“…Circular monopoles [2] are the ideal model for UWB applications owing to advantages such as simplicity of production, satisfactory radiation characteristics, and huge impedance bandwidth. However, some applications such as those operating in the WLAN (5-6 GHz), WiMAX (3.3-3.6 GHz), and X-band satellite communication band (7.2-8.4 GHz) cause interference problems in the UWB frequency range.…”

Abstract-A MIMO/Diversity antenna with triple notch characteristics is proposed in this article. The proposed antenna has triple notches in the WiMAX band (3.3-3.6 GHz), WLAN band (5-6 GHz), and X-band satellite communication (7.2-8.4 GHz) band. Defected Ground Compact Electromagnetic Band Gap (DG-CEBG) is a design used to accomplish band notches. Defected ground planes are utilised so as to achieve compactness in conventional EBG structures. The proposed WiMAX band, WLAN band, and X-band satellite communication band DG-CEBG structures show a compactness of around 46%, 50%, and 48%, respectively, over a conventional EBG structure. In these structures, decoupling strips and a slotted ground plane are used to enhance the isolation between two closely spaced UWB monopoles. The individual monopoles are 90 • angularly separated with a stepped structure which helps to reduce mutual coupling and also contributes towards impedance matching by increasing the current path length. |S 21 | or mutual coupling is found to be less than 15 dB over the whole UWB frequency range. The Envelope Correlation Coefficient (≤ 0.5) is within the acceptable limits over the whole UWB frequency range. Notched frequency depends on the parameters of DG-CEBG structures; when there is a change in these parameters notch frequency is also changed. A low cost FR-4 substrate with thickness (h) = 1.6 mm, permittivity (ε) = 4.4 and loss tangent (δ) = 0.02 is used for the proposed antenna, and it has a compact size of 58 × 45 × 1.6 mm 3 .

ABSTRACT:In this paper, a printed, compact & ultrawideband (UWB) antenna used for three band notch characteristics are reported. Ultra-wideband (UWB) is one of the recent topics that received a great concern from academic and industry. However, UWB found many difficulties to be standardized due to the overlay working that made UWB an important potential interference source to many licensed and unlicensed spectrum throughout the band 3.1-to-10.6 GHz. In this paper we propose a compact ultra-wideband microstrip antenna with triple band notched 3.5 GHz, 4.9 GHz and 9.3 GHz. The proposed antenna consists of a curved patch with a partial ground plane that is fed by 50 Ω microstrip line. In this antenna notch filter achieved using small rectangular metallic strip with different size and positions. The notch frequency can be obtained by varying the length of rectangular metallic strip. Moreover, the proposed antenna provides good radiation patterns across the working bands and a relatively flat gain over the entire frequency band excluding the rejected bands.

“…Therefore, in order to meet the requirements, many researchers provide a large number of solutions. These solutions mainly include: a) ultra-wideband omni-directional antenna, of which wafer monopole antenna [1,2] is the representative, and various special-shaped-pole antennas [3][4][5], which are mainly used in the frequency band from 3.1 to 10.6 GHz (approved by FCC), but generally, this kind of antenna is omni-directional antenna with low gain, which could be arranged as an array to improve the gain, however, the feed network of the array is too difficult to solve; b) wide slot antennas [6,7], including all kinds of wide-slot coupled feed antennas whose gains are low; c) antennas with resistance gradual changing structure, including some ultra-wideband directional antennas, such as Vivaldi antenna [8], TEM horn antenna [9], ridged horn antenna [10], etc. However, most of these kinds of antennas are limited by their large volume for certain applications; d) frequency independent antennas, including equiangular and Archimedean spirals, log-periodic dipole antennas, and so on.…”

Abstract-A miniaturized printed log-periodic fractal dipole antenna is proposed. Tree fractal structure is introduced in an antenna design and evolves the traditional Euclidean log-periodic dipole array into the log-periodic second-iteration tree-dipole array (LPT 2 DA) for the first time. Main parameters and characteristics of the proposed antenna are discussed. A fabricated proof-of-concept prototype of the proposed antenna is etched on a FR4 substrate with a relative permittivity of 4.4 and volume of 490 mm × 245 mm × 1.5 mm. The impedance bandwidth (measured VSWR < 2) of the fabricated antenna with approximate 40% reduction of traditional log-periodic dipole antenna is from 0.37 to 3.55 GHz with a ratio of about 9.59 : 1. Both numerical and experimental results show that the proposed antenna has stable directional radiation patterns and apparently miniaturized effect, which are suitable for various ultra-wideband applications.
