Experimental Studies of Antenna Miniaturization Using Magneto-Dielectric and Dielectric Materials
Antti O. Karilainen, Pekka M. T. Ikonen, Constantin R. Simovski +5
Measurement results for a meandered planar inverted-F antenna (PIFA) loaded with magneto-dielectric and dielectric materials are presented. Figures of merit and ways to compare ant…
Electrically small metamaterial-based antennas - have we seen any real practical benefits?
Pekka Ikonen
Electrically small metamaterial-based antennas are discussed from the industrial point of view using mobile phones as the application example. It appears, that despite the interest…
Mesoscopic effective material parameters for thin layers modeled as single and double grids of interacting loaded wires
Pekka Ikonen, Elena Saenz, Ramon Gonzalo +2
As an example of thin composite layers we consider single and double grids of periodically arranged interacting wires loaded with a certain distributed reactive impedance. Currents…
Magnification of Subwavelength Field Distributions at Microwave Frequencies Using a Wire Medium Slab Operating in the Canalization Regime
Pekka Ikonen, Pavel Belov, Constantin Simovski +2
Magnification of subwavelength field distributions using a wire medium slab operating in the canalization regime is demonstrated using numerical simulations. The magnifying slab is…
On the Definition of Effective Permittivity and Permeability For Thin Composite Layers
Elena Saenz, Pekka Ikonen, Ramon Gonzalo +1
The problem of definition of effective material parameters (permittivity and permeability) for composite layers containing only one-two parallel arrays of complex-shaped inclusions…
Modeling and Analysis of Composite Antenna Superstrates Consisting on Grids of Loaded Wires
Pekka Ikonen, Elena Saenz, Ramon Gonzalo +1
We study the characteristics and radiation mechanism of antenna superstrates based on closely located periodical grids of loaded wires. An explicit analytical method based on the l…
