“…Beside the above discussed configurations, completely planar EBG microstrip antennas was also reported very recently [38,72,73]. The SRS-EBG proposed by Alam et al [38] was investigated as an artificial ground plane for an umbrella shape monopole antenna, which provided a wider bandwidth (from 9.26% to 11.25%), deeper return loss (from −26 to −31 dB), and higher gain (from 4 to 5.5 dB) than that A high-impedance periodic structure can be treated as an AMC or EBG, depending on their certain properties.…”

Hadarig et al [72] examined a microstrip antenna with same EBG structure in two ways-surrounding the patch antenna (EBG) and replacing the ground plane with the same structure (AMC). To apply as a ground plane, reflection phase characteristics are tested whilst transmission band gap is determined by the suspended microstrip line method to surround the patch.…”

Electromagnetic band gap (EBG) technology has become a significant breakthrough in the radio frequency (RF) and microwave applications due to their unique band gap characteristics at certain frequency ranges. Since 1999, the EBG structures have been investigated for improving performances of numerous RF and microwave devices utilizing the surface wave suppression and the artificial magnetic conductor (AMC) properties of these special type metamaterial. Issues such as compactness, wide bandwidth with low attenuation level, tunability, and suitability with planar circuitry all play an important role in the design of EBG structures. Remarkable efforts have been undertaken for the development of EBG structures to be compatible with a wide range of wireless communication systems. This paper provides a comprehensive review on various EBG structures such as three-, two-, and onedimensional (3D, 2D, and 1D) EBG, mushroom and uniplanar EBG, and their successive advancement. Considering the related fabrication complexities, implementation of vialess EBG is an attractive topic for microwave engineers. For microstrip antennas, EBG structures are used in diversified ways, which of course found to be effective except in some cases. The EBG structures are also successfully utilized in antenna arrays for reducing the mutual coupling between elements of the array. Current challenges and limitations of the typical microstrip antennas and different EBG structures are discussed in details with some possible suggestions. Hopefully, this survey will guide to increasing efforts towards the development of more compact, wideband, and high-efficient uniplanar EBG structures for performance enhancement of antenna and other microwave devices.

“…The thickness of FR-4 substrate is h = 2.5 mm with a relative permittivity of 4.4 for both AMC elements in this design. According to [21,22], the uniplanar AMC and EBG structures have different properties and operating bandwidths. In order to obtain the in-phase reflection band-gap, the periodic boundary condition is used to design the AMC element in the process of simulation, which is based on the Bloch-Floquet theory and on the finite element.…”

Abstract-Two different kinds of artificial magnetic conductors (AMCs) are used to reduce the out-ofband radar cross section (RCS) of microstrip patch antenna. The principle of this method is based on the high impedance characteristic of the AMC structures. The simulated results show that out-of-band RCS of the proposed patch antenna is much lower than that of the reference antenna over the frequency range of 5-12 GHz. The in-band scattering characteristic of the microstrip patch antenna is analyzed, and two slots are cut on the patch antenna to reduce in-band RCS. Prototypes of the reference and designed antennas are manufactured and tested, and the measured and simulated results of the two antennas are in good agreement.

“…In this paper, different shapes of high-impedance surface structures were introduced as mushroom, ring, split ring resonator, and spiral shape cells, respectively, as shown in Figure 3 to produce wide or dual band gaps and as a means to suppress surface waves effectively [18][19][20]. The configurations of transmission line over the 7 × 5 cell arrangement used to test the proposed EBG structures are shown in Figure 4.…”

The fourth mobile generation requires of multistandard operating handsets of small physical size as well as has an increasing demand for higher data rates. Compact multiband printed inverted-F antennas (IFAs) for available wireless communications are proposed in this paper. A new design of a printed IFA based on a uniplanar compact EBG concept is proposed. An L-loaded printed IFA shaped over an artificial ground plane is designed as the main antenna to cover the GSM, LTE, UMTS, bluetooth, and WLAN. The multi-band is created by means of an electromagnetic band-gap (EBG) structure that is used as a ground plane. Different shapes of uniplanar EBG as ring, split ring resonator, and a spiral rather than mushroom-like structure are investigated. The proposed antenna is built on the uniplanar EBG ground plane with a size of 35 × 45 mm 2 , which is suitable for most of the mobile devices.
