Study on a fractal electromagnetic bandgap structure

2015 Asia-Pacific Microwave Conference (APMC), 2015
A novel fractal Two-Dimensional electromagnetic bandgap(EBG) Structure is proposed. The fractal EBG is obtained by digging triangles of different sizes. The number of fractal order affects the operating frequency and bandwidth of the EBG structure. Transmission characteristics of the structure is validated by the suspengding microstrip method (SMM ...

Novel metallodielectric electromagnetic bandgap structure

Microwave and Optical Technology Letters, 2008
AbstractThis article is concerned with a novel microstrip EBG structure, formed by etching a shape into the signal line. Previous publications announced a lumped‐element equivalent circuit for the structure. This article gives simple equations for computing the equivalent circuit element values.

Scan blindness-free electromagnetic bandgap phased arrays

2017 IEEE International Symposium on Antennas and Propagation & USNC/URSI National Radio Science Meeting, 2017
A new type and multifunctional electromagnetic bandgap material, i.e. bandgap-antenna structure, is used as an antenna element in a planar phased array configuration. The structure provides mode-free bandgap, antenna, and phased array element characteristics simultaneously. A stripline impedance matching network is used to match bandgap-antenna element'

Equivalent Circuit Models for Evaluation of Bandgap Limits for Planar Electromagnetic Bandgap Structures

2010 IEEE International Symposium on Electromagnetic Compatibility, 2010
In this work different physic based equivalent lumped element circuits models representing planar EBG structures are developed. Their results, in terms of evaluation of the lower and upper limits of the bandgap, are compared with a three dimensional simulation considered as reference.

Analysis of Electromagnetic Bandgap Based Filters in a Rectangular Waveguide

IEICE Transactions on Electronics, 2006
Electromagnetic crystals formed by vertical full posts stacked in a rectangular waveguide are analyzed using the image theory and the lattice sums technique. It is shown that the frequency response of the crystals consisting of circular posts can be obtained by a simpler matrix calculus based on the one-dimensional lattice sums, the T-matrix of a ...

Electromagnetic bandgap structures in planar circuit technology

IEEE Antennas and Propagation Society Symposium, 2004., 2004
EBG structures can be implemented in planar circuit technology by applying a periodic perturbation function on the host transmission line. By doing so, frequency selective behavior can be imposed on the original transmission line, such as a microstrip line or a coplanar waveguide.

Characterizations of interconnects formed in electromagnetic bandgap substrates

Proceedings. 9th IEEE Workshop on Signal Propagation on Interconnects, 2005., 2005
In this paper, several interconnect geometries - single interconnect and multiple lines - formed in electromagnetic bandgap substrates are investigated through simulations and measurements. Microstrip lines are used as a benchmark to evaluate the performance of the prototype structures.

A circularly polarized antenna with electromagnetic bandgap structures

2015 Computational Electromagnetics International Workshop (CEM), 2015
In this paper, we propose a novel method to increase the axial ratio bandwidth of a circularly polarized microstrip patch antenna. Demonstrated method consists of polarization dependent rectangular-shaped mushroom-like electromagnetic bandgap structures positioned around circularly polarized radiator patch. Since the structure itself has a polarization-

Novel electromagnetic bandgap structure fabricating method

IEEE Antennas and Propagation Society International Symposium (IEEE Cat. No.02CH37313), 2003
This paper presents a new method for fabricating an electromagnetic bandgap structure. The periodic lattice pattern is buried in the substrate. No drilling through the substrate is required, and the integrality of the ground plane is kept. The structure is formed from two circuit boards. The periodic lattice is etched on the top face of the lower board
