A single layer single probe‐fed wideband microstrip antenna is presented and investigated. By cutting a U‐slot in the rectangular patch, and by incorporating two identical U‐shaped parasitic patches around both the radiating edges and the nonradiating edges of the rectangular patch, three resonant frequencies are excited to form the wideband performance. Details of the antenna design is presented...
A compact rectangular open slot antenna is investigated in view of ultra-wideband (UWB) applications. A stepped strip is used to achieve wide bandwidth. The proposed antenna is fabricated and its performances are measured. The measured results show that the antenna of 26.5 mm × 12 mm dimensions sufficiently covers the band of UWB from 3.06 GHz to 10.6 GHz. The antenna gain across the UWB band is also...
In this paper, a compact micro strip-line-fed open slot antenna with a frequency-notch function is investigated for ultra-wideband (UWB) applications. To achieve wide bandwidth and partial band cutoff, a stepped strip and two pairs of slits on both sides of the slot are used respectively. A prototype of the proposed antenna is fabricated and its performances are measured. The measured results show...
The user's hand effects on the EMC GSM/DCS antenna embedded in the mobile phone have been presented. Although the EMC antenna is easy to be integrated into a mobile phone with nearby electronic components or conducting elements, the performance of the antenna is still greatly affected when a user's hand holds the mobile phone. Even when the phone was hand-held at the bottom, large efficiency drops...
