A compact multi‐band meanderline antenna for wireless communications applications

Abstract

impedances by using the results of synthesis formulas, are very close to the quasi-static analysis and experimental results.These comparisons obviously show that there are very good agreement among the results of the synthesis formulas, the quasistatic analysis, and experimental works. Self-consistent agreement has also been observed between the first and the second synthesis formulas. CONCLUSIONNew, simple, and accurate formulas for conductor-backed CPW synthesis have been presented in this article. The synthesis formulas have been tested by using the results of quasi-static analysis and experimental works available in the literature. Average percentage error of the characteristic impedances calculated by the new synthesis formulas is found to be better than 1% for 1086 conductor-backed CPW structures. The presented synthesis formulas allow the designers to obtain the physical dimensions of conductor-backed CPW for the required design specifications by a very simple and convenient way rather than by the iteration approach applying conventional design equations.

Individual Patch Antenna and Antenna Patch Array for Wi-Fi Communication

“…The design of patch antenna is realized in several areas, like GPS communication, cellular telephony, etc ( [9]). At commercial level, in the case of Wi-Fi networks, several variants have been implemented in routers, such as the use of patch antennas in antenna arrays (figure 2), or individual replacement patch antennas for indoors and outdoors (figure 3) [3].…”

Antenna miniaturisation and broadband design via a decomposition of structure into conjugated elemental antennas for natural impedance matching

“…Regarding the miniaturisation aspect, many past efforts have attempted to reduce the antenna size using one or more of the following three types of approaches. The first employs meander‐line structures to make the antenna's physical size compact while retaining the electrical length of the current flow path to achieve a desired resonance [7, 8]. These structures generally suffer from strong mutual coupling between the adjacent paths, and thus sacrifice radiation efficiency.…”

Miniaturized microstrip‐fed self‐resonant rectangular split‐ring resonator antenna

“…Presently, the trend is to provide a wireless link to every kind of electronic devices. In particular, there is a specific need for greater capacities and transmission speeds, which, together with a growing demand from users for more complicated services, require the design of higher performance systems [1]. As communication devices become smaller due to greater integration of electronics, the antenna becomes a significantly larger part of the overall package volume.…”
