The shape of a popular split-ring defected ground structure (DGS) is modified by etching two concentric split-ring defective pattern which have different size and inverse split direction in the ground plane underneath a microstrip line. The frequency characteristics of proposed DGS unit show an attenuation zero close to the attenuation pole frequency. As a result, better transition sharpness, lower...
This paper presents novel Hilbert fractal shaped complementary single split ring resonator (CSSRR) with a tunable transmission zero realized by negative effective permittivity of it and multi-band property attributes to Hilbert fractal geometry. Transmission characteristics of several CSSRR cells have been assessed by using full-wave electromagnetic simulation. Also miniaturization performance as...
Left handed transmission lines have anti-parallel phase and group velocities, unlike right handed transmission lines with positive phase and group velocities. The propagation characteristics show that backward wave propagation occurs in a Left handed transmission line. A composite Right Left Handed (CRLH) transmission line can be constructed using lumped elements or split rings. Using microstrip coupled...
