Compact Dual-Layered Wideband Wearable Monopole Antenna with Circular Parasitic Element for Breast Cancer Detection

A dual-layered wideband antenna with coplanar waveguide (CPW)-base and circular parasitic element technique was proposed. In comparison to past research problems, which largely produced omnidirectional and hard antennas, it should be flexible, unidirectional, wideband, low weight, and compact. The wearable antenna consists of three stages, whereby Antenna $A$ is designed by a basic rectangular antenna with CPW. Design $B$ is the next stage of antenna design development with the patch size modified. Antenna $C$ is the next development stage with extra circular parasitic element and felt substrate. The bandwidth of 4.11 GHz (79.8 %) of the proposed antenna, which ranges from 2.89 GHz to 7.0 GHz, combines a number of wideband resonant frequencies, including those at 3.07 GHz, 3.90 GHz, 4.35 GHz, 5.15 GHz, and 6.32 GHz. There is also a 40 MHz-wide narrowband that functions between 1.15 GHz and 1.19 GHz and with resonance at 1.17 GHz. This proposed antenna is designed to develop a multifunction application future work system, particularly for breast cancer detection.
