“…Microwave imaging using a microstrip patch antenna is feasible for a patient of all ages because of its easy scanning and less harmful effects, the human body is exposed to the EM radiations with the assistance of a microstrip patch antenna, reflection caused by the inhomogeneous nature of normal and cancerous cells which is received and mapped to get the electrical and magnetic property distribution and geometrical constraints of shape, size, and location of scanned body parts [8]. Previous studies show different antennas have been designed and presented [9][10][11][12][13]. These antennas offer complex geometry which is difficult to design in bulks and the size of the device preferred is to be compact as these antennas are for medical applications.…”

In this article, an ultra-wideband antenna has been presented for medical applications which have a resonant frequency of 10.35GHz and offers a bandwidth of 1400MHz with a return loss of -19db. The presented antenna is low-cost lightweight and can easily be integrated inside the circuit. As this antenna is designed for medical applications its size is compact and is fed utilizing a coaxial feeding technique which is especially plentiful for operative radiotherapy applications. The designed antenna is rectangular and covers an overall size of 24x12mm with a thickness of 1mm. The proposed antenna is designed using CST studio as a simulation tool, the extracted results of important parameters like return loss, surface current, reference impedance, and far-field have achieved remarkable results which are illustrated in the article. which makes it suitable for radiotherapy. A high epsilon valued ε r = 4.8, tan δ = 0.02 substrate GT-008 has been employed as a dielectric material whereas copper is being used for the ground and radiating patches. The performance of the antenna in the X-band is satisfactory which makes it suitable for radiotherapy.
