Wide Slot Antenna With Y Shape Tuning Element for Wireless Applications

Abstract

Abstract-A wide slot antenna with Y shape tuning element is presented for wireless applications (GSM 1800, WiMAX, PCS and ITM-2000). The proposed antenna is fabricated on an FR-4 substrate (tan(δ) = 0.02, ε r = 4.3) with the thickness of 1.6 mm. On the top layer of the substrate, a 50 ohm microstrip line is fabricated which is terminated in Y shape tuning element. On ground plane, an irregular wide slot and triangular notch are etched. In addition, for performance improvement two triangular shaped parasitic slots are embedded on the ground plane. The proposed antenna is energized by the microstrip line. It exhibited the bandwidth of 127.55% from 1.15 GHz to 5.2 GHz for |S 11 | < −10 dB. Surface current distribution and radiation pattern at resonating frequencies 1.25, 1.9 and 4.2 GHz are analyzed. Impact of parameters on S 11 characteristic is also studied to know the behavior of the antenna.

Design of a wideband Y‐shaped antenna for the application in IoT and 5G communication

“…The compact Y-shaped antenna of Deshmukh et al 16 has a huge physical size of (38 Â 100) mm 2 , excited with a proximity feeding method, which is not suitable for high-frequency applications and also the operational bandwidth is narrow in contrast with our proposed antenna. The slot antenna of Shukla et al 17 with a Y-shaped impedance matching section has a very large physical size and bidirectional radiation pattern, which are the major differences with our proposed design. The notable distinction of the CPW fed Y-shaped antenna of Liu and Hs.…”

Improved Bandwidth of Microstrip Wide-Slot Antenna Using Gielis Curves

“…Researchers have explored various methods to enhance the bandwidth of wide-slot antennas, broadly categorizing these techniques into two groups. The first group involves strategies such as rotating the wide square slot [4], using multiple resonance technique [5,6], inserting parasitic patches and tuning stubs [7,8] and applying different feed shapes, like T-and cross-shapes, fork-like shape and square patch [9][10][11]. A survey of literature indicates that the second group is based on defected ground structures (DGS) including the use different shapes for slot such as triangular, tapered rectangular, E-shaped, circular and fractal geometries [12][13][14][15][16] to increase the antenna's bandwidth.…”

“…For instant, the antenna proposed in [16] has wide impedance bandwidth of 148.6% and an acceptable gain of 4.7 dBi, its size is large. To remove this 2 challenge, wide-slot antennas with irregular shapes and parasitic elements are merged together [17][18][19][20][21][22][23][24]. For instance, an irregular polygonal shaped wide-slot has been proposed in [17] with reduced size and an impedance bandwidth of 127.5%.…”

Design and Analysis of Minkowskized Hybrid Fractal Like Antenna for Multiband Operation

“…He explained the concept of a fractal and fractals abilities to reduce the size of an antenna without compromising its performance. Since then, various research concepts [6][7][8][9][10][11][12][13][14][15] related to fractal antenna have been revealed, and a new era of fractal antenna theory has begun. Various fractal antennas such as Sierpinski triangle [19], Koch dipole, meander and Minkowski fractal [16,17] show the advantages of fractal geometry over the popular fractal Sierpinski and Koch curve and become references.…”
