摘要: The performance of a circular microstrip patch antenna is improved using new cylindrical electromagnetic bandgap (EBG) substrate. fed by coaxial probe and integrated within substrate, based on the mushroom-like to increase gain. structure combination two periodic structures with different periods. One made metallic rings other grounding vias, which are disposed such as form radially circularly structure. A parametric analysis full-wave method was carried out in order design EBG With proposed concept, an prototype fabricated tested. radiation patterns return loss obtained from measurements show good impedance matching gain enhancement antenna.
