“…To solve this problem, various techniques have been introduced to improve the radiation properties of the antenna without affecting the impedance bandwidth and return loss. An example for these methods is replacing electrically conducting reflectors by partially reflective surfaces (PRS) [5], frequency selective surfaces (FSS) [6][7][8], meta-surface [9,10], and artificial magnetic conductor (AMC) [11][12][13][14].…”

In this paper, a new artificial magnetic conductor (AMC) structure is proposed to enhance the performance of an ultra-wideband (UWB) antenna for wireless communication networks. A fractal configuration is used to introduce the UWB performance of the proposed antenna. The antenna is composed of a modified rectangular patch antenna with a tapered section fed by a coplanar waveguide (CPW) with a total size of 24 × 20 × 1.5 mm 3 . The antenna is backed by an AMC. The proposed AMC unit consists of a square patch surrounded by four slotted square rings. This unit cell exhibits an in-phase reflection from 6.3 GHz to 10 GHz. The obtained bandwidth of the antenna with AMC is 110% from 3.2 GHz to 11 GHz which covers the entire UWB range. The peak gain of 7.2 dB is accomplished with a compact size of 40 × 40 × 6.5 mm 3 , 0.95 × 0.95 × 0.15λ o at 7.1 GHz. The proposed UWB antenna-AMC is fabricated and measured for verification.
