“…In [4], a planar holographic leaky-wave antenna capable of generating four beams simultaneously is designed. In [5], a 3-D printed wideband Cassegrain antenna for linear multi-beam is proposed. By stacking five Cassegrain subarrays with different tilt angles, 2-D multi-beam radiation can be realized.…”

“…In this paper, a beam-changeable concentric annular LWA array is proposed. Comparing to the multi-beam antennas in [1][2][3][4][5][6][7][8]16,17] which mostly provides only directive switchable beams, this work generates multi-beams including directive beam, omnidirectional beam and synthetic beam. This adapts to more coverage demands.…”

“…Generally, there are three types of beam-forming network (BFN) in scanning beam antenna design that are lens, reflector and planar BFNs. [2][3][4][5] The Rotman lens is composed of a focal curve, an array curve and delay lines. It is attractive because of its simple design, compact size, and flexibility in the layout dealing with numerous ports.…”

A 7 Â 8 Butler matrix (BM) beam-forming network operating at Ka-band is proposed to feed a 8 Â 8 slot array. By merging the two central input ports of the BM into one port, the BM can provide output signals with equal phase, thereby generating a boresight beam. Measured results show that the proposed antenna has impedance bandwidth of 29.5-30.5 GHz, while the gain lies in the range of 14.7-21.8 dBi. Seven beams are realized, including a boresight beam, covering the range from À58 to 58 . In order to verify this concept, the feeding network and antenna are designed and manufactured. The measured results are in good agreement with simulation. It is a capable candidate for 5G mobile terminal applications.

“…Recently, the remarkable success of newly emerged 3D printing technology offered an effective platform for increased geometrical and material versatility [17]. Notable 3D printed antenna design examples have been implemented [18][19][20], showing that both a high radiation performance and a low fabrication cost can be simultaneously fulfilled. A 3D printed metallic Cassegrain antenna with a concave reflector [18] is presented for operation in the Ka-band.…”

High Gain SIW H-Plane Horn Antenna with 3D Printed Parasitic E-Plane Horn

et al. 2021

Substrate integrated waveguide (SIW) technology that combines 3D and 2D structures has been successfully utilized due to its notable advantages, including in its application to H-plane horn antennas. As this type of antenna is commonly constructed on thin substrates, the E-plane radiation pattern is always wide, thereby limiting the achievable gain performance. In this work, we propose an approach that incorporates 3D printed horns on a prefabricated SIW H-plane horn antenna to successfully narrow the E-plane radiation pattern, thereby improving the gain performance. The proposed E-plane horn is designed at the aperture of the original H-plane horn, providing a smooth and continuous wave transition from the thin substrate to the end-fire direction. This approach improves the directional radiation performance significantly and reduces fabrication time and associated difficulties as the parasitic structures are simply attached to the SIW horn, without the requirement of redesigning or refabricating the original antenna. From 20 to 25 GHz, an optimized prototype shows excellent performance. At 22.7 GHz, it exhibits 35° and 33° for the E- and H-plane half-power beamwidths (HPBWs), with corresponding side-lobe levels (SLLs) of −23 dB and −15 dB. The present research reveals that the proposed design presents high feasibility and a reduced demand for high-precision manufacturing processes at a lower cost, concomitantly providing an effective means to further improve on the radiation characteristics.
