“…In this work, the hexagonal geometry is adopted as a radiating element to design the MIMO antenna systems since it has smaller size and can be designed by using variation of static energy below the square or circular monopole antennas [22]. In the MIMO system, each element is a hexagonal-ring monopole antenna (HRMA), and a CPW-fed line is used to feed this antenna.…”

Abstract-This paper presents a new design approach for compact orthogonal broadband printed multiple-input multiple-output (MIMO) antennas based on a coplanar waveguide (CPW)-fed hexagonalring monopole antenna (HRMA) element. The design procedure of the basic radiating element is initiated from a stripline (SL)-fed circular monopole antenna (CMA). Then various antennas involved in the design evolution process are introduced to attain a compact CPW-fed HRMA. This basic antenna element has a compact size of 13 × 10 mm 2 , 50% smaller than SL-fed CMA, and a prototype of this antenna is built and tested. Based on HRMA element, compact two-and four-element MIMO antenna systems are designed, fabricated and experimentally demonstrated for 5-GHz ISM band operation. The MIMO antenna systems use orthogonally configured of identical closely spaced HRMA elements, with CPW-fed printed on one side of the substrate to achieve good isolation. Design simulation is carried out with the aid of Computer Simulation Technology Microwave Studio (CST MWS) and confirmed with High Frequency Structure Simulator (HFSS). The experimental results are in close agreement with the simulated ones, which validates the design principle. Based on experimental results, the two MIMO antenna systems have an impedance bandwidth of more than 2 GHz, good isolation of less than 15 dB, and a low envelope correlation coefficient of better than −26 dB across the frequency band of (4-6 GHz), which are suitable for 5-GHz MIMO applications.

“…The HISs and AMCs are also known as Electromagnetic Band Gap (EBG) structures and Frequency Selective Surfaces (FSS). FSSs are used to enhance the impedance bandwidth and gain of an antenna [4][5][6][7]. In addition, FSS superstrate is also used as a polarizer to get circular polarization in case of single source excitation and it can also rotate the linearly polarized waves by 90 • in a given frequency band [8][9][10][11].…”

Abstract-A compact, low profile, dual polarized, ultra wideband, frequency selective surface is proposed. It is designed by using two similar metallic array structures separated by dielectric material FR4. The simulated reflection bandwidth (with transmission < −20 dB) for TE incident wave is 8 GHz from 2.87 GHz to 10.87 GHz corresponds to 116%. The unit cell dimension and periodicity are of the order of 0.37λ at the centre frequency. The overall thickness of the proposed FSS is 1.8 mm.The proposed FSS has higher order of band-stop response and good angular stability. The measured transmission response of FSS is very close to simulated response. Design expressions for the resonance frequencies are proposed, and the calculated results are found to be in good agreement with the simulated ones. Finally, a parametric analysis of the proposed FSS is presented.
