Design of a miniaturized dual-band patch antenna as an array element for microwave breast imaging

In this paper a dual-band miniaturized patch antenna element for a 3-D breast imaging sensor array is designed, fabricated, and validated experimentally. The miniaturized patch antenna exhibits higher gain at the desired frequencies. This will ensure a higher signal-to-noise ratio and imaging sensitivity when immersed in the coupling medium. A high degree of correlation between simulated and measured values is obtained. Due to its miniature size, multi-frequency performance, and efficient radiation characteristics, this antenna is a promising candidate for use in a 3-D microwave tomographic system.
