“…It has already been reported that the utilization of band stop filter needs additional area to integrate which conclusively raises the complexity and cost of the design. Notch band characteristics have been found as the solution to avoid the interferences between UWB system and narrow band wireless system [23].…”

A microstrip antenna with a circular disc design and modified ground is proposed in this paper. Circular shapes of different size have been slotted out from the radiating patch for achieving extended ultra wideband (UWB) with GSM/Bluetooth bands with maximum bandwidth of 17.7 GHz (0.88-18.6 GHz). Further, characteristic of dual notch band is achieved, when a combination of T and L-shaped slots are etched into the circular disc and ground plane respectively. Change in length of slots is controlling the notch band characteristics. The proposed antenna has rejection bandwidth of 1.3-2.2 GHz (LTE band), 3.2-3.9 GHz (WiMAX band) and 5.2-6.1 GHz (WLAN band) respectively. It covers the frequency range of 0.88-18.5 GHz with the VSWR of less than 2. Also, an equivalent parallel resonant circuit has been demonstrated for band notched frequencies of the designed antenna. The gain achieved by the proposed antenna is 6.27 dBi. This antenna has been designed, investigated and fabricated for GSM, Bluetooth, UWB, X and Ku band applications. The stable gain including H & E-plane radiation pattern with good directivity and omnidirectional behavior is achieved by the proposed antenna. Measured bandwidths are 0.5 GHz, 0.8 GHz, 1.1 GHz and 11.7 GHz respectively.

“…12 Additionally, various other methods have been employed to introduce dual band-stop characteristics for rejecting the interference in the UWB antennas. [13][14][15][16][17][18][19][20] However, most of the designs have large footprints and average performances (in terms of peak gain, radiation pattern, etc. ).…”

This article introduces a novel and compact design of an ultra‐wideband (UWB) printed monopole antenna with an enhanced bandwidth and dual band‐stop performance. A modified π‐shaped slot has been inserted in the ground plane to exhibit a wide impedance bandwidth of 116% (ranging from 3.1 to 11.2 GHz), whereas dual stopband responses (at 3.5 and 5.5 GHz) are obtained by embedding three I‐shaped stubs and a pair of modified Γ‐shaped slits in the radiating patch. The proposed topology is highly compact having an overall dimension of 18 mm × 14 mm (which is equivalent to 0.7λg × 0.54λg, where λg is the guided wavelength corresponding to the lower resonance band), has a low fabrication cost, an ultra‐wide impedance bandwidth, and omnidirectional radiation patterns in the H‐plane, which make the antenna appropriate for wideband applications and integration into UWB system. To check the advantages of the proposed antenna, experimental verification has been carried out as well as the results are compared for UWB scenarios.

“…The design of a MIMO radiation configuration faces challenges such as achieving a higher isolation between the interradiating elements. Two reported research papers [1,2] used fractal flower-shaped geometry where two different substrates were used in the design (FR4 and Rogers RTDuroid5880); both covered the UWB bandwidth for different specific applications when compared with the proposed work. The proposed work was designed for a MIMO configuration for encountering fading of the signals.…”

This research article reports a compact fractal 4 × 4 UWB extended bandwidth MIMO antenna with physical dimensions of 44 × 44 mm2 for high-speed wireless applications. The reported antenna comprises four fractal radiating elements that are symmetrical and placed orthogonal to each other with a respective rectangular ground printed on the opposite plane. A higher isolation is achieved between the radiating elements by the placement of a fractal patch orthogonally and no separate decoupling structure is required. The antenna offers a −10 dB transmission capacity of 2.84–15.88 GHz. The fractal radiating element, which is embedded by an inverted T-type stub placed within a rectangular slot and an etched rotated C-type slot, provides band-stop filters for WiMAX (Worldwide inter-operability for Microwave Access) and WLAN (wireless local area network)-interfering bands. The key parameters of diversity performance are compared by simulation and measurement (fabricated prototype) of ECC (envelope correlation coefficient), DG (directive gain), TARC (total active reflection coefficient) and CCL (channel capacity loss). The antenna offers an omnidirectional radiation pattern with an average gain of 3.52 dBi.
