A new geometry of wideband circularly polarised antenna with an asymmetric meandered‐shaped monopole is proposed in this communication. The wideband characteristics of the antenna are accomplished by the two asymmetric meandered‐shaped perpendicular arms of monopole and defected ground structure having slanting edge. The proposed prototype offers good performance in terms of impedance bandwidth (close to 102.04% in the frequency range 2.4–7.4 GHz) and the 3 dB axial‐ratio (AR) bandwidth (close to 37.5% in the frequency range 4.9–6.9 GHz). The realised impedance and AR bandwidths cover the WLAN/Wi‐MAX bands and Wi‐Fi band (5.5 GHz).
