Microwave sensing and imaging technologies are gaining interest and reliability in diagnosing and monitoring pathologies in which there is a change in the dielectric properties of tissues, such as stroke, Alzheimer’s, and brain tumors in the head. For this reason, there is a need for broadband sensors/antennas working in microwave frequencies to make non-invasive devices able to detect and monitor these pathologies. In this work, we present a flexible and compact antenna optimized for microwave head imaging and sensing, operating in a frequency range of 1.3 GHz−4.7 GHz. It consists of a printed z-shaped monopole with a frontal block of flexible material with custom permittivity and conductivity that improves field penetration into the tissues and reduces the mismatch between the head and the surrounding media.

Abstract

Microwave sensing and imaging technologies are gaining interest and reliability in diagnosing and monitoring pathologies in which there is a change in the dielectric properties of tissues, such as stroke, Alzheimer’s, and brain tumors in the head. For this reason, there is a need for broadband sensors/antennas working in microwave frequencies to make non-invasive devices able to detect and monitor these pathologies. In this work, we present a flexible and compact antenna optimized for microwave head imaging and sensing, operating in a frequency range of 1.3 GHz−4.7 GHz. It consists of a printed z-shaped monopole with a frontal block of flexible material with custom permittivity and conductivity that improves field penetration into the tissues and reduces the mismatch between the head and the surrounding media.
