Abstract :
A simple method of forming the cosecant square beam by using the curved leakywave structure based on the periodic structure is proposed. This method is a low-cost and easy design for beam shaping and is applicable as an antenna for relatively short-range communication systems at millimeter-wave band, including various wireless indoor LANs
