Zeroth Order Resonator Antenna (ZORA) using CRLH Transmission Lines
A compact Zeroth Order Resonator Antenna (ZORA) is implemented as a part of course work for Radio Frequency Integrated Circuits and Systems (E8-242). This work is based on [1] . Due to the unique properties of Compact Right/Left Handed (CRLH) transmission lines, the size of the antenna is independent of the frequency of operation. This compact structure is made of two unit cells each comprising...
متن کاملNegative refraction through an impedance- matched left-handed metamaterial slab
We report the transmission and reflection characteristics of a two-dimensional (2D) left-handed metamaterial (LHM). A well-defined left-handed (LH) transmission band with a peak value of −9.9 dB is obtained at frequencies where both effective permittivity and permeability are negative. A very sharp dip −38 dB at the reflection spectrum due to impedance matching at the surface of a 2D LHM is obs...
متن کاملOblique response of a split-ring-resonator-based left-handed metamaterial slab.
We experimentally studied the transmission response of a one-dimensional rectangle-prism-shaped metamaterial slab for oblique incidence angles. The electrical size of the split-ring resonators was 1 order of magnitude smaller than the operation wavelength ~8.5 cm. We demonstrated that the left-handed transmission peak preserved up to an angle of incidence 45 degrees . The angular measurements w...
متن کاملMagnetically Tunable Ferrite-Dielectric Left-Handed Metamaterial
In this paper, a magnetically tunable metamaterial is proposed and studied. The metamaterial is based on the combination of ferrite sheets and dielectric rods. The tunable property is originated from the ferromagnetic resonance and electric response of dielectric rods. The retrieved electromagnetic parameters and transmission characteristic showed that by simultaneously inspiring the ferromagne...
متن کاملNovel Zeroth-order Resonance in Composite Right/left- Handed Transmission Line Resonators
A novel resonator using a composite right/left-handed (CRLH) transmission line (TL) is presented and its extraordinary resonant characteristics with an infinite-wavelength wave are discussed. The resonance corresponds to the zeroth-order on the analogy of the conventional mode numbering. The zeroth-order resonant characteristics and loss mechanism are fully described by the circuit theory and i...
