“…Table 1 presents the performance comparison of the proposed antenna with the existing fractal and band‐notched antennas. The results show that although the antennas in References 24–26 also use complex CSRR to achieve band notch characteristics, their performance is inferior to the proposed antenna in terms of size and bandwidth. In addition, none of the antennas in References 3, 10–12, 15–18, 23–26 and 35 are flexible, which makes these antennas unable to bend.…”

“…Simultaneously, the research of band‐notched UWB antennas has also been widely concerned. A common method for realizing band notch characteristics is to etch slots of various shapes on the antenna surface 11‐26 . In addition, there are ways, such as using parasitic elements and electromagnetic bandgap structures, to achieve band rejection 27‐35 .…”

A compact flexible fractal ultra‐wideband antenna with band notch characteristic is presented. The antenna is printed on a 12.5 μm flexible polyimide substrate, and an impedance bandwidth of 15.48 GHz (3.6‐19.08 GHz) is achieved along with an overall antenna size of 20.5 × 13.9 mm2. The design of the hexagonal radiator in the fourth iteration effectively enhances the impedance bandwidth of the antenna. By arranging two symmetrical complementary split ring resonators on the ground plane, the band rejection of the X‐band uplink frequency from 7.9 to 8.41 GHz is achieved. The average gain of the antenna can reach 3 dBi in the pass band, while the gain in the notch band is greatly reduced to below 0 dBi. Compared with the existing structure, the antenna has a larger bandwidth and a smaller size. Furthermore, the antenna is tested under bending effects. Test results show that this antenna can be used for integration on flexible electronic devices.

“…Therefore, it is desirable to design UWB antennas with bands notched characteristics. The conventional methods to achieve band-notched function are using parasitic elements [5][6][7][8][9][10], embedding a slit in the feed line [11], or cutting different kinds of slots in radiation patch and ground plane [12][13][14][15][16]. Recently, several UWB antennas with single [5-7, 11, 13-17], dual [12,18], and multiple [8,19] notched band functions have been reported.…”

A new compact ultra-wideband (UWB) antenna with triband-notched characteristics is presented. The structure of the proposed antenna is simple and symmetric. A modified ground is introduced to obtain a wide impedance bandwidth of 2.9–13.4 GHz withS11<-10 dB. By inserting two arc-shaped slots in the radiation patch, two sharp bands of 3.3–3.7 GHz and 5.15–5.35 GHz are notched. The notch band of 7.25–7.75 GHz is achieved by etching a U-shaped slot in the ground plane. The notched bands can be controlled, respectively, while the characteristics of the proposed UWB antenna almost keep completely unchanged at the unnotched frequencies. Equivalent circuit models, surface current distributions, and input impedance are applied to analyze the principle of the proposed UWB antenna. Parametric studies are given. Simulated and measured results show that the proposed antenna has good impedance matching, stable radiation patterns, and constant gain.

Abstract-It is difficult to determine the feed radiation center and F/D of the reflector impulse-radiating antenna (IRA) in frequencydomain, due to its ultra-wideband (UWB) property. This paper presents an efficient approach to design the reflector IRAs, via evaluating the transient radiation patterns (TRPs) of the feed for some given different radiation centers. Only one time-domain simulation for the feed is needed in this method. Comparing with the global optimization algorithms, our method is fast and reliable in the design of the reflector IRAs.
