Reconfigurable Metamaterial-Loaded Vivaldi Antennas for Biomedical Microwave Imaging: A Review
By
Progress In Electromagnetics Research C, Vol. 167, 129-140, 2026
Abstract
Vivaldi antennas loaded with metamaterials are currently being utilized in the form of reconfigurable metamaterial-loaded Vivaldi antennas, representing a promising class of antennas in advanced biomedical imaging and sensing applications. The design is an enhancement of the naturally ultra-wideband and high-directivity Vivaldi structure with the miniaturization and field enhancement properties of metamaterial inclusions. Frequency, polarization, and radiation pattern are some of the key features of biomedical diagnostics that can be dynamically reconfigured using tuneable elements like P-I-N diode, varactors, and graphene-based switches. This paper will give a summary of recent findings related to the design, analysis, and uses of reconfigurable metamaterial-loaded Vivaldi antennas in the field of biomedical imaging, especially in the determination of tumours and tissue characterization in non-invasive systems. The discussion notes the development of metamaterial integration methods, reconfigurable mechanisms, choice of substrate materials and their influence on the measure of antenna performance like gain, bandwidth and Specific Absorption rate (SAR). Moreover, fabrication strategies, experimental validation of the use of tissue phantoms, and performance comparison with the traditional antennas are tackled. The future research outlooks have been given at the end of the paper, highlighting compact and low-SAR and optically-controlled antenna architectures of the next-generation biomedical imaging systems.
