MULTIFREQUENCY SELF-DIPLEXED SINGLE PATCH ANTENNAS LOADED WITH SPLIT RING RESONATORS

Capacitor-loaded split ring resonators as tunable metamaterial components

Transmission through split ring resonator SRR structures loaded with capacitors is investigated both experimentally and numerically. Magnetic resonance frequency m is observed to shift to lower frequencies when capacitors are mounted to the various capacitive regions of the SRR structure. The amount of change in m depends strongly on the place where the capacitors are loaded. The magnetic reson...

Enhanced Bandwidth Microstrip Patch Antennas Loaded with High Permittivity Dielectric Resonators

A novel technique fitr the bat dividth enhancement of conventional rectangular microstrip antenna is proposed in this paper. When a high permittivity dielectric resonator of suitable resonant frequency was loaded over the patch. the % bandwidth of the antenna was increased by more than five tunes without much affecting its gain and radiation performance. A much more improved bandwidth was obtai...

Reconfigurable Delay Lines with Split-Ring Resonators

In this paper we proposed anovel multiband delay line which consists of two types of split-ring resonators: the broadiside coupled and the single split-ring resonator. Proposeddelay line exhibits two left-handed bands that can be shifted by twisting the split rings for certain angle or by changing their lengths. This delay line is suitable for design of multiband frequency scanning antennas sin...
