Interference Enhanced Biomedical Antenna for Combined Heating and Radiometry Application

Medical Antennas for Microwave Radiothermometry of Biological Objects

“…The main disadvantage of such antennas, which prevents their widespread use, is low noise immunity, as they have no screen and interference is induced in an unprotected radiator. Typically, vibrator antennas are made of thin spring wire, though printed vibrator antennas can also be used [9,10]. Unlike waveguide antennas, in which a waveguide segment is located between the radiator and the antenna aperture, the radiator of a printed antenna is printed directly onto the dielectric base.…”

“…Printed antennas are lighter than waveguide antennas, cheaper, have less e ect on skin temperature, and can be designed to be exible. The following types of printed antennas can be distinguished: antennas with a helical radiator [11,12], antennas with an elliptical radiator [2,13], antennas with a rectangular radiator or a radiator of complex shape [14,15], antennas with a slot radiator [3,16], and dipole or vibrator printed antennas [9,10].…”

“…Metallization is deposited on a dielectric substrate made of Rogers 4003 material ( r = 3.55, tan = 0.027) 1.524 mm thick. An antenna was presented in [10] able to operate both in transmit mode (0.9 GHz) and receive mode (3.7 GHz). The antenna is made on a substrate of RO4003C ( r = 3.38; tan = 0.0027) of thickness t = 1.524 mm and has a square shape with a side of 52 mm; silicone rubber (GE Silicone, USA) 2 mm thick is used as a matching layer.…”

Kanser Hastalığı Tespitine Yönelik ISM Bandında Çalışan Mikroşerit Yama Yapılı İki Antenin Elektromanyetik Alan ve Saçılma Parametreleri Verilerinin Değerlendirilmesi ve Kıyaslanması

“…The adaptation of the antenna structures used for various biomedical solutions to the biomedical field has been proven by the studies carried out until today. Microstrip patch antennas are the most preferred structure among these antenna types (Jha et al, 2018;Ketavath, Gopi, & Rani, 2019;Nesasudha & Fairy, 2018;Paracha et al, 2019;Rezaeieh, Antoniades, & Abbosh, 2018;Sabban, 2018;Tofighi & Pardeshi, 2017;Yan, Soh, & Vandenbosch, 2018;Yilmaz, Foster, & Hao, 2019). Designing microstrip antenna structures in a variety of shapes and sizes is easy and relatively inexpensive.…”
