“…As it can be observed, the fidelity factor in both planes is more than 0.82, making the antenna suitable for most practical UWB applications. It is worth mentioning that the proposed antenna has an overall size of 28 × 28 mm 2 , which is less than the size of the presented antennas in [25] and [26] with dimensions of 50×50 mm 2 and 48×42 mm 2 , respectively. The impedance bandwidths of the antennas in [25] and [26] are 118.8% (2.8-11 GHz) and 125% (3-13 GHz), respectively, whereas the impedance bandwidth of the antenna in this design is 129% (2.7-12.55 GHz).…”

“…Also, the fidelity factor is calculated in both E-and H-planes by using CST Microwave Studio. Compared with the recent designs presented in [25] and [26], the designed antenna has a smaller size and wider bandwidth. The measured outcomes show that the antenna is a competent option for the use in UWB communication systems.…”

“…Its impedance bandwidth ranges from 3.7 to 10.1 GHz. Two UWB CPW-fed printed antennas with dimensions of 50×50 mm 2 and 48×42 mm 2 and impedance bandwidths of 118.8% and 125% are reported in [25] and [26], respectively. Recently, a bandwidth-enhancement method of using a new radiator with a hybrid square-circular configuration and a rectangular open slotted ground plane with a pair of symmetrical I-shaped tuning stubs was introduced to implement a CPW-fed planar monolayer UWB antenna with a size of 44 × 32 × 1.6 mm 3 [27].…”

Abstract-A compact ultra-wideband (UWB) antenna with simple structure is presented. To achieve UWB performance with a compact size, two open ended rounded inverted L-shaped slots are etched on the square ground plane. Moreover, further bandwidth enhancement is obtained by cutting a bevel on the asymmetrical radiating patch. The antenna is fed by a 50 Ω microstrip line and has a small size of 28 × 28 × 1.6 mm 3 . The simulation time-and frequency-domain results obtained from HFSS simulator package are verified by experimental measurements. Both simulated and measured results show that the antenna can provide a wide impedance bandwidth of more than 129% from 2.7 to 12.55 GHz with −10-dB reflection coefficient. Besides, it is shown that by introducing several antenna designs, the impedance bandwidth can be enhanced from 58% to 129%. The effects of the key design parameters on the antenna impedance bandwidth are also investigated and discussed. Measured results for the reflection coefficient, far-field radiation patterns, radiation efficiency, gain, and group delay of the designed antenna over the UWB spectrum are presented and discussed. Measured data show good concordance with the numerical results. Also, the fidelity factor is calculated in both E-and H-plane by using CST Microwave Studio. The obtained results in both time-and frequency-domain indicate that the antenna is a good option for UWB applications.

Abstract-A low-profile planar monolayer antenna for ultra-wideband (UWB) operation is presented. To achieve a UWB performance along with a compact size, a hybrid square-circular radiator and a rectangular open slotted ground plane with two symmetrical I-shaped tuning stubs are proposed. The antenna is fed by a coplanar waveguide line and has a small size of 44 × 32 × 1.6 mm 3 . The prototype of the proposed antenna was fabricated and tested in an anechoic chamber. The simulated and measured results show good agreement over the entire ultra-wide bandwidth. The measured results indicate that the proposed antenna can provide a wide impedance bandwidth of more than 154% from 1.7 to 13.3 GHz with −10-dB reflection coefficient. In addition, it is demonstrated that by introducing several antenna designs, the impedance bandwidth can be improved from 43% to 154%. Besides several mechanical advantages, such as compact in size, easy fabrication, and monolayer configuration without any back ground plane, the proposed antenna also shows a good performance in its radiation characteristics and time-domain behaviors. The measured results in both frequency and time domains prove that the proposed antenna can be used in a wide range of UWB applications.

Ultra‐wideband technology has experienced a rapid growth over the last decade for its contribution in different sectors of human society. Printed antennas are considered as preferred platform for implementing this technology because of its alluring characteristics like light weight, low cost, ease of fabrication, integration capability with other systems, etc. Antennas developed for ultra‐wideband applications are desired to have notch characteristics for avoiding interference with other existing radio communication systems. The techniques related to design and developments of printed band‐notched antennas are continuously upgraded for improving the antenna performance. In this article, a comprehensive review has been carried out on ultra‐wideband antennas with band notch characteristics proposed in around last decade. The band notched UWB antennas available in the literature have broadly been classified into five different categories based on their notch characteristics like single band‐notch, dual band‐notch, triple band‐notch, quad/multiple band‐notch, and reconfigurable/tunable band‐notch, respectively. This review exercise may be helpful for beginners working on ultra‐wideband band‐notched antennas and also such a review process is not available in the open literature to the best of author's knowledge.
