<p>This paper presents the generation of various OAM modes using single octagonal shape patch antenna. The proposed OAM antenna is compact in size and can generate multiple OAM modes using proper feeding techniques. The proposed OAM antenna is designed and simulated for resonating frequency of 5.2 GHz, WLAN band and it can generate OAM beam with topology charge l = 0, ±1, ±2 and ±3. Beam of topology charge ±3 is also generated but with little distortion.</p>
