A reduced frequency printed quasi-yagi antenna symmetrically loaded with meander open complementary split ring resonator (MOCSRR) elements

In this paper, a modified printed quasi-yagi antenna is presented. In particular, meander open complementary split-ring resonator (MOCSRR) elements are introduced to the design of a printed quasi-yagi antenna to reduce the operating frequency f_o. It is shown that f_o of the antenna can be reduced by 35% by designing the MOCSRR elements to resonate at approximately 2f_o. This lower operating frequency is achieved by taking advantage of the inductive properties of the MOCSRR elements and not increasing the size of the antenna layout. Furthermore, discussion on designing a printed dipole with MOCSRR elements embedded in the layout is presented.
