“…Multiple designs have been proposed based on MEdipoles or dielectric resonators at mm-wave bands in the literature. Several articles have introduced MEdipole to cover wideband operation around 30 GHz based on printed ridge gap waveguide, packaged microstrip line, and substrate integrated gap waveguide technologies [19], [21], [23]. The bandwidth of such designs is around 20% with a gain in the range of 5 to 8 dB with large variation over the operating bandwidth.Other designs enhanced both the gain and the bandwidth through loading the ME-dipole with Split Ring Resonators (SRR) or PMC surfaces [8], [20], [22], [24].…”

Future communication standards have an increasing interest in Millimeter Wave (mm-wave) bands, where wide bandwidth and secured communication can be assured. This trend in communication standards stimulates the research community to provide novel antenna configurations in the mm-wave bands. This article proposes a novel design and analysis of hybrid magneto-electric dielectric-resonator dipole antenna that features an electrically small size with ultra-wideband operation and consistent radiation characteristics in the mm-wave band. The proposed antenna is designed based on the combination of multi-resonances produced by a Magneto-Electric (ME) dipole and stacked Dielectric Resonator Antennas (DRAs). In addition, the proposed antenna is implemented using state-of-the-art Printed Circuit Board (PCB) technology, namely, Printed Ridge Gap Waveguide (PRGW) for low loss and cost-efficiency. The combination between the ME-diple and stacked DRA is adopted to ensure symmetric radiation characteristics in both E-and H-planes over ultra-wideband operation with a deep matching level. Both DRA and ME-dipole elements are designed and studied separately, where a systematic design procedure is presented to obtain initial design parameters. Proper integration between the radiating elements introduced an electrically small size antenna (0.64 λ ×0.48λ ) covers the full Ka-band (26-40 GHz) with a matching level beyond -20 dB and gain stability of 8±1 dB. The antenna prototype is fabricated, where a good agreement is shown between both simulated and measured results.

In this article, an integrated substrate groove gap waveguide (Integrated‐SGGW) is proposed, which is composed of gap and groove layer in printed circuit board technology, which is considered a highly integrated circuit design technology. Electromagnetic wave is transmitted via the dielectric groove in transverse electric mode. Firstly, the waveguide is analyzed, including dispersion characteristics, transmission characteristics, characteristic impedance and field distribution. Then, the theory of dispersion and characteristic impedance for the Integrated‐SGGW are given, and the waveguide is comprehensively analyzed. An Integrated‐SGGW is fabricated, verified, and compared with substrate integrated waveguide and other waveguides. To show Integrated‐SGGW applications in the design of millimeter wave circuits, a third‐order bandpass filter using the Integrated‐SGGW is designed, fabricated, and verified.

“…The second technique is to use a substrate with high permittivity. 17,18 In Reference 17, a ME dipole antenna is designed in Substrate-Integrated-Gap-Waveguide and is able to realize a low profile of 0.19λ 0 . In Reference 18, by introducing a defected ground structure, the thickness of the ME dipole is decreased to 0.082λ 0 while the impedance bandwidth is only 14.7% for voltage standing wave ratio (VSWR) < 2.…”

In this article, a multilayered substrate-integrated magnetoelectric dipole antenna with low profile and wideband is proposed. Based on the multilayered printed circuit board technology, the magnetoelectric dipole antenna is composed of four layers of substrate. By adopting rectangular window techniques, the impedance matching at the low-frequency band is improved and a low profile of 0.08λ 0 (where λ 0 is the free space wavelength of the center frequency) in height is achieved. A Γ-shaped meandering unit is also adopted to guide the electric current through the rectangular window and enhance the boresight radiation. Additionally, the antenna is fed by a 1/4 wavelength microstrip line on bottom plane to easily integrate to the front-side planar circuit. The transverse size of the proposed antenna is 100 mm*50 mm (0.8λ 0 *0.4λ 0 ). Through simulation and optimization, the wideband, low profile, and unidirectional radiation characteristics are obtained simultaneously. The tested impedance bandwidth ranges from 1.92 to 3.15 GHz (48.5%) for voltage standing wave ratio (VSWR) < 2. The radiation property is also validated and the boresight mean gain is 5.1 dBi. Cross polarization level at boresight is lower than À25.15 dB. Both simulated and tested results agree well with each other.
