“…In, a biconical antenna for ultrawideband applications is designed, by adding several different geometric features that reduce the size of the antenna and expanding the frequency band from 3.1 to 10.6 GHz. In, a vivaldi antenna is illustrated, by using dielectric load with printed metal transition and transverse ripples and fed by the substrate integrated waveguide, which overcomes shortcomings of conventional antipodal vivaldi antenna and obtains a wide frequency band from 24 to 50 GHz. Unfortunately, the introduced antenna in both have a large size, which limits its application in portable devices.…”

that of the nonself-aligned RTD. The calculated f C of the self-aligned RTD is increased by about 13.6% compared with that of the nonself-aligned RTD. The results show that the fabricated self-aligned RTD with the SiN X sidewall process improves the RF performance by reducing the spacing (d) resulting in lower R S due to reduced R SEMI . By using a scaled-down device technology with an electron beam lithography, the high-speed characteristics of the self-aligned RTDs will be improved. | C ONCL US I ONA self-aligned RTD using a SiN x sidewall process has been fabricated and characterized. The dry etching process has been developed for the self-aligned RTD with 5 lm 2 emitter size to obtain the highly anisotropic mesa profile. The fabricated RTD showed the PVCR of 13.1 with a peak voltage (V P ) of 0.348 V. The measured peak currents and peak voltages were almost constant in the temperature range between 25 and 1258C. The self-aligned RTD showed the R S reduction of 27% compared with the nonself-aligned RTD by reducing the spacing between emitter mesa and collector metal. The results achieved in this work indicate that the self-aligned RTD with the SiN X sidewall will offer a viable option for the future high-speed microwave applications. ORCIDKiwon Lee http://orcid.org/ AbstractIn this work, a novel very wideband 4-element monopole based multiple-input multiple-output (MIMO) antenna system with single connected antenna array (CAA) is presented. The CAA is based on a single slot which is etched on the ground plane. A 2 3 1 power divider/ combiner is used to excite the slot to act as a CAA. The

“…However, on account of its thin open end, it has narrow operating band [2]. The Vivaldi antenna also has characteristic of broadband, but the cross-polarization and side lobes will deteriorate rapidly as the operating frequency increases [3]. The quasi-Yagi antenna, a typical type of parasitic element antenna, has lots of advantages, such as simple…”

Design of Dual-/Wide-Band Quasi-Yagi Antenna Based on a Dielectric Resonator

This paper presents a design approach of dual-/wide-band quasi-Yagi antenna using a dielectric resonator (DR). A single rectangular DR operating at TE 1δ1 and TE 1δ3 modes can be differentially fed by the coplanar strip line (CPS) and then is used as a driver, which functions as a dual-mode magnetic dipole (M-dipole) resulting from the TE 1δ1 and TE 1δ3 modes. Thus, a dual-band quasi-Yagi antenna with two close operation frequencies can be designed, meanwhile, the two bands can be independently controlled. Based on this, a wide-band quasi-Yagi antenna is introduced by adding two metal directors with different sizes on the top and bottom layers of the supporting substrate. The two directors provide two additional resonant frequencies, turning dual-band antenna into a wide-band one. To verify the design concepts, two prototypes of dual-and wide-band antennas are fabricated and measured. Good agreement between the simulated and measured results can be observed. The wide-band antenna has a measured-10 dB impedance bandwidth of 21.7 % (9.33-11.6 GHz). Within it, the peak gain of antenna is 8 dBi and 1 dB gain bandwidth is 15.5%. INDEX TERMS Quasi-Yagi antenna, dielectric resonator (DR), M-dipole, dual-band, wide-band, high gain.

“…There has been previous research published on Vivaldi-shaped antennas which are often also using a SIW feeding structure. The main difference to our work is that those antennas are mostly operating at a significant lower frequency band [11][12][13][14][15]. Therefore, the published approaches had less challenging requirements regarding substrate material and fabrication tolerances and process.…”

This paper describes the design and characterization of a compact substrate integrated waveguide (SIW) fed antenna for the 122 GHz industrial, scientific, and medical band. The use of a single RO4350B substrate layer and the SIW feeding ensure a low-cost fabrication. Two versions of the antenna are presented differing in antenna gain and size. For measurement purpose, a transition from rectangular waveguide to SIW is introduced. Measurements of the radiation pattern have been performed and show good agreement with the numerical results for both antennas and an antenna gain up to 7.14 dBi.
