“…The original design is split with reference to the center line at X=12.5mm. This causes the new two version of the miniaturization the design as right half and left half portion [6]. Both are symmetric to each other as the dimension of 12.5*30mm 2 with the thickness (H) of 1.6mm.…”

“…The proposed half cut antenna is implemented by applying the miniaturization concept on original antenna design. The parametric analysis is covered the frequency band from 3.1 GHz to 10.6 GHz, which associated with the UWB band [6]. The Simulation process is involved the comparative measurement of reflection coefficient [S11] and Voltage Standing Wave Ratio [VSWR] over the frequency range [8].…”

A 50-ohm Coplanar Waveguide feed antenna is used as a monopole half cut antenna having half fork-shaped radiating patch and extended ground plane to cover frequency band 3.1 GHz to 10.6 GHz. As the proposed antenna provides frequency coverage for UWB frequency spectrum. A half cut technique is used for the miniaturization of the antenna. This antenna provides worldwide compatibility for communication among of Microwave frequency band from 3.1GHz to 10.6 GHz. This literature covers the effects of miniaturization on the reflection coefficient [S11 Parameter] and VSWR. A comparative study of antenna parameter here I discussed. Enhance the performance of the antenna in terms of constant gain, radiation pattern, and impedance matching directivity. The parametric analysis and prototype simulation has been done with the help of An-soft HFSS.

“…Modifying the feeding scheme of the half‐size antenna can provide better impedance matching than the original antenna. However, this method cannot be generalised because the high‐input impedance that halved the feeding line imposed on the antenna results in unstable impedance matching [1, 3].…”

In this study, an effective methodology to design a compact four-element multiple-input-multiple-output (MIMO) antenna with high performance over ultra-wide bandwidth (BW) is presented and discussed. Taking the advantages of symmetry of most planar ultra-wideband (UWB) antennas, an asymmetric feeding scheme technique is utilised to chop a previously developed UWB slot antenna with overall dimensions of 30 mm × 30 mm into two halves to yield a more compact structure while retaining its overall frequency-and time-domain performances. Benefiting from orthogonal orientation, a compact UWB MIMO antenna system is arranged using four half-sized elements. The proposed MIMO antenna has an overall size of 40 mm × 40 mm and exhibits impedance BW from 2.94 to more than 14 GHz (10 dB return loss) with port isolation better than 17 dB over the entire operating band without using any decoupling structures. This is achieved via the inherent directional radiation properties of slot antenna elements and their asymmetrical placements. Envelope correlation coefficient is computed, and it is within the acceptable limit, which validates the design concept for building a compact MIMO antenna system with good performance.

“…Hence compact and broadband MIMO antenna offers good solution in this respect. Half-cut technique [1] provides miniaturization method for broadband antenna but in many cases it degrades impedance matching condition of many antennas [2,3]. In MIMO, it may also worsen isolation among antennas [2].…”
