Wideband and dual-band antennas with band-notched using electromagnetic band-gap structure

نویسندگان

چکیده

This paper presents a single-element microstrip spade-shaped patch antennas with partial ground plane, integrated an electromagnetic band-gap (EBG) structure, and fed feedline to achieve wideband, dual-band band-notched characteristic. Two similar mushroom-like EBG structures built into the wideband antenna were used suppress specific band, resulting in dual-band. The wide-band achieved broad bandwidth of 9GHz from 5-14GHz, maximum gain 6.8dBi. Based on simulation measured results, offers 89% fractional for voltage standing wave ratio less than 2 (VSWR < 2). provides band-notch 3GHz 8-11GHz, leaving bandwidths 2GHz 1.5GHz centred at 7GHz 11GHz, respectively. Surface current distribution parametric studies conducted better understand behaviour influence parameters. results validated through experimental measurement, both agreed well. could be 5G wireless communication filtering.

Dual-Band Electromagnetic Band Gap Structure for Noise Isolation in Mixed Signal SiP

A compact dual-band electromagnetic band-gap (EBG) structure is proposed. It is shown through numerical simulation using 3D electromagnetic finite element modelling that by adding a slit to the classical mushroom shape an extra resonance is introduced and thus dual-band EBG structures can be built by cascading these new elements. It is also demonstrated that this novel approach can be used to i...

Electromagnetic Band Gap Materials Simplify the Structure of Dual Polarized Satellite Communications Antennas

The dual polarized reflector antenna used for satellite communications consists of two reflectors; one reflector is solid, the other consists of metal grid. The structure is complicated and the bandwidth is narrow. This antenna structure can be simplified by removing the metal grid and using the solid reflector together with a thin electromagnetic band gap material pasted to the surface of the ...
