“…The initial resonance frequency of the patch (1) depends on the relative effective length; this length is conformed by the width of the patch and the length of the transmission line. The resonance frequency is expressed as [21][22][23]: Where l, p and r are, respectively, the diameter patch, the length of the transmission line and the relative effective length owing to the width of the patch (in centimeters). The effective length k is the quotient of the patch diameter and 2 .…”

In this article, the design and experimental characterization of a transparent MIMO fractal antenna compatible with 5G communications are presented. An Indium Tin Oxide (ITO) film with a thickness of 150 nm deposited over a glass substrate was used to fabricate the proposed antenna. This antenna is conformed by a pair of CPW-fed octagonal patch. Both patches were modified using a fractal structure, based on a Minkowsky geometry. The antenna was designed to operate in the frequency range from 3 to 5 GHz, which covers the C-band 5G-NR standard frequency assigment. As a result of the experimental characterization, S 1 1 and S 2 2 parameters are below − 10 dB, meanwhile the transmission coefficients S 2 1 and S 1 2 are under − 20 dB in the desired band. The Envelope Correlation Coefficient (ECC) is between 0.02 and 0.45, and a Diversity Gain (DG) over 9.05 in the frequency range from 3 to 6 GHz. These experimental results agree with the MIMO system in the required band.

This article proposes a microstrip bandpass filter patch antenna for remote access, particularly for vehicular applications. The antenna comprises split ring resonator (SRR) defected ground structure. The antenna design and filter are integrated to collaboratively work as filtenna (integrated filter antenna) for enhanced performance by reducing the total power consumption in the system. The objective of this paper is to carry out a detailed study of the effects of SRR parameters on the proposed filtenna. The investigation is carried out on the width of the slit opening of the SRR slot and the rotation of the inner square shaped ring structure in clockwise direction. The proposed filtenna is designed to provide a tuneable frequency operation. Simulation is performed on high frequency structural simulator which demonstrates good output response making filtenna design suitable for intelligent vehicular communication, particularly dedicated short-range communication-based applications at 5.9 GHz band and wireless local area network applications. The proposed filtenna is smaller in size, has low insertion loss, displays high selectivity and exhibits brilliant out of-band execution.

“…Fractal structures are preferred because of their main properties such as selfcorrelated, space-lling, and fractional ratios. Thus, fractal antennas are more bene cial over conventional microstrip patch antennas because they provide multiband/broadband behavior along with size miniaturization [6][7][8][9][10][11][12][13].…”

“…Depending upon the literature survey prepared in this concern; it is perceived that there are many shapes of fractal structures that are used in antenna designs such as Koch snow ake, Sierpinski carpet, Sierpinski gasket, Minkowski fractals, Moore, and Hilbert curve along with some different shapes over a period of time [7][8][9][10][11][12][13]. In addition, various researchers have presented some ideas related to cross, plusshape, and Chaucer shape fractal antennas due to their simple geometries.…”

This paper analyzes and compares the performance of a proposed cross-shaped fractal antenna design with two different substrate materials FR4 epoxy and lanthanum doped Ba-Sr hexagonal ferrite in X-band, where the lanthanum doped Ba-Sr hexagonal ferrite substrate is synthesized based on solid-state reaction method. The proposed antenna design is simulated using HFSS (High frequency structure simulator) version 15. The antenna is intended to work at 10 GHz frequency and involves four iterations. The antenna design is optimized for significant performance parameters viz. return loss, bandwidth, and gain. It provides better results with ferrite substrate as compared to FR4 epoxy substrate and provides − 10 dB broad bandwidth in three frequency regions 6.2969-6.4 GHz, 7.8702-9.44 GHz, and 9.68-9.7746 GHz. The prototype of proposed antenna with FR4 epoxy substrate is fabricated and tested to attain experimental results. The measured results are in good liaison with simulated results. This antenna structure can be considered suitable for RADAR, satellite, microwave communication, and weather forecasting applications in X-Band.
