The focus of discussion in this paper is an acceptable small configuration for an elliptical microstrip patch antenna. This is featured with planer geometry embedded mirror ellipse with elliptical notch layout. It can be used for multiband application in wireless communication. The chosen antenna produces seven echoing frequencies that operate across the frequency range of 5 to 18 GHz, including 5.9 GHz (use in WiMAX), 8.2 GHz, 9.99 GHz (use in X- band), 12.63 GHz (use in space services and within rise-data-rate), 13.97 GHz (land portable spacecraft, broadcast navigating implementation), 16.24 GHz and 17.57 GHz (use in Ku- band). The proposed antenna has mirror-imaged elliptical slots with embedded ellipse in slots having the microstrip signal line feed without any defects in the ground structure. A simulation tool that uses the finite element modelling set up (ex. CST) created the potential antenna. On a dual-sided FR-4 substrate (ɛᵣ = 4.3) with a layer thickness ‘h’ of 1.6 mm and a surface size (Ls× Ws) of 20 x 24 mm², the recommended antenna is modelled. The outcomes of the simulations show the fact that our presented antenna has satisfactory gain and S11 ≤ -10 dB input impedance bandwidths across seven working frequencies. This offered antenna design concept is a major contender for multiple purposes in wireless communication and is backed by resonant frequency regions spread throughout a broad spectrum.

“…for designing MIMO antennas with the ultimate goal to achieve miniaturization and multiband/wideband frequency response. All the previously designed fractal MIMO antennas [8][9][10][11] had larger dimensions, less port-to-port isolation and were employed for multiband wireless systems. Based on the literature review, the primary objective of this article is to design, simulate and experimentally test a miniaturized fractal MPA array for high bandwidth and good diversity performance to support high data rate portable UWB systems.…”

In this manuscript, a two-port semi-circular patch antenna with Koch curve fractals is presented as a suitable candidate for portable UWB communication systems. The proposed fractal array is engraved on a 1.57 mm thick FR-4 substrate with an overall array size of 30.5 × 47 × 1.64 mm3. The upper substrate layer consists of two microstrip-line fed semi-circular patches combined with two Koch curve fractals (optimized up to 2nd order of iteration) separated by a distance of λ/2. To mitigate the effect of mutual coupling between the radiating elements, the lower substrate layer consists of a reduced ground plane with a funnel-shaped decoupling structure. To achieve a high degree of isolation (S21/S12 [?] -16.8 dB) between the ports of the proposed array, two rectangular and L-shaped slots (mirror images of each other) are etched from the upper surface of the reduced ground. The design and simulation of the proposed antenna array is implemented in CST MWS'18. The optimized fractal array covers the simulated frequency band from 4.395-10.184 GHz with a fractional bandwidth of 79.4 % (at a center frequency of 5.789 GHz) and provides a peak radiation efficiency of 88.8% (at 6.2 GHz frequency). The antenna diversity performance is analyzed in terms of envelope correlation coefficient (ECC [?] 0.0021), diversity gain (DG [?] 9.989), mean effective gain (MEG [?] -3.7 dB), channel capacity loss (CCL [?] 0.4 bits/s/Hz) and total active reflection coefficient (TARC [?] -10 dB). The experimentally measured S-parameter results show a good match with the simulated ones.
