“…The majority of printed-circuit UWB antenna designs are reported in the 3-10 GHz span, with very few designs persisting to cover higher frequencies such as the 3-30 GHz band, with promising applications in medical, air-bone intercept, radar, missile systems, and short-range tracking systems. The Ku band (12)(13)(14)(15)(16)(17)(18) is used for high resolution tracking and tracking the satellite within the bandwidths of approximately 12.87-14.43 GHz and the vehicular radar band (22)(23)(24)(25)(26)(27)(28)(29) [12]. As wireless system tools develop and use higher frequency ranges to provide higher data transfer, a UWB antenna with a frequency range far beyond the FCC-authorized band is required to monitor and enforce various standard compliances, such as EIRP, immunity tests, and interferences.…”

A compact and novel semi-elliptical defected ground structure (SE-DGS) tapered microstrip line fed UWB antenna with band notched characteristics integrated with Ku and K band applications is proposed. The proposed SE-DGS UWB antenna is printed on a compact size of (15×18 mm2) and has an impedance bandwidth of 4.11-29.77 GHz, a fractional bandwidth of 152%, and both the down link of X- and ITU-8 bands are completely notched over a span of 6.86-9.09 GHz using a single C-structured reflector. The proposed antenna has a fluctuating gain of 1.7–4.82 dBi except for the gain at the notched band frequency, which is -12.25 dBi. The proposed antenna has a high radiation efficiency of 96.23%, stable radiation patterns over the UWB range, and a high rejection capability of the notched band, which is noticed from the high value of VSWR of 23.15, making it a potential candidate for UWB, Ku, and K band wireless applications with effectively suppressed downlink of X and ITU-8 bands. The developed antenna design simulates breast cancer tissue detection by comparing S21 outcomes, current densities, and specific absorption rates with and without tumour scenarios. These results suggest that the proposed radiator and system detect breast tumours efficiently.
