ABSTRACT
In this thesis, we will discuss two topics about antennas. First, the slow wave effects will be used to design the compact antenna. The elementary structure of the compact antenna is that shorting and feeding positions are located respectively on both sides of the designed antenna. The slow wave effect will be introduced by etching applicable geometric figures on radiator of the antenna and the slow wave effect can be changed by adjusting the etching posit
