A Compact Ultra-Wideband Monopole Antenna for Breast Cancer Detection

In this manuscript, a very compact UWB monopole antenna with large bandwidth, for breast cancer detection is designed and fabricated. The designed antenna has a size 10.2 mmx15.5 mm and operates over a frequency range from 4.23 GHz up to more than 14 GHz. The proposed antenna shows a sufficient variation of transmission response, displays good omnidirectional radiation patterns, gain level reaching to 5.17 dB, radiation efficiency above 85% over the operating band, high fidelity reaching to 0.965 and the maximum variation in a group delay is 0.25 ns. The proposed design achieves the specifications of the element to use in an antenna array for breast cancer detection.
