Compact Multiband Printed IFA on Electromagnetic Band-Gap Structures Ground Plane for Wireless Applications

الملخص EN

The fourth mobile generation requires of multistandard operating handsets of small physical size as well as has an increasing demand for higher data rates.

Compact multiband printed inverted-F antennas (IFAs) for available wireless communications are proposed in this paper.

A new design of a printed IFA based on a uniplanar compact EBG concept is proposed.

An L-loaded printed IFA shaped over an artificial ground plane is designed as the main antenna to cover the GSM, LTE, UMTS, bluetooth, and WLAN.

The multi-band is created by means of an electromagnetic band-gap (EBG) structure that is used as a ground plane.

Different shapes of uniplanar EBG as ring, split ring resonator, and a spiral rather than mushroom-like structure are investigated.

The proposed antenna is built on the uniplanar EBG ground plane with a size of 35×45 mm2, which is suitable for most of the mobile devices.
