Good Agreement

Stable radiation pattern, high gain, and miniaturization are necessary for the ultra-wideband antennas in the 2G/3G/4G/5G base station applications. Here, an ultrawideband and miniaturized spoof plasmonic antipodal Vivaldi antenna (AVA) is proposed, which is composed of the AVA and the loaded periodic grooves. The designed operating frequency band is from 1.8 GHz to 6 GHz, and the average gain is 7.24 dBi. Furthermore, the measured results show that the radiation patterns of the plasmonic AVA are stable. The measured results are in good agreement with the simulation results.

In this paper, the design, simulation, and fabrication of a novel printed rectangular slot antenna with a band-notched function suitable for 2.4 GHz wireless local area network (WLAN) and ultra-wideband (UWB) applications is presented and investigated. Two pairs of slits are introduced into the ground plane to realize band-notched function, by tuning the position, length, and width of which a suitable rejected frequency band can be obtained. To improve the impedance matching, a rectangular cut is also made in the ground plane so that the antenna can cover 2–12 GHz frequency range. According to the measured results, the proposed antenna has a large bandwidth totally satisfying the requirement of 2.4 GHz WLAN and UWB systems, while providing the required band-notch function from 5.1 to 5.9 GHz. The study of transfer function and time-domain characteristics also indicates the band-notched function of the antenna. The radiation patterns display nearly omni-directional performance and the antenna gain is stable except in the rejected frequency band (5.1–5.9 GHz). Moreover, group delays are within 1.5 ns except for the notch band. These features make it a promising candidate for UWB wireless applications. Details of this antenna are described, and the experimental results of the constructed prototype are given.

Antenna Structure

In this article, a dual-band notched ultra-wideband (UWB) dielectric resonator antenna is proposed. The antenna structure consists of Crescent Moon Dielectric Resonator (CMDR) fed by a stepped microstrip monopole printed antenna, partial ground plane, and an I-shaped stub. The Crescent Moon dielectric resonator is placed on the microstrip monopole printed antenna to achieve wide impedance bandwidth, and the I-shaped stub is utilized to improve impedance bandwidth for the WiMAX band. A comprehensive parametric study is carried out using HFSS software to achieve the optimum antenna performance and optimize the bandwidth of the proposed antenna. The entire band is useful with two filtered bands at 5.5 GHz and 6.8 GHz by the creation of notches. The band’s rejection, WLAN band (5.2–5.7 GHz), and the downlink frequency band of ITU 7 GHz-band for satellite communication (6.5–7.3 GHz) is realized by inserting G-shaped and C-shaped slots in the ground. The simulation results demonstrate that the proposed CMDR antenna achieves satisfactory UWB performance, with an impedance bandwidth of around 88.7%, covers the frequency band of 3.2 - 8.3 GHz, excluding a rejection band for the WLAN and ITU 7 GHz band. The CMDR is simulated using HFSS and CST high-frequency simulators.
