A compact CPW‐fed circle inscribed hexagonal super wideband fractal antenna is presented. The radiating patch comprises three iterations of hexagonal patch loaded with circular slots. An impedance bandwidth of 2.75–71 GHz, that is, a bandwidth ratio of 25.82:1 is achieved by using asymmetric coplanar waveguide feeding and three iterations of circular slot loaded hexagonal radiating patch. Relatively stable omni‐directional radiation patterns are achieved over the operating frequency band. A good agreement is found between the simulated and experimental. The designed antenna has advantages of miniaturized size and wider bandwidth over the previously reported structures. © 2016 Wiley Periodicals, Inc. Microwave Opt Technol Lett 58:2794–2799, 2016

In this article, a compact design of the monopole antenna is proposed for the super‐wideband application (SWB). The extremely wide frequency bandwidth is achieved by deploying a topology based on trapezoid shape radiator, triangular tapered feed line, and semicircular ground. The antenna shows resonance from 1.42 GHz to more than 90 GHz with a bandwidth ratio of 63.30:1, VSWR ≤2 and with S11 ≤ −10 dB. The electrical dimension of the monopole antenna is 0.16λc × 0.27λc where the wavelength λc is with respect to the lowest cut‐off frequency. The designed monopole antenna is fabricated on the F4B substrate. The prototype is experimentally validated for ultrawideband and SWB application. The experimental and simulated results are in good agreement and the designed antenna shows better performance of a wideband operation, compact electrical dimension, and high bandwidth dimension ratio over existing reported structures. The proposed antenna can be used for multiple bands such are ISM, Wi‐Fi, WLAN, WiMAX, C, S, X, K, and Ku bands.

A quad‐port planar multiple‐input‐multiple‐output (MIMO) antenna possessing super‐wideband (SWB) operational features and triple‐band rejection characteristics is designed. The proposed MIMO configuration consists of four modified‐elliptical‐self‐complementary‐antenna (MESCA) elements, which are excited by tapered co‐planar waveguide (TCPW) feed lines. A radiator‐matched complementary slot is present in the ground conductor patch of each MESCA element. The proposed MIMO antenna exhibits a bandwidth ratio of 36:1 (|S11| < −10 dB; 0.97‐35 GHz). Further, a step‐like slit‐resonator is etched in the radiator to eliminate interferences at 3.5 GHz. A hexagonal shaped complementary split ring resonator (CSRR) is also loaded on the MESCA radiator to remove interferences at 5.5 and 8.5 GHz. The MIMO antenna is fabricated on FR‐4 substrate of size 63 × 63 mm2 and experimental results are found in good agreement with the simulated results. The MIMO antenna exhibits inter‐element isolation >17 dB and envelope correlation coefficient (ECC) <0.01 at all the four ports.
