A Compact UWB Semi-circular Slotted Patch Antenna for Breast Cancer Sensing: Design and Fabrication
Year: 2025
Type: article
Abstract: This study presents a compact and innovative Ultra-Wideband (UWB) antenna specifically designed for breast cancer detection, leveraging advanced electromagnetic simulation and fabrication methodologies.The proposed antenna incorporates a novel configuration with integrated rectangular and circular slots on a cost-effective FR-4 substrate (𝜀𝑟=4.4),achieving enhanced bandwidth and impedance matching.The design process included detailed simulations conducted using CST Microwave Studio, followed by prototype fabrication and rigorous validation through experimental testing with a Keysight Vector Network Analyzer and referential horn antennas.The experimental results demonstrate excellent agreement with the simulations, confirming the reliability and effectiveness of the antenna.With compact dimensions of 26 × 27 mm², the antenna operates across a wide frequency range of 2.98-10.84GHz (simulated) and 3-10.15GHz (measured), delivering a stable gain of 5.9 dB (simulated) and 5.89 dB (measured).The fractional bandwidth (FBW) is remarkably high, reaching 113.76% (simulated) and 108.75% (measured), underscoring its superior wideband capabilities.Additionally, the antenna's ability to penetrate deep into tissue and detect small tumors highlights its suitability for early-stage breast cancer diagnostics.
