摘要：

A novel design of a dumbbell shape quad elliptical slotted (DSQES) antenna for directive ultra-wideband (UWB) integrated with WCDMA, WLAN, and mid-band of 5G applications is presented. Initially, a circular patch is designed by inserting four elliptical slots in radiator with a rectangular slotted ground plane. To realize ultra-wide impedance bandwidth, three symmetrical stepped rectangular slots are inserted in ground below a stepped-quarter-wave-transformer feed line. The proposed antenna achieves fractional bandwidth (FBW) of 104% (S11 ◦ –20◦ in 5.4–17.3 GHz UWB, respectively. The optimized dimension of proposed antenna is 30 × 30 mm2 which is simulated on Computer Simulation Technology (CST) electromagnetic simulator using an FR-4 substrate of thickness 1.6 mm and dielectric constant 4.3. The simulated structure is computed by ADS simulator, and simulated results are validated with measured ones. © 2024, Electromagnetics Academy. All rights reserved.
