“…This is because SIW antennas and RF components are very easy to design and integrate at these frequencies due to their compact size. Also, they are suitable for array design for beam-scanning and other beam-forming systems in PCBs, without requiring a complex feeding network [1]- [4].…”

A novel reconfigurable slotted leaky-wave antenna (LWA) based on a substrate integrated waveguide (SIW) with a fixed-frequency beam-steering capability is presented in this paper. For improved compactness, the structure is based on a SIW technology with rectangular slots fed by associated coupling with plated-through holes (PTH).This represents a new feeding method for etched slots in SIW antennas. Each via is loaded with a pin diode on both sides frontend of the waveguide. The pin diodes are tunable by adjusting the DC bias voltage, which results in beam scanning at a fixed frequency of around 27 GHz. Thus an electronically controlled steerable SIW antenna has been designed and experimentally verified that the radiation angle varies from −33 • to +33 • .

“…The design process begins with the choice of the polarisation mechanism. Rather than using multiple elements of orthogonal polarisations (such as in [15,19,20]), the single antenna element will incorporate the polarisation mechanism within it (similar to [21]), thus making the structure compact. Specifically, it is a SIW notched-septum polariser.…”

This study presents a circularly‐polarised substrate‐integrated waveguide end‐fire antenna and four‐antenna arrays for 5G beam‐steering mobile devices at 28 GHz. Polarisation is achieved through implementation of a substrate‐integrated waveguide notched‐septum polariser. It is then loaded with a dielectric lens to improve gain, axial ratio bandwidth, and circular polarisation (CP) purity. To suppress the mutual coupling between array elements, vias are extended on either side of the lens. It also improves the single‐element axial ratio and front‐to‐back ratio. The antenna's performance is found to be resilient to typical manufacturing tolerances for the lens and via extensions. The element and arrays are manufactured and measured. The prototypes demonstrated an impedance bandwidth of 11.4% with a maximum array gain of 10.5 dBi and a steering range of up to ±35° (with reduced performance when steered to ±45°). Within this range, the antenna array demonstrates a gain variation of up to 3 dB and very good CP purity within the radiation half‐power beamwidths (HPBWs). A wide single‐element elevation HPBW of 95° is also demonstrated. Given its performance and ease of manufacture in a printed circuit board process, the proposed antenna could be a strong candidate for 5G millimetre‐wave beam‐steering systems.

“…Recently, substrate integrated waveguide (SIW) antennas play an important role in communications due to their light weight, low profile and easy integration with other planar circuits 1‐6 . However, most of SIW antennas have an inherent drawback of narrow bandwidth due to high quality factors of cavity modes 7 …”

A ferrite‐loaded four‐petal‐shaped antenna with enhanced bandwidth is designed and fabricated. There are two layers in the antenna. A substrate integrated waveguide cavity is formed by a circular metallized via array on the lower substrate of the antenna. As a broadband radiating element, a four‐petal‐shaped radiation unit is etched on the bottom surface of the circular SIW cavity. By loading low‐loss ferrite discs with relatively high dielectric constant in the upper substrate layer as dielectric resonators, a relatively smaller broadband cross‐dipole antenna is realized. The measured results demonstrate that the working frequency band of the antenna is 1.83 to 3.53 GHz (63.4%) if the S11 is less than ‐10 dB. The antenna with the size of 0.29λmax × 0.29λmax has stable bidirectional radiation patterns with the average realized gain and radiation efficiency of 4.14 dBi and 94% in the working frequency range. Due to the characteristics of low cost, low profile, easy integration with planar circuit, the proposed antenna is suitable for wireless communication applications, such as CDMA, 4G, 5G, IMT‐2000, WiMAX, WiFi, and Bluetooth.
