“…The modifications incorporated in the configuration-II improved the radiation performance at 5.8 GHz, when compared with the radiation characteristics obtained in Ref. 13. This improvement in the radiation pattern is due to reduction in the contribution of undesired higher order mode excited inside DRA-1 due to loading effect from the DRA-2, at the desired operating frequency.…”

“…The coaxial probe is placed touching at the center of one of the sides This configuration in its basic form reported in Ref. 13, has a significant contribution of higher order TM 3-3δ mode excited (in DRA-1) in the upper operating band, which effects the desired radiation characteristics. However, these effects are significantly reduced by redesigning it to configuration-II, so that, a similar radiation characteristic is maintained in both the operating bands.…”

“…The objective of this design is to maintain similar radiation characteristics at both the operating frequencies, using a simple excitation mechanism. A preliminary investigation of this design configuration using full wave EM (Electromagnetic) simulation is reported in our earlier work, 13 where RT/Duroid6010 material was used for the antenna elements. However, for the design reported in Ref.…”

In this article, two configurations of dual-band equilateral triangular dielectric resonator antennas (ETDRAs) for WLAN applications are proposed namely, configuration-I and configuration-II. The configuration-I uses single ETDRA for dual-band operation; whereas, configuration-II includes two ETDRAs to operate as a dual-band antenna. Both the antenna configurations, which uses 99.7% alumina material having a dielectric constant of ε r = 9.9, are excited to operate in the bands of 2.4 to 2.5 GHz and 5.75 to 5.85 GHz. The antennas are excited using a conventional coaxial feed to have a simple feeding mechanism.Prototypes of both the antenna configurations are fabricated and measured. The radiation characteristics of the antennas are discussed. The circuit analysis for the proposed configurations of the dual-band ETDRA is also performed and an appropriate equivalent circuit for each dual-band ETDRA is presented.Further, the performance of the proposed configurations of the dual-band antennas are also compared with other dual-band DRAs reported in the literature.

“…From Figure , it is clearly perceived that optimum impedance bandwidth is obtained at point D. The resonance at 2.45 GHz is due to

{TM}_{101}^{z}

mode pattern inside the triangular DRA, which is clearly observed from E‐field distribution in Figure . The resonance due to

{TM}_{101}^{z}

mode is obtained from waveguide model transcendental equation:

f_{r} = \frac{c}{2 π \sqrt ε_{r}} \sqrt{((), \frac{4 π}{3 a}) ((), m^{2} + italicmn + n^{2}) + k_{z}^{2}}

This article concentrates on the design and analysis of a novel Minkowski fractal‐based antenna design with the aid of triangular dielectric resonator (TDR) elements for wideband wireless applications. TM101z mode is excited inside equilateral TDR antenna with the help of coaxial probe feed. Wide impedance bandwidth has been achieved by reducing the quality factor with the help of increasing surface area‐to‐volume ratio of radiating structure. Another important feature of this article is that recurrence formulas are derived to calculate the fraction of surface area to volume of proposed fractal antenna up to nth iteration. The proposed antenna design is fabricated and measured up to third iteration to verify its simulated outcomes. Practically measured outcome confirms that the proposed antenna design operates over the frequency range, that is, 2.23‐3.1 GHz with the maximum gain of 3.62 dBi. These features make it appropriate for wireless LAN (2.4 GHz) and WiMAX (2.5 GHz) applications.

Nowadays, we are witnessing a considerable change in the field of telecommunications, be it mobile telephony, wired or wireless networks. Advances in the fields of information technology, communication, microelectronics and telecommunications have led to a massive deployment of new networks which today connect a mass of individuals and computing entities. These networks are the backbone of all services influencing both the personal and professional spheres, with almost instant access to information, social networks and the IT world. In this regard, the antennas deployed in new telecommunications systems must be able to adapt to such an environment in perpetual evolution. Indeed, with the emergence of new telecommunications standards such as the Internet of Things (IoT), new telecommunications systems must meet new requirements, including the ability to include a large number of features to meet to the growing needs of users, such as making several standards coexist on the same compact structure, reducing interference with neighboring devices, improving the transmission rate, avoiding phenomena of antenna performance degradation in the presence of external disturbance and ensuring good efficiency in receiving data. Agile antennas in radiation patterns also present themselves as potential candidates to meet the requirements imposed.
