“…Whereas in [47][48][49], electromagnetic band gap (EBG) structures, also known under the name of photonic crystals were carried out to reduce, and in certain cases, to eliminate the surface waves, which lead to an increase in the directivity and the bandwidth. In this context Yang [50] was the first who proposed antennas with large gain, which could be carried out with a unique radiant element printed on a photonic band gap (2-D PBG) material.…”

Abstract-In this paper we studied the effect of a chiral-substrate bianisotropy on the surface waves of the microstrip resonator. The effective technique used to formulate the characteristic equations of the surface waves in a medium equipped with a complex anisotropy is presented and detailed. The equations concerning an evaluation of the cut-off frequencies are given in more detailed forms. A simple approximate formula for estimating the wave number of the surface mode TM 0 and TE 1 are obtained. An estimated maximum value of chiral slab thickness without the excitation of surface waves is given. All of our original results are compared with those published in the literature.

“…Recently a defected ground structure (DGS) have been introduced, DGS is realized by etching off a simple shape defected from the ground plane, depending on the shape and dimensions of the defect, the shielded current distribution in the ground plane is disturbed resulting a controlled excitation and propagation of the electromagnetic waves through the substrate layer. The dimension of the DGS is optimized for the band gap at the resonant frequency of the antenna by trial and error approach [19][20][21]. Dual frequency operation of antennas has become a necessity for many applications in wireless communication systems such as GPS, GSM services operating at two different frequency bands and services of PCS and IMT-2000 applications.…”

A novel gap coupled dual band multiple ring antenna with a defected ground structure (DGS) has been successfully implemented. A different technique is used in this communication where both gap coupling and defected ground are applied to obtain better results for wireless applications. The designed antenna operates in two different frequency bands. The antenna shows a wideband in C-band and also resonates in the X-band. The main parameters like return loss, impedance bandwidth, radiation pattern and gain are presented and discussed. The gain is increased and the side lobe level is considerably reduced to a good extent. Designed antenna is tested and the results show that the simulation and experimental results are in good agreement with each other.

“…In many cases, EBGs are used as planar reflectors, as substrates, or as high impedance ground planes: they are able to eliminate the drawbacks of conducting ground planes, to prevent the propagation of surface waves, to lower the device profiles, and to increase radiation efficiency [11,26,27]. Otherwise, EBGs can be employed as superstrates, and their effect is a considerable reduction of the angular range of the field emitted by the antenna [28][29][30].…”

Abstract-A deep analysis of the directivity enhancement, due to the insertion of a simple linear antenna into a dielectric EBG, is presented. The operative frequency is chosen near a band-gap edge. The planewave expansion method is used in order to obtain the Bloch dispersion diagrams of infinite two-dimensional EBGs. A rigorous cylindricalwave approach is used to analyze two-dimensional EBGs with finite size, excited by a line source. We apply these tools to the analysis of different emitting devices, and propose solutions to improve their performances.
