“…As can be seen, the proposed antenna does not achieves miniaturization, because it is based on the Sierpinski technique, which is used to produce a multiband effect. However, the proposed antenna has a superior bandwidth (175.72%) than the other works presented in Table 2 [1,[27][28][29][30].…”

In this article, a novel structure of a planar monopole antenna for Super Wide-band applications is proposed. The structure is based on the complementary Sierpinski triangle surrounded by two semi-circular sectors. The ground plane of the antenna has been modified including some slots to improve the operating bandwidth and coupling. The simulated and experimental results show that the antenna achieves a ratio impedance bandwidth >15:1 (from 1.68 to 26 GHz) for S 11 210dB.

“…To date, numerous broadband and planar printed monopole microwave antennas have been developed for breast cancer detection due to their simple structure, broadband property, compact size, and ease-to-fabricate [ 84 , 85 , 86 ]. Recently, few flexible antennas were proposed to apply in the microwave sensor array for breast tumor detection [ 87 , 88 , 89 , 90 ].…”

Breast cancer is the leading cause of death among females, early diagnostic methods with suitable treatments improve the 5-year survival rates significantly. Microwave breast imaging has been reported as the most potential to become the alternative or additional tool to the current gold standard X-ray mammography for detecting breast cancer. The microwave breast image quality is affected by the microwave sensor, sensor array, the number of sensors in the array and the size of the sensor. In fact, microwave sensor array and sensor play an important role in the microwave breast imaging system. Numerous microwave biosensors have been developed for biomedical applications, with particular focus on breast tumor detection. Compared to the conventional medical imaging and biosensor techniques, these microwave sensors not only enable better cancer detection and improve the image resolution, but also provide attractive features such as label-free detection. This paper aims to provide an overview of recent important achievements in microwave sensors for biomedical imaging applications, with particular focus on breast cancer detection. The electric properties of biological tissues at microwave spectrum, microwave imaging approaches, microwave biosensors, current challenges and future works are also discussed in the manuscript.

“…Shunt‐fed dipole 8 using higher‐order modes also achieves multiband operation. Ultrawideband antenna is another solution for covering multiband 9–12 . Printed monopole antennas in the shape of rectangular, 9 triangular, 10 and circular 11 with a ground on the back of the substrate are capable of covering a wide bandwidth.…”

In this paper, a low‐cost compact omnidirectional antenna is presented. By directly folding a rectangular‐shaped copper plate into an open‐loop structure, two resonant modes are generated for tri‐band operation. The shape of the rectangular has the highest yield in stamping processes for massive production. Two shorting stubs are loaded symmetrically to reduce the height of the antenna while keeping omnidirectional radiation. Moreover, a compact ground is utilized, making it more suitable to be installed on the PCB of routers. To validate the design, a prototype has been fabricated and measured. The measured −10 dB impedance bandwidths are 2.38–2.52 GHz (4.90%) and 4.16–7.40 GHz (56.06%). The gain variation in the whole operating band is less than 2.5 dB. The antenna profile and ground size are miniaturized to 0.14λ0 and 0.52λ0, respectively. The proposed antenna is a good candidate for Wi‐Fi 6 and 6E routers, with the merits of low cost, compact size, and ease of massive production.
