“…This improves the power delivery from source to the patch, that will ensures the maximum radiations from the antenna. Also wide band antennas [7][8][9] are also playing significant role modern communications systems. In past, many mm-antennas [11][12][13][14][15][16] were developed to achieve mm-wave frequency range.…”

A low cost microstrip antenna is designed for mm–wave applications on FR4 substrate. It consist of patch, etched with an open polygon slot (OPS) at lower central edge of it and partial ground plane. This etching of OPS is used to improve depth of reflection co-efficient below -20 dB which is equivalent to mismatch loss (ML dB ) ≤ 0.04 dB. This proposed mm–wave antenna also provides 3 dBi– & 5 dBi–gain-bandwidth of 6 GHz (34.72—40.72GHz) & 3.91 GHz (34.72—38.63GHz) respectively with a peak gain of 12.4 dBi at 35.1 GHz and acceptable radiation efficiency of 58.05 %. Simple design, low manufacturing cost and ease of fabrication makes proposed antenna suitable for high end practical mm–wave applications.

“…Also, the present wireless communication networks suffering from latency, network load, severe infrastructure issues and other several problems. The enormous frequency range like mm-wave spectrum may be optimum solution to handle this necessarily trend of data growth and channel capacity (Malik et al , 2020; Rappaport et al , 2013; Khinda and Tripathy, 2015). Therefore, World Radio-communication Conference (WRC) (Marcus, 2017) continuously suggested fixing the mm-wave spectrum for majority of applications time to time.…”

Purpose A compact low-cost antenna structure is proposed to augment the impedance-bandwidth in mm-wave range. Beside it, the paper also aimed to enhance high gain for n260 and n261-bands, suitable for futuristic communication systems. Design/methodology/approach Design consists of radiating patch and a partial ground plane with semi-circle arc for smooth flow of current. The lower corners of patch are gradually clipped away to make the patch nearly elliptical. Further, two tilted slots at an angle α = 15° are etched at the edges of the patch to augment bandwidth for mm-wave range. These slots divert the periphery current of semi elliptical patch towards center portion of antenna which ensures the participation in radiation of central portion of patch. The upper corners are also clipped away to limit the copper losses and smoothly flow of current. The proposed antenna is designed using HFSS and it is structured on inexpensive FR4 substrate of size 27.5 × 20 mm2. Findings It supports enormous −10 dB bandwidth of 5.86–40GHz (148.89%) even though use of high loss-tangent material and high gain for 28 GHz (27.50–28.35 GHz) n261–band and 37 GHz (37–38.6 GHz) and 39 GHz (38.6–40GHz) n260–bands with a peak-gain of 8.76 dBi, 10.8 dBi and 9.92 dBi, respectively. Originality/value The proposed methodology of design is very useful to enhance impedance bandwidth to cover all C–, X–, Ku–, K– and Ka–band even though use of low cost material with high loss tangent. In recent literature, the designs were implemented with a costly material and having very low loss tangent and covers partial suggest bands.
