which depend primarily on antenna design. If an antenna is wearable and implantable, the imaging system gives better results with less pain and cost. A wide band fabric antenna that operates at the ultra-wideband frequency with a low specific absorption rate (SAR) on breast phantom is verified. The proposed design has Jeans material as a substrate and the copper patch as a radiating element. The patch is designed in a circular shape with an M-type slot to suppress the spurious modes. The designed antenna model is commonly used for monitoring microwave imaging and has dimensions of 28X30X1.6 mm3. The proposed antenna design covers 2.3-8 GHz frequency with a broadside radiation pattern. The gain over the operating frequency is about 2.3-4.5 dB, and the efficiency is 55 %–79 %. The antenna model was designed and simulated in CST microwave studio. The performance of an antenna is tested on breast cancer to detect the presence of tumor cells in the breast. The antenna analysis on the phantom was done by considering the tumor location and corresponding results are presented. By varying the sizes of the tumor the antenna performance is analysed. The simulated SAR values of the proposed antenna design on breast phantom are under the limits of FCC.

Remote monitoring of the elder people and people with health issues become more crucial in these pandemic days. To face these situations, low-cost wearable devices are developed using advanced communication systems. Design of wearable flexible antenna is important to reduce the dimensions of wearable devices and improper power consumption. A novel UWB antenna is presented in this paper to detect various tumors in the body using microwave imaging. The antenna is designed with jeans fabric of 25X24X1.6 mm3 dimension with slots in the patch. The antenna is simulated and tested on various body phantoms and results are compared.

This paper explores a loaded conductor backed coplanar waveguide (CB-CPW) split ring resonator (SRR) fed U-slot planar antenna used for healthcare monitoring via the wireless scientific industrial medical (ISM) band and medical service band at fifth generation (5G-MSB). The antenna has been designed with bio-tissue layers, muscle layers, skin, and fat. The parameters of the designed antennas, such as miniaturization, increased gain, and enhanced bandwidth, are presented. The proposed prototype results in the total size of 640mm3. Such designed antenna has been operated at (3.4–3.6)GHz — fifth-generation medical service band and at (2.38–2.48)GHz — industrial scientific band and can realize proximately omnidirectional radiation pattern over the operating bands.

In this paper, design of a flexible antenna which is used in the field of biomedical applications. This technology consists of two methods mainly i.e. 1.Magnetron sputtering method, 2.Laser ablation method. Magnetron sputtering method is use to set slight copper coating upon polyimide substrate. Secondly Laser ablation method is mainly used to incise an antenna as of copper coat. The different parameters are simulated and measured practically. The outcomes of the verified results are good and have a satisfactory response. There are many advantages such as price, momentum, elasticity over lithography process frequently used for such applications.

In this paper a novel coplanar waveguide fed antenna with inverted six shaped configuration having wide band attributes, proposed and designed on a FR4 substrate. The dimensions of the designed antenna are 54 mm × 38 mm. Few rounded corners system is used in this design to improve the bandwidth and gain of proposed antenna.
