“…[8][9][10]. Usually, one slot/parasitic element is sufficient to generate a single-notch [11]. However, to generate dual-notches requires either two different slots or two parasitic elements with different lengths.…”

An ultra-wideband (UWB) antenna with dual band notched characteristics verified by characteristic mode analysis (CMA) is presented. The intended UWB radiator is etched on a Rogers RT5880 substrate with a size of 29 × 35 × 0.764 mm 3 , operating over a spectrum of 2.66-14.86 GHz with a fractional bandwidth (FBW) of 139%. Dual notched bands at WiMAX (3.01-3.63 GHz) and WLAN (4.48-5.85 GHz) are achieved by embedding L-shaped stubs in the notched rectangular patch. In addition, the two notched bands of the reported antenna are verified by using characteristic mode analysis (CMA) in terms of modal significance (MS) and characteristic angle (CA). The reported antenna's simulated and tested results are well matched to obtain S 11 , VSWR, stable radiation patterns, a stable peak gain of 2.65 to 3.6 dBi, and the maximum radiation efficiency of 97.86% in frequency domain, which make the intended radiator suitable for portable UWB applications.

“…As a corollary, ultra wideband (UWB) wireless signals utilizing frequencies ranging between 3.1-10.6 GHz, which were approved by the FCC in 2002 [1], are being developed. For a long time, wideband antennas for telecommunications and radar systems have been investigated [2], [3]. Antenna design for a wideband hand-held device is particularly difficult because of the trade-offs that must be made between portability, economy, and convenience of use.…”

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.

“…Many UWB element layouts have already been proposed in the context of UWB communications. The majority of these antennas are planar monopoles with rectangular, circular, and elliptical designs [11][12][13]. The current designs of these antennas do not make them easy to use for microwave imaging.…”
