Study of an Extremely Wideband Monopole Antenna With Triple Band-Notched Charactersistics

Abstract

Abstract-Three notched bands are generated, at selected frequencies, in an extremely wideband base antenna to support multiple communication systems while avoiding inference from other existing narrowband systems. The design of a fully printed extremely wideband antenna and creating triple band-notched functions are addressed in this paper. Measurements demonstrate that the proposed printed base antenna has an extremely wide 2 : 1 VSWR bandwidth from 0.72 GHz, to 25 GHz with a ratio bandwidth of 34 : 1. The antenna has a simple structure and can be fabricated at low cost for multi-band and wideband wireless communication devices. Besides, this paper presents a technique to form three notched bands within the operating frequency range of the base antenna. By introducing a half-wavelength U-shaped defected ground structure (DGS) and a pair of quarter-wavelength open arc-shaped slots to the radiating patch, three notched bands are created to prevent interference from WLAN (2.4-2.484 GHz and 5.15-5.85 GHz) systems and downlinks of X-band satellite communication (7.25-7.75 GHz) systems.

Broadband Modified Rectangular Microstrip Patch Antenna Using Stepped Cut at Four Corners Method

“…MPAs comprise narrow BW that is approximately 1-5%, which is the most major limiting factor for its widespread applications. Most of the previous contributions in this research area were to increase the BW of MPAs [1,2], and therefore, several measures have been introduced to achieve this objective, including modified shape patches, which is a method of modifying the shape of patch [3][4][5][6][7][8], utilization of slotted ground structure [9][10][11][12][13], modification of rectangular and circular patches to rectangular [14] and circular rings [15,16]. Another method includes an impedance matching network method proposed to enhance the MPAs BW [17][18][19].…”

Design of a Novel Super Wide Band Circular-Hexagonal Fractal Antenna

“…With an overall dimension of 30 mm × 29.1 mm, the designed antenna achieved to operate within 3-32 GHz. An extremely wideband monopole antenna with triple-band notched characteristics was presented in [20]. 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.…”

“…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.…”

“…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].…”

A 6.0 GHZ Small Printed Monopole Antenna for Wireless Implantable Body Area Network (Wiban) Applications

“…In order to operate as such systems, the antenna must be in small size and provide better performances than antenna operating in free space environments [6][7][8][9][10][11]. Based on the previously reported research works, printed monopole antenna has become a major field of interest due to its compact size, omni-directional radiation patterns, large bandwidth (BW) and high radiation efficiency [12][13][14][15][16][17][18][19][20]. The printed monopole antenna has therefore been chosen for WiBAN application, due to the aforementioned characteristics.…”
