“…The simulated radiation efficiency is better than 90% in the operating band and the measured efficiency is better than 80%. The measured efficiency is calculated using the measured gain and simulated directivity . The differences in the efficiency may be due to fabrication tolerance, ground plane roughness, dielectric loss tolerances, and so on.…”

“…In Ref. , a centered‐off coaxial probe fed substrate integrated waveguide (SIW) cavity backed annular ring slot antenna has been proposed for multiband multimode application. The radiation pattern for this structure is similar to that of a monopole having bandwidth of 4.5% and gain of 4.8 dBi in one of the bands (at 7.8 GHz).…”

In this article, a substrate‐truncated microstrip circular patch antenna with shorting vias is proposed for X‐band applications. The bandwidth of the designed antenna is substantially increased by making two slots—one circular and another annular ring—at the top of the structure which actually helps in bringing two individual resonating frequencies closer to each other. The antenna is simulated using the Ansoft HFSS, and various parameters are optimized for better performance. The deigned structure is finally fabricated and tested, and the measured data fairly agree with the simulated results. The measured relative impedance bandwidth (|S11| < −10 dB) is found to be 28.5% (8.9‐11.85 GHz). The proposed antenna is behaving like a monopole with the radiated beam of conical shaped in the entire operating band having a maximum gain of 7.2 dBi.

“…These antennas have disadvantages of two inputs connectors, low gain, and multi-layer of substrates. The annular ring patch antenna proposed in [15] worked at multibands and multi-modes, with tuning all design parameters. However, there are few Terahertz antennas which can realize multiband and dual-mode characteristics simultaneously with a high gain for imagery application and Terahertz telecommunications.…”

This paper presents a multi-band annular ring antenna that is obtained from a singlelayer probe-fed substrate integrated waveguide based on a graphene material, with three top plan slits. In order to create a multi-bands antenna, we conduct simulation of the antenna structure based on CST/HFSS, so we use parametric tuning to adjust TM modes. Simulations show a good results between the two methods (finite element method and integral method) CST and HFSS Simulators. The bandwidths for three modes are 340 GHz in first mode, 346 GHz in the second mode, and 104 GHz in the third mode. The simulation gains at T M 11 , T M 02 , and T M 12 are 8.2 dB, 8 dB, and 11 dB, respectively. The proposed antenna can be used in therahertz applications.

A low-profile triple-band, dual-mode and dual-polarization antenna is proposed in this paper. An annular interdigital slot etched on the top conductor layer of the antenna is employed as a radiator. Through adjusting the location of coaxial probe, three operating modes TM 11 , TM 02 , and TM 12 of the antenna are excited simultaneously. Two patch-like radiation patterns and one monopolar radiation pattern at three different frequencies are obtained. In addition, circularly polarized (CP) property for TM 11 and TM 12 modes is achieved by employing a 45 • inclined rectangular slot at the center of the antenna. To validate the properties, a prototype is fabricated and measured. The results illustrate that this antenna is attractive in wireless communication systems for its simple structure and multifunction.
