“…In this letter, the H‐plane horn antenna based on the rectangular sheet loading SIW technology is selected as the feed of the CTS array, which reduces the undesired reflection and overflow loss of the lower parallel plate edge, as shown in Figure . The loading form is used on the flare side to increase the horn matching bandwidth and gain. According to the requirements of the pillbox beamformer, the horn antenna unit of adjacent feeding positions has a distance of 1.5 λ d , the feeding horn surface is 10 mm, and the operating frequency is 29 GHz.…”

A hybrid structure continuous transverse stub (CTS) array antenna for Ka‐band is demonstrated in this article. The array comprises 16 radiating slots, the H‐plane horn antenna based on the substrate integrated waveguide (SIW) and is fed by a corporate‐feed network in parallel plate waveguide (PPW) technology. The scanning angle of the main beam of the antenna reaches ±40° through switching the horn feed. Measurement shows that the CTS antenna has an relative bandwidth of 17.2% from 26.5 to 31.5 GHz for the standards of |S11| < −10 dB. At the center frequency of 29 GHz, the antenna gain of 28 dBi is obtained, the H‐plane sidelobe level (SLL) is −28.5 dB, and the radiation efficiency reaches 90%. The measurements are in very good agreement with full‐wave simulation results. The proposed design is suitable for Satcom Ka‐band terminals in moving platforms, for example, ships and planes.

A broadband substrate‐integrated waveguide (SIW)‐fed endfire metasurface antenna array with improved gain centralisation radiation pattern is proposed in this paper. The metasurface is composed of 3 × 3 rectangular patches distributed on both the upper and lower sides of a single‐layer substrate. For wideband endfire radiation, an open‐end SIW on the metasurface side feeds the antenna. To improve front to back radiation and ration matching characteristics, one C‐shaped slot is etched on the top surface of SIW. Two L‐shaped metal walls composed of metalized via holes are employed to centralize radiation pattern and reduce both the side lobe and back lobe levels. In addition, the gain of the antenna is enhanced more than 1.6 dBi. To validate this design, a 1 × 8 uniform excitation array is proposed and fabricated, containing three SIW T junctions and four Y junctions. The whole dimension is 7.33λ0× 3.82λ0 × 0.06λ0. Measurement results imply that an 7.5 to 13.05 GHz (54%) impedance bandwidth can be achieved with the maximum gain of 14.9 dBi.

“…A similar approach to correct the phase front is used in [29] but, the apertures are loaded with antipodal linearly tapered slot antennas and they are stacked in order to carry out a monopulse antenna. Alternatively, the work in [30] achieves the correction of the phase front by using longitudinal gaps in the upper and lower copper layers and along the H-plane horn antenna. Additionally, a transition between the substrate and the air at the antenna aperture is implemented in order to increase the gain of the antenna.…”

Modular Design for a Stacked SIW Antenna Array at Ka-Band

et al. 2020

This paper presents a modular substrate-integrated waveguide (SIW) antenna array based on H-plane aperture structures for Ka-band. The unitary antenna is based on a SIW aperture antenna with an improved H-plane radiation pattern by means of the implementation of metallic vias in the wave propagation along the H-plane antenna. The inner metallic vias are introduced to form four different sub-apertures at the end of the H-plane aperture antenna, dividing the field from the feeding into four in-phase wavefronts. In that manner, a flatter wavefront is generated to achieve high directivity. Additionally, some periodic parallel strips are printed at the end of the antenna aperture to improve the impedance matching with the air. The Hplane antenna is used as the constituting element for an E-plane array antenna, using four H-plane elements. The E-plane array antenna increases the antenna directivity, providing a pencil-shape beam, based on a series coaxial feeding structure. This feeding strategy favours the antenna modularity at the expense of suffering from a slight beam steering with frequency in the working bandwidth. The proposed antenna has an impedance matching below-10 dB from 32.9 to 37.0 GHz (equivalent to 11.73% bandwidth) with a nearly stable gain of almost 10 dBi for the H-plane unitary element and 14 dBi for the E-plane array. Prototypes of both antennas are manufactured to validate the proposed unitary antenna and array designs.
