Research findings from R. Fallahi et al update understanding of electromagnetic research
July 7th, 2008
"This paper presents a novel band-notched elliptical slot antenna for Ultra Wide-Band (UWB) communication, which is printed on a dielectric substrate of RT/duroid 6006 with relative permittivity (er) of 6.0, thickness of 1.27 mm, and fed by an elliptical open ended microstrip line connected to the 50. main line. This antenna is designed to be used in frequency band of 3.1-10.6GHz," researchers in Iran report.
"Band-notched characteristics of antenna to reject the frequency band of 5.15-5.825 GHz, which is limited by IEEE 802.11a, is realized by parasitic inverted-U strip attached to the elliptical slot plane. Effects of varying the parameters of parasitic inverted-U strip...
