“…In general there are several techniques for RF transmission lines such as microstrip line, waveguide and coplanar waveguide. However the microstrip antenna [4][5] using a printed board to be patterned by etching is effective in price reduction but it gives significant transmission losses in the millimeter-wave band which in return makes system less efficient. As a solution for this problem directly connect the radiation element and feed line [6] which reduces transmission line losses with high efficiency.…”
