“…In recent years, there has been an increasing amount of literature on SWB antenna [13][14][15][16][17][18][19][20][21]. For example a compact semi-elliptical patch antenna fed by a tapered coplanar waveguide was designed in [13].…”

“…With a size of 150 mm × 150 mm, the designed antenna achieved a bandwidth ranging from 0.72-25 GHz with three notch band for WLAN and X-band. In [21], a monopole antenna with super-wideband was proposed. However, it's three dimensional structure makes it difficult to be integrated into portable devices.…”

“…However, it's three dimensional structure makes it difficult to be integrated into portable devices. Besides, the antennas proposed in [19][20][21] do not cover K-band which opens a new arena to design antenna that covers S, C, X, Ku, K and Ka bands.…”

Abstract-In this paper, a novel circular-hexagonal Fractal antenna is investigated for super wide band applications. The proposed antenna is made of iterations of a hexagonal slot inside a circular metallic patch with a transmission line. A partial ground plane and asymmetrical patch toward the substrate are used for designing the antenna to achieve a super wide bandwidth ranging from 2.18 GHz to 44.5 GHz with a bandwidth ratio of 20.4 : 1. The impedance bandwidth and gain of the proposed antenna are much better than the recently reported super wideband antennas which make it appropriate for many wireless communications systems such as ISM, Wi-Fi, GPS, Bluetooth, WLAN and UWB. Details of the proposed antenna design are presented and discussed.

“…SWB antennas have received much attention in military and civilian systems because their broadband characteristics can provide high data-rate services [2]. For this reason, several 2D and 3D SWB antennas have been introduced [3][4][5][6][7]. The modified star-triangular fractal monopole antenna introduced by Waladi et al [3] and the asymmetric coplanar strip fed hexagonal loop antenna from Trinh-Van et al [4] have 2D geometries and compact sizes, meeting the −10 dB reflection ratio bandwidth requirement of 30:1 or greater.…”

Abstract:In this paper, a 3D-printed super-wideband (SWB) Spidron fractal cube antenna is proposed. The Spidron fractal configuration is utilized as a self-complementary structure on each face of a 3D frame to attain SWB characteristics. The antenna is excited through a tapered microstrip balun for both mode transforming and impedance matching. A prototype of the proposed antenna, including the 3D frame fabricated with the help of a 3D printer and Spidron fractal patches made of copper tape, is experimentally verified. The measured −10 dB reflection ratio bandwidth is 34:1 (0.44-15.38 GHz). The peak gain varies from 3.42 to 9.29 dBi within the operating frequency bandwidth. The measured radiation patterns are nearly omnidirectional at all operating frequency bands.

“…Several useful techniques are used for the bandwidth enhancement of the monopolar patch antennas in [3][4][5][6][7][8][9][10][11]. The height of these antennas is about 0.1λ 0 (or even higher), which is too large for some applications such as conformal radiator.…”

Abstract-A microstrip monopolar patch antenna with shorting vias in the circular patch and coupled ring for bandwidth enhancement is proposed. The bandwidth of the proposed antenna with shorting vias in the annular coupled ring is over 40% wider than that of the antenna without shorting vias in the annular ring. The proposed antenna provides a wide bandwidth because of four resonant modes, including the TM 01 mode of the circular patch, TM 01 mode of the coupled annular ring, TM 02 mode of the circular patch, TM 02 mode of the coupled annular ring. These modes can generate an omnidirectional pattern in the azimuth plane like a monopole antenna. A prototype was fabricated to confirm the simulation verdictions. Measured results show that 10-dB return loss bandwidth of 38.4% from 4.42 to 6.52 and average gain of 5 dBi acrossing the operating band are achieved for the proposed antenna with a low profile of 0.027 wavelength.
