“…In this article, a 2x2 rectangular planar array antenna with probe feed on the Rogers RT/Duroid 6010. For avoiding any grating lobe the biggest spacing between the radiating elements should be <1λ [24]. According to the transmission line model, the feedline length is always λ/4 [25], in order to attain the best potential impedance matching between the transmission line and the patch elements.…”

<p>A novel design of EBG is used to replace the mushroom like EBG for surrounding the array patch antenna. In order to improve its radiation performances, Electromagnetic band stop for reducing the surface waves effects is presented. The novel design of Triple Side Slotted EBG (TSSEBG) showed an improvement in the antenna efficiency, directivity and gain as compared to the reference antenna without using EBG, due to reduce the surface waves effects which leads to decrease the side lobes. TSSEBG has been introduced by some modifications in conventional mushroom-like EBG structure. Reducing the complexity was achieved by reducing the number of unit cells and vias, in case of used TSSEBG instead of mushroom like EBG. Additionally, the TSSEBG provided triple band gap compared with mushroom like EBG structure which had only one band gap frequency at 6 GHz. The placement of TSSEBG is a flexible structure which provides a good choice in the antenna applications. The simulation results of array patch antenna with and without mushroom like EBG and TSSEBG are arranged in Table 1. This structure has vast applications in satellite communications.</p>

“…An efficient design methodology has been proposed for the impedance matching of an aperture‐coupled stacked patch antenna for improving the bandwidth . Mushroom‐like EBG, mushroom‐like PBG, and UC‐PBG‐metamaterial based structures have also been suggested for enhancing the operating bandwidth of MSAs, respectively. PBG‐coplanar waveguide (PBG‐CPW) structured antenna has been demonstrated for increasing the bandwidth of microstrip antennas.…”

Wireless communication systems are playing an important role in different sectors of human society. Printed antennas are considered as the critical enabling technologies for these systems. The technology related to the design and development of printed antennas have been continuously improved from the structural view of configuration to antenna features improvement. Electromagnetic bandgap (EBG) structures have played a significant role in improving the features of printed antennas. In this paper, authors have restricted a feature–oriented comprehensive survey on EBG‐structured printed antennas. This type of survey is primarily required for the beginner working on EBG structures/EBG‐structured printed antennas. Such a survey process is rarely carried out in the open literature to the best of authors' knowledge. The proposed survey process is confined only to five different feature classifications; bandwidth improvement, gain improvement, dual‐band/multi‐band characteristics, band‐notch characteristics, and compact and low profile, respectively.

“…The microstrip antenna can usually be excited by a coaxial‐feed, an edge‐feed, an inset‐coupled feed [1], a proximity‐coupled feed [2], or an aperture‐coupled feed [3]. Among them, the feed line has a direct contact to the antenna in the former two methods, while the feed line is coupled to the antenna in the latter three methods.…”
