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 کاملDeterminants of Zeroth Order Operators
For compact Riemannian manifolds all of whose geodesics are closed (aka Zoll manifolds) one can define the determinant of a zeroth order pseudodifferential operator by mimicking Szego’s definition of this determinant for the operator: multiplication by a bounded function, on the Hilbert space of square-integrable functions on the circle. In this paper we prove that the non-local contribution to...
متن کاملCpw-fed Zeroth-order Resonator Antenna Using Shorted Crlh Transmission Line
A novel composite right/left-handed (CRLH) coplanar waveguide (CPW)-fed zeroth-order resonator antenna is proposed. The shorted CRLH transmission line exhibits zeroth-order resonance at 2 GHz and operates with narrow bandwidth. The dispersion analysis is also carried out and presented in this article. The proposed antenna has been fabricated and tested. Omnidirectional radiation pattern with a ...
متن کاملA Wideband Zeroth-Order Resonance Antenna for Wireless Body Area Network Applications
A wideband on-body antenna for a wireless body area network for an Industrial, Scientific, and Medical band is proposed. A wideband characteristic is achieved by combining two zeroth-order resonance (ZOR) modes at adjacent frequencies by controlling the value of the shunt capacitance. The size of the proposed antenna is 0.072λ0 × 0.33λ0, and the measured 10-dB return loss bandwidth is 340 MHz (...
متن کاملCompact Metamaterial-Based Tunable Zeroth-Order Resonant Antenna with Chip Variable Capacitor
This letter presents a compact metamaterial-based tunable zeroth-order resonant antenna. It is based on the double-negative unit cell with a function of tunable inductance realized by a varactor and impedance convertor in the shunt branch. The resonant frequency of the designed antenna ranges from 2.31 to 3.08 GHz, depending on the capacitance of the used varactor. Its size is very compact (0.0...
