A wideband microstrip‐line‐fed hexagonal wide‐slot antenna is proposed and experimentally investigated. The hexagonal slot excited by a simple 50 Ω microstrip line with a rotation angle of 0° having 470 MHz bandwidth is considered as a reference antenna. The proposed hexagonal slot is rotated by 30° and excited by a 50 Ω line loaded by a hexagonal tuning stub. The experimental results exhibit matching impedance below a 2:1 VSWR bandwidth of 5165 MHz (2.117–7.282 GHz) covering all the WiMAX and wireless local area network band applications, which is about 110% w.r.t. a centre frequency of 4699.5 MHz. The impedance, radiation and gain characteristics of the proposed configuration are studied and the results are exhibited accordingly.
