Abstract

This paper presents a design of four defective ground surface (DGS) - based patch antennas for early detection of stage 0 brain tumours. The four antennas form a 2 x 2 antenna design and are attached to a dielectric ring suitable for being mounted on the head. The proposed 2 x 2 design is composed of four antenna, two of them having an elliptical DGS, while the other two patches have circular DGS. This system is characterized by comprising compact and highly isolated elements. It operates at a frequency of 2.45 GHz and has a wide bandwidth. The antenna's compact dimensions of 50 x 40 x 1.13 mm3 are achieved by employing a meandering geometry, a defective ground structure, and a high permittivity substrate. It is feasible to obtain a bandwidth wider frequency range of 700 MHz (2.38–2.45) GHz. Furthermore, the defects in the ground construction result in a compact size. The performance of the proposed design is demonstrated through simulated and other parameters results using a brain phantom, including the effects of the tumour and without tumour.
