“…Later, another approaches presented recently based on smart coded metasurface including EBG layers as reflectors [15]- [20]. For instance, the proposed metasurface in [15] was designed to realize an 8-phase shift keying wireless transmitter. In [16], an ASK modulation technique was proposed based on switchable metasurface at THz applications.…”

In this paper, a novel structure of a reconfigurable Electromagnetic Band Gap (EBG) layer is presented for direct antenna Amplitude Shift Keying (ASK) digital modulation. Therefore, the modulation process, in this paper, is realized without the need to include conventional parts like filters, mixers or power amplifiers. Beside many advantages, the proposed modulation process offers cost, complexity, and weight reductions to suit many modern applications including 5G systems. The reconfigurable EBG layer has two statuses: ON and OFF. Each status produces a certain level of gain enhancement. Via controlling the reconfigurable EBG statuses, the amplitude of the transmitted wave can be controlled. The results show such a system design can modulate the electromagnetic signals directly by varying the gain from 2 dBi for logic_0 (OFF) to 11 dBi for logic_1 (ON). For this, a mathematical model based on ray tracing analysis is conducted to explain the principle of operation of the proposed EBG layer. The antenna and EBG structures fabrication as a system is realized and tested experimentally. The measurements show good agreements with the proposed mathematical model and CST MWS simulations.

“…In the past few years, different EBG designs are proposed to improve the performance of the patch antenna. [3][4][5][6][7][8][9][10] Gain enhancement of 2 dB for a circular patch is obtained with cylindrical mushroom EBG (MEBG) placed around the patch. 3 For a two-element aperture coupled antenna array designed on low-temperature co-fired ceramics substrate, MEBG is placed at the edge of the substrate which enhanced the gain by 4 dB.…”

“…7 An L-slotted MEBG is designed for coaxial fed patch antenna for enhancing the gain by 1.2 dB. 8 Another important application of EBGs is mutual coupling reduction in array antennas. A compact spiral EBG is designed and placed around the array to get a mutual coupling reduction of 5 dB.…”

In this paper, the application of the L‐slotted mushroom electromagnetic bandgap (LMEBG) structure to patch antenna and antenna array is investigated. A coaxial fed patch antenna and antenna array are designed at 5.8 GHz, center frequency for ISM band (5.725‐5.875 GHz). Two layers of LMEBG are placed around the patch to achieve a gain enhancement of 1.9 dB. Measured results show a bandwidth enhancement of 300 MHz with an additional resonant frequency at 5.6 GHz with 4.5 dB of gain. A 5 × 2 array of LMEBG is used to achieve a 2 dB mutual coupling reduction and 2 dB gain enhancement for a two‐element H‐coupled patch antenna array.

“…To make the communication more efficient, the gain of the microstrip antenna needs to be improved. Many different techniques have been used in the past to enhance the gain of the microstrip antenna such as using partial substrate removal [3], by inserting slots in the antenna design [4,5], using parasitic elements [6][7][8], EBG structures [9][10][11][12], artificial magnetic conductors [13,14], and metamaterials [15][16][17][18][19][20][21][22][23]. The use of metamaterial in antenna design is more efficient and effective as metamaterials show some unusual and interesting properties such as negative permeability and negative index of refraction [24] which they get from their uniquely designed structure that is not found in naturally occurring materials.…”

This article presents a Sub-6 GHz microstrip patch antenna (MPA) with enhanced gain using metamaterial (MTM) superstrate. The source MPA operates at 4.8 GHz and has a peak gain of 5.3 dBi at the resonance frequency. A window-shaped unit cell is designed and investigated through the material wave propagation technique. The unit cell shows an Epsilon Near Zero (ENZ)-Mu Very Large (MVL) behavior around 4.8 GHz. The unit cell has a fourfold geometry which makes it a polarization independent metamaterial. A double layer antenna is designed by placing a 4 × 4 MTM slab as a superstrate above the MPA at a height of 0.208λ 0 ; where λ 0 is the free-space wavelength at the resonance frequency of the antenna. Impedance matching and gain of the source antenna is improved using the metamaterial. The simulation as well as measurement results show that novel antenna system has a peak gain of 7.68 dBi at 4.8 GHz and an impedance bandwidth of 0.22 GHz. The overall dimension of the antenna is 75 × 60 × 15 mm3. The proposed antenna operates in the Sub-6 GHz band and is suitable for 5G applications.
