This paper presents a compact planar multiple input multiple output (MIMO) antenna for super wide band (SWB) applications. The presented MIMO antenna comprises two identical patches on the same substrate. Dimensions of the MIMO antenna are 0.17λ × 0.20λ × 0.006λ mm3, with respect to the lowest resonance of 1.30 GHz. The SWB antenna was manufactured using F4B substrate having a dielectric constant of 2.65 that provides a percent impedance bandwidth and bandwidth ratio of 187% and 30.76:1, respectively. The mutual coupling between the antenna elements is suppressed by placing a T-shaped corrugated strip in the mid of two antenna elements. The proposed MIMO antenna exhibits maximum diversity gain of 10 dB, low mutual coupling (<−20 dB), low envelope correlation coefficient (ECC < 0.02), efficiency >80%, and low reflection coefficient (<−10 dB) in the SWB frequency range (1.30 GH–40 GHz). The presented antenna is a good candidate for SWB applications. The designed antenna has been experimentally validated, and the simulated results were also verified.

“…The bandwidth (BW) ratio of SWB antennas is greater than 10:1. Multiple wideband antennas have been designed for UWB [1][2][3][4][5] and SWB [6][7][8][9][10][11][12][13][14][15] applications. The large dimensions/size of such wideband antennas is a major challenge.…”

“…In [11], an octagonal-shaped radiating patch antenna using the second iteration of the fractal shape was suggested. A monopole antenna comprising an egg-shaped radiating patch and a ground plane loaded with complementary semi-elliptical shaped fractal slot was developed in [12]. However, SWB antenna configurations using fractal shapes are difficult to manufacture, and practically only a few iterations are possible to design.…”

A compact, low-profile, coplanar waveguide (CPW)-fed quad-port multiple-input–multiple-output (MIMO)/diversity antenna with triple band-notched (Wi-MAX, WLAN, and X-band) characteristics is proposed for super-wideband (SWB) applications. The proposed design contains four similar truncated–semi-elliptical–self-complementary (TSESC) radiating patches, which are excited through tapered CPW feed lines. A complementary slot matching the radiating patch is introduced in the ground plane of the truncated semi-elliptical antenna element to obtain SWB. The designed MIMO/diversity antenna displays a bandwidth ratio of 31:1 and impedance bandwidth (|S11| ≤ − 10 dB) of 1.3–40 GHz. In addition, a complementary split-ring resonator (CSRR) is implanted in the resonating patch to eliminate WLAN (5.5 GHz) and X-band (8.5 GHz) signals from SWB. Further, an L-shaped slit is used to remove Wi-MAX (3.5 GHz) band interferences. The MIMO antenna prototype is fabricated, and a good agreement is achieved between the simulated and experimental outcomes.

“…Recently, few SWB antennas have been investigated by many researchers in the published literature [3][4][5][6][7]. Unfortunately, it is to be noted that some of the existing narrow-band systems such as WiMAX (3.3-3.6 GHz), C-band (3.7-4.2 GHz) and X-band satellite communication systems operating in 7.25-8.395 GHz (for down link: 7.25-7.745 GHz and uplink: 7.9-8.395 GHz) may cause electromagnetic interference (EMI) to the SWB system.…”

In this article, a simple and compact dual bandnotched (DBN) super wideband (SWB) printed monopole antenna (PMA) has been proposed. The proposed antenna composed of a circular PMA, which is connected through a 50-Ω triangular tapered microstrip fed line (TTMFL) and a round-cornered finite ground plane (RCFGP). It exhibits a very wide frequency band from 1.6-25 GHz (ratio bandwidth of 15.63:1) with a voltage standing wave ratio (VSWR)  2. By employing a U-shaped parasitic element (USPE) near the RCFGP and a T-shaped protruded stub (TSPS) inside the radiating patch, a single band-notched (SBN) characteristic in the frequency band of 3. is generated. In order to realize the second band-notched function for X-band satellite communication systems (7.2-8.4 GHz), a U-shaped slot (USS) has been inserted in the RCFGP. The overall dimension of the proposed antenna is 24  30  0.787 mm 3 and occupies a relatively small space compared to the existing DBN antennas. Good agreement has been attained between predicted and measured results.
