U‐shape broadband monopole antenna with modified ground plane

Abstract

In this article an U‐shape broadband monopole antenna with rectangular slots loaded ground plane has been designed and analysis. The proposed antenna covers the frequency band of (1.55–8.55 GHz) with multiresonating frequency at 1.65, 2.9, and 7.95 GHz. The effect of movement of radiating patch on the dielectric substrate and the effect of slots on the ground plane are studied. The maximum impedance bandwidth of 138% (simulated) and 142% (measured) with maximum peak gain 3.59 dBi (simulated) and 4 dBi (measured) are obtained. It is very much useful in modern wireless communication systems as an electronics device. © 2016 Wiley Periodicals, Inc. Microwave Opt Technol Lett 58:2544–2547, 2016

Design of a Compact CPW-Fed Monopole Antenna With Asymmetrical Hexagonal Slot Loaded Ground Structure for C/X/Ku Band Applications

“…Hence, the compact size antenna can easily be imbedded in small devices and MMICs for modern applications. However, the impedance bandwidth (4.86 to 13.66) / 8.8 GHz of the proposed antenna is greater than the impedance bandwidth of the antennas reported in [16], [17], [19], [20] by 800 MHz, 750 MHz, 1800 MHz and 390 MHz, respectively, and lesser than that of the antenna reported in [18] by 200 MHz.…”

Metamaterial inspired CPW‐fed compact antenna for ultrawide band applications

“…The microstrip UWB antennas have several advantages like high data speed, low power consumption, cost effective, minimum interference, and easy to install. Therefore, several works have been carried out for UWB technology and researchers have been developed number of UWB antennas …”

“…Therefore, several works have been carried out for UWB technology and researchers have been developed number of UWB antennas. [2][3][4][5][6][7][8][9][10][11][12][13] The log periodic and spiral antennas have now been under consideration for UWB applications which suffer from ringing effect along with larger size. 2 A directional Vivaldi antenna is illustrated in Reference 3 which is not suitable for indoor and portable devices.…”

“…Some of the researchers have been developed different techniques to achieve wide-band antenna for UWB applications. [5][6][7][8][9][10][11][12][13] The slot over the patch, [5][6][7] stacking of the patch antenna, 8 use of parasitic elements, 9 radiating patch with partially ground plane, 10 monopole antenna with modified ground plane, 11 fractal geometry 12,13 techniques have been developed for bandwidth improvement. Recently, some of the metamaterials based patches have been demonstrated for UWB application in References 14-17.…”
