“…There are many research topics on bidirectional antennas such as [12][13][14][15][16] that extensively used various ring shapes (i.e., waveguide sections with moderate widths) such as rectangular, circular, and elliptical rings, to force the radiating beams in two opposite directions. Some other techniques are also introduced such as collinear antennas with parasitic wire elements in [17,18] and a fractal patch antenna with pattern reconfigurable capability in [19].…”

This paper presents the design of a dual-band bidirectional ring antenna fed by a superellipse surface probe for 2.4/5 GHz WLAN applications. The Method of Moments (MoM) with RWG basis function was utilized in the study and design processes. A prototype antenna was fabricated successfully with the advantages of simple and low-cost structure. The measured impedance bandwidth of 810 MHz (2.10–2.91 GHz) and 2.39 GHz (3.57–5.96 GHz) is achieved for the first and second band, respectively. The peak gains are also feasible, 4.67 dBi at 2.45 GHz and 7.83 dBi at 5.5 GHz, with bidirectional radiation patterns for both bands. From the experimental field tests, the proposed antenna was suitable for most applications in long and narrow communication sites in 2.4/5 GHz bands as desired. Also, the measured and calculated results were in good agreement.

“…Therefore, for a base station antenna, a bidirectional antenna is more suitable for the street cell than a typical omnidirectional antenna. Thus, many researches and developments on bidirectional antenna have been extensively conducted as reviewed in literature [6][7][8][9][10][11]. From the aforementioned researches, it is evident that development of a bidirectional antenna that has suitable characteristics for a particular application is desired.…”

Abstract-Radiation characteristics of a probe-excited rectangular ring antenna are investigated by using the dyadic Green's function approach. The radiation characteristics, such as radiation pattern, beam-peak direction, half-power beamwidth and directivity, are analyzed. For the specified operating frequency, the ring width and ring height are selected as the same cross-sectional dimension of rectangular waveguide operated at the dominant mode. The effects of the excited probe and rectangular ring to the modal distributions are described. For the desired modal distribution, the directivity primarily depends on the ring lengths. For compact size of the proposed antenna, the ring length of 0.4λ is chosen to provide a bidirectional pattern with the calculated half-power beamwidth in E-plane and H-plane of 100 and 69 degrees respectively, and directivity of 4.43 dBi. Furthermore, the prototype antenna was fabricated and measured. The coincided results between the theory and the experiment are obtained.

“…In addition, bidirectional antennas can be enlarged the cell size along the street in microcell environment [1,2]. Therefore, many researches and developments on bidirectional antennas have been extensively conducted [3][4][5][6][7][8][9][10]. Nevertheless, the low cost must be considered since the number of cell is very large.…”

Radiation pattern, impedance characteristics, and gain of a probe-excited rectangular ring antenna are investigated by the Method of Moments with the Rao-Wilton-Glisson (RWG-MoM) basis functions. The analysis is carried out for different lengths and positions of the probe as well as various lengths, widths and heights of the ring. In addition, the distribution of the surface current is also illustrated. Consequently, the suitable parameters are determined. It is obvious that the proposed antenna offers a bidirectional pattern with the impedance bandwith (|S 11 | < −10 dB) of 17%. Along the direction of the ring aperture, the gain is 5.28 dBi. Furthermore, the prototype antenna was fabricated and measured to verify the validity of the numerical calculation. It is found that the numerical and measured results are reasonably in good agreement.Corresponding author: S. Lamultree (suthasineel@asianust.ac.th).
