Design and analysis several band antenna for wireless communication

Abstract

This article describes the construction of a dual-band planar monopole antenna. A microstrip patch antenna with a feedline impedance of 50 ohm and a patch composed of G-shaped and inverted L-shaped strips is used to make the suggested antenna ultra wideband for frequencies ranging from 3.1 to 10.6 GHz. In order to design the antennas, we need to know the dimensions 40x40x1.6 mm3 and the thickness of the ground plane (0.035 mm) (5.2 GHz). There is a method of altering the present distribution by introducing slots. the proposed worldwide interoperability for microwave access (WiMAX) and wireless local area network (WLAN) bands, with a peak gain of 5.2% and an omnidirectional radiation pattern, suitable for ultra wide band (UWB) were shown to be viable.

A review of 2.45 GHz microstrip patch antennas for wireless applications

“…If the antenna and feed are not matched, then some of the available electrical energy will not be able to transmit to the antenna [41]. As a function of the VSWR, an antenna's reflection coefficient is shown here [42].…”

Single Layer Metamaterial Superstrate for Gain Enhancement of A Microstrip Antenna Array

“…Optimizing the configuration and arrangement of antenna elements within the array to achieve desired radiation patterns, beam steering capabilities, and side lobe suppression [9], utilizing multilayer stack configurations to add functionalities such as polarization diversity, frequency selectivity, and impedance matching [10,11]; mutual coupling often deteriorates an antenna array's radiation characteristics, to mitigate this, the element separation should be at least λ/2 (from center to center) to avoid mutual coupling and grating lobes [12], techniques to reduce mutual coupling include implementing electromagnetic band gap (EBG) structures [13], applying neutralization techniques [14], integrating stub transitions into the feeding microstrip line [15], etching slots or slits into the ground to create Defected Ground Structures (DGS) [16,17].…”
