A new approach of the iterative method WCIP (Wave Concept Iterative Process) using the technique of the auxiliary sources considers a pixel or a unit cell in a periodic structure as an electrical circuit instead of a sub-domain representing metal or dielectric in the classical iterative method. The intersection of this new approach with the old is on the application of the iterative process in waves...
The theory of a novel approach of the WCIP method to analyze periodic lumped circuits has been presented. Transmission lines in their planar form (microstrip technology) can be modelled by an equivalent periodic lumped circuit that permits a fast analysis instead of the use of many electromagnetic full wave simulators which require a great running time and great memory size. The validation of the...

In this paper, a multilayer conical dielectric resonator antenna (DRA) excited by two coaxial cables has been investigated. The phase shift of the two coaxial cables with 90° creates a circular polarization of the radiated electromagnetic wave. The proposed structure provides a bandwidth of about 41% with a gain ranging from 4.8 dB to 8.7 dB in the bandwidth. The simulation study of the proposed antenna...
In this paper, we propose a dual layer conical Dielectric Resonator Antenna (DRA) excited by a slot. The inclination of the two environments with different dielectric constants relative to the slot can create a Circular Polarization (CP). Simulations performed under Ansoft HFSS software show that the proposed conical shaped DRA is circularly polarized and can reach a large bandwidth of 1.14 GHz with...
This paper is specialized to highlight the method of miniaturization and improvement the patch antenna by using the complementary metamaterial. This method is shown by two structures composed of a patch antenna integrated on its upper surface a cell of a complementary split ring resonator for the first technique. In the second structure, we replace the unit cell with a homogeneous and periodic array...
This paper focuses in the first part to demonstrate the correlation between the physical quantities of nested split ring resonators and its frequency characteristics. The investigation is conducted in a parametric study based on the simulation results and the theoretical proofs. The second part is reserved for our proposed approach to develop the method of improvement and miniaturization of RFID antennas...
In this article, we propose a new approach to study a suitable structure of metamaterial antennas for RFID technology that operates in the UHF band. This antenna is constituted by a dipole associated to a network specific and homogeneous structure composite of circular split ring resonators that can produce a negative permeability. Thanks to the effect of effective negative permeability, we can improve...
The article in hand deals present a new approach focuses on the electric modelling of split ring resonators based on an equivalent circuit. The elements of circuit are determined from geometric parameters forming the three dimensional model of this type of resonators.
