Novel Sequential Rotated 2x2 Array Notch ed Circular Patch Antenna

Abstract: This article presents a novel high gain rotated circular patch antenna operating at S-band. Circular patches are arranged with probe feeding in a particular order to get circular polarization. By employing sequential rotation technique, the proposed antenna is giving an impedance bandwidth of more than 40% (return loss less than-10 dB) and 3dB axial ratio bandwidth of 15% in the operating band with peak gain around 13 dB. Array antenna is fabricated on RT-duroid substrate and the measured results are showing g… Show more

“…The design of microstrip antenna for modern telecommunication and satellite communication with compact and conformal structure is the big challenge for researchers [1][2][3][4]. The conformal antennas may suffer with losses associated with material, connector and mismatched platforms etc [5][6][7][8][9].…”

“…There is a huge number of researchers are attracted to MIMO and mm-wave, but there are factors which are obstructing it gain its proficient stage like rain, distance between the transmitter and receiver [9]. MIMO share same plane, but the radiating elements are separated by a distance, due to which there might be a coupling effect between the radiating elements [10]. To reduce the effect of coupling few structures are being used in which one of the techniques is EBG, which reduces the wave spread, DGS is also a technique which can help through this effect of coupling [11].…”

“…The solid used here is FR4 epoxy with dielectric value 4.4 and Dielectric loss tangent 0.02. This design considered with 5 step staircase followed by rectangular patch & inverted π-shaped slot with requisite slots along with feed line to attain UWB range practically [13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28]. The proposed antenna is notched with two bands, WLAN and X-band satellite communication and a complete parametric analysis is done using HFSS tool.…”
