摘要

A miniaturized inset-fed on-body meandered bowtie antenna designed forbrain microwave imaging systems is presented in this article. The proposedon-body antenna can contribute to the realization of a wearable and portablebrain microwave imaging system. The size of 18 × 18 mm2 is achieved at a frequencyrange of 0.75 to 4 GHz by the simultaneous use of self-complementarystructures and meandered lines. The frequency band is a trade-off betweenpenetration depth and spatial resolution. The proposed antenna performancewas studied at different positions on the human head voxel model in terms ofseveral parameters such as reflection coefficient, near-field directivity, andfidelity factor. In addition, the antenna bandwidth was surveyed on severalvolunteers using a wearable measurement setup. It has been found that theaverages of measured reflection coefficients in different scenarios are in goodagreement with the corresponding simulation results, and the antenna showsstable performance under different practical situations. The proposed antennatakes advantage of a small footprint and body matching, which make it an eligiblechoice for compact, portable, and wearable head microwave imagingsystems.
