“…The derived performance of the DGS is not fully predictable until the optimized solutions are achieved through a trial-and-error iterative process. Hence, the conventional methods reported in the literature [14,15] are time-consuming and may not lead to optimum design. The impedance bandwidth could be further enhanced by applying different sizes of ground plane lengths.…”

Abstract:An ultrawideband antenna array using a right-angled isosceles triangular microstrip antenna as a basic element is presented using inset feed for applications in the Internet of things. A Koch fractal antenna array with defected ground plane is used to generate multiband applications. Further, meander lines are added to increase the equivalent inductance that reduces the size of the antenna and increases the bandwidth and gain. Antenna arrays have been constructed and experimentally studied. The measured results show good agreement with the numerical prediction and wideband operation.

“…The behavior of radiating patches in transmission networks has been improved by using array antennas as it increases the efficiency [15][16][17]. Array performance is affected by fractal type, spacing between elements, * Correspondence: vinitamathur12@gmail.com feed point location, and number of parasitic elements.…”

“…A major disadvantage of their narrow bandwidth can be overcome by using specific design techniques with these antennas. Some of the methods available in the literature for bandwidth improvement include the use of slots in the antenna, , use of defected ground structures and use of fractal antenna geometry , . Fractals are self‐similar structures derived from naturally occurring patterns.…”

This research work reports the design and development of a novel complementary Sierpinski gasket fractal microstrip antenna array to achieve a good impedance bandwidth and hence support high data rates for 4G/5G MIMO applications. The proposed array is a compact structure (136 mm × 136 mm) designed with complimentary Sierpinski gasket fractal up to two iterations and has a defected ground to improve the antenna's performance. The antenna performance reports an 8.2% bandwidth at the center frequency of 4.94 GHz (4.7434‐5.1514 GHz), a simulated diversity gain of 9.99 allows the proposed array to be well suitable for proposed applications and a directivity of around 5.8 dBi suits good range characteristics. The array designing and optimization is carried out with 3D EM tool CST MWS V'14 using perfect boundary approximations. A simulated low value of envelope correlation coefficient (0.04) indicates that the two antennas in the array provide least interference to each other while radiating. The measured S11 results on a VNA E 5071C show a close match with the simulated results. Thus a compact array size with good bandwidth, radiation characteristics, low ECC and a high diversity gain allow the antenna array to be well suitable for portable MIMO 4G/5G wireless applications specifically for C band and military applications.
