摘要：
A novel compact (20×22 mm2) triple band eliminated monopole antenna for ultra-wideband (UWB) applications is presented. A novel radiating patch with reduced ground plane is utilized for achieving a −10 dB impedance bandwidth of 3.28–13.28 GHz. An upper inverted U-shaped slot is introduced into the radiating patch to notch C-band (3.68–4.19 GHz), and a lower inverted U-structured slot is utilized to eliminate WLAN band (5.18–5.82 GHz) interference. The interference due to down link of X-band (7.27–7.87 GHz) is rejected by via hole connected between patch and rectangular strip printed above the defected ground structure. The proposed antenna has nearly stable radiation patterns, and realized gain over UWB frequency range makes it suitable for recent portable wireless communication applications. © 2020, Electromagnetics Academy.
