“…For antenna structure optimization, generally frequency band of the antenna has been chosen as UWB (3.1-10.6 GHz). There are numerous antenna designs that have been presented in [23,[26][27][28][29]. Here considering a resonant frequency of 4 GHz for circular patch with radius as…”

“…The broadened impedance bandwidth of the dual band antenna provides a method to improve the bandwidth. In [18][19][20][21][22][23][24], various types of antennas were designed for different applications, but neither antenna was used for microwave sensors. A crescent shaped slot loaded triple notch microwave antenna sensor was designed and verified for breast tumors at different locations in [25].…”

In this study,a sextuple band-notchedultra-wideband (UWB) antenna sensor with slots in the feedline and parasitics is proposed. This is used for cancer detection in breast and skin phantom. The antenna sensor operates a bandwidth of 2.45 16 GHz- . The dielectric properties of malignant cells are completely distinct from healthy cells, EM waves passing through the cells recognize a malignant. S11 parameters of the antenna are analyzed with the help of a Vector Network Analyzer (VNA) after placing the antenna on the phantoms. Further, the statistical machine learning concept of Principal Component Analysis(PCA) isutilized for more vivid detection of malignant cells. The bands WiMax (2.8-3.4 GHz), radio astronomy (4.75-5.8 GHz), satellite communication (6.7-7.5 GHz, 9.2-10.9 GHz and 12.95-13.55 GHz) and SHF band (15.43-15.63 GHz), create interferences within the UWB spectrum. The interfering bands are removed by slot loading and parasitics. Thus, the sensitivity of the antenna sensor improved.
