In this article a novel wide‐band artificial magnetic conductor (AMC) based wideband directional antenna is presented for ultra‐wideband (UWB) applications. The proposed novel cross‐slot AMC (CSAMC) achieves wide ±90° reflection phase bandwidth of 4.07 GHz (44.69%) and is used as a reflector. The overall antenna structure is designed with 4 × 4 CSAMC unit cell array and has very compact size of (0.584λ 0 × 0.584λ 0 ). The proposed structure improves the radiation properties and exhibits 91.5% (3.13‐8.41 GHz) impedance bandwidth (VSWR ≤2). Additionally, it results in significant improvement in gain and front to back ratio. The proposed antenna is fabricated and its measured performance is in good agreement with simulation results.
