In this research article, a novel technique to design a compact multi-band antenna with asymmetric coplanar strip (ACS) feeding is proposed and discussed for 2.4 GHz Bluetooth/WLAN, 3.6 GHz LTE and 3.4 GHz WiMAX applications. The proposed design is printed on a low cost FR4 substrate with thickness of 1.6 mm and having an overall dimensions of 14.75 × 26 mm2 only. By integrating a rectangular shaped strip and a tilted V-shaped strip to the basic ACS-monopole, desired dual frequency operation is achieved. Simulated and experimental results of the proposed compact monopole antenna are presented and discussed. The experimental results shows that the proposed V-shaped dual-band antenna is having an impedance bandwidth (S11 ≤ −10 dB) of 320 MHz from 2.2 to 2.52 GHz and 900 MHz from 3.3 to 4.2 GHz, respectively. Additionally, the proposed dual-band antenna is also having omnidirectional radiation patterns and constant peak gains with good radiation efficiency.
