- The design was published by Dragoslav
most of his work is in Serbian, but we have corresponded in English. He and I differ a little about he dimensions of his AMOS antenna. When I build the antenna as he describes, it usually has best VSWR below the Wifi band, so I shortened it a little.
This antenna is suitable for use in Computer Radio LANs conforming to the IEEE 802.11b/g standard – better known as Wifi. It can be used on an Access Point (or wireless Router) or Wifi client with equal benefits. Principle The antenna is a centre-fed broadside array antenna, based on the Franklin Antenna as published in Rothammels Antennebuch (shown on the right) This is the complete design in Serbian as published by YU1AW: Amos.zip (3,7MB),
This is my version of his design. Overall, the dimensions are a little shorter:
