WebTo the best of the authors' knowledge, the proposed EBG exhibits the highest stopband bandwidth (BW) with a bandgap existing between 7.37 and 12.4 GHz (50.9%). Frequency-selective property of the EBG is utilized under plane wave incidence to demonstrate it as PRS superstrate in CRA antenna. WebJul 1, 2016 · The role of superstructure finiteness in improving the peak directivity and the directivity bandwidth (DBW) of electromagnetic band gap (EBG) resonator antennas (ERAs) is studied. Simple one- and two-layer superstructures consisting of unprinted dielectric slabs are used for this purpose. WebNov 8, 2024 · Studying the geometry of electromagnetic band gap (EBG) structures in 1 and 3 dimensions is useful for achieving effective directional radiation, high gain, and side-lobe attenuation of antennae. This paper presents an EBG antenna, whose radiating source is a rectangular notched patch, which can be used for applications around 20 GHz. central junior high school heb isd
