“…For the SIW based dual-beam LWA, a few works can be found. In [20], a dual-beam SIW LWA is proposed based on the orthogonal excitation of TE 10 and TE 01 modes which radiate through the top wall and lateral wall of waveguide respectively, so two radiation beams are generated. However, the two beams of this antenna cannot scan and the gain difference between them is more than 3 dB.…”

A novel fixed-frequency beam switchable dual-beam antenna array is presented, which consists five dual-beam leaky-wave antenna (LWA) elements designed on substrate integrated waveguide (SIW) and integrated together on a common substrate. The LWAs work on fundamental wave and-1th spatial harmonic wave simultaneously and excite two symmetrical radiation beams in forward and backward direction respectively. In order to realize beam switching, three voltage-driven radio frequency chip switches (CSW-RFs) are used and integrated behind the antenna aperture. Since the periodic slot in LWA causes open stopband at the operating frequency, so the staggered radius amplification of local vias in the via walls of SIW is performed to suppress the open stopband. In addition, electromagnetic band-gap (EBG) structures, capable of reducing coupling between neighboring antenna elements, are embedded in between LWAs. The proposed dual-beam antenna array with beam switching capability between ±35, ±45, ±55, ±65 and ±75 degrees at 28 GHz are simulated, fabricated and measured. Both analysis and measurement results show that the proposed antenna array exhibits an excellent performance, which can be used in fixed-frequency beamswitching millimeter wave communication.

“…These types of DPAs are more suitable for channel capacity improvement especially in dense areas where we encounter user plane (UE) traffic [32]- [33]. The second category is related to DPAs featuring a different beam direction for each polarization [34]- [35]. These types of DPAs provide a wider coverage compared to the first category since the beam of each polarization targets different angles.…”

“…Several methods were proposed to realize a dually polarized LWA (DP-LWA), such as the dual-mode transmission line [38], symmetrical spoof surface plasmon polariton lines [39], back-to-back slot array [40], OMT based LWA [35], partially reflected surface (PRS) LWA [41], metamaterial LWA [42], and lens LWA [43]. However, all those methodologies can only provide a single beam operation for each polarization which makes them unsuitable for multibeam operations, which are essential in 5G new radio (NR) [44].…”

In this work, the concept of high-order space harmonics (HSHs) applied to a hybrid form of nonradiative dielectric (NRD) waveguide and substrate-integrated square waveguide (SIW) involving both TE10 and TE01 modes is investigated with aim to develop multi-functional dually polarized leaky-wave antennas (DP-LWAs). A polarization-selective coupling (PSC) mechanism is used to guide the two orthogonally oriented modes in the hybrid structure to achieve a polarization diversity feature. The polarization effect on unit-cell geometrical structures is examined for different characteristics of LWA such as propagation constant behavior, leakage ratio, and scanning range variation. In addition, we demonstrate how the extrinsic characteristics of HSHs in a one-dimensional periodic LWA and its unit-cell analysis can provide design flexibility through two case studies. In the first case of demonstration, we show a dually polarized multi-beam LWA design with wide scanning capability in which we use both even and odd HSHs of n ϵ [-1, -2]). The second antenna design case is concerned with a DP-LWA having the capability of fixed and scanning beams operation by using a combinatory set of PSC and four HSHs of n ϵ [-1, -2, -3, -4]. Two DP-LWA prototypes are demonstrated as proofs of concept, and the obtained experimental results show a very good agreement with their simulation and analysis counterparts.INDEX TERMS One-dimensional periodic leaky-wave antenna (1D-periodic LWA), Higher-order space harmonics (HSHs), Polarization-selective coupler (PSC), Nonradiative dielectric (NRD) waveguide, Substrate integrated waveguide (SIW), Dually polarized antenna (DPA).

“…In [18] and [19], the dual-beam radiation is realized by using two feeding ports and center-feeding structure, respectively. In [20] and [21], the second higher order mode of micro-CPW LWA and both TE 10 and TE 01 modes of a SIW LWA are used to generate the dual-beam radiation, respectively. In [22] and [23], two dual-beam LWAs using active components are demonstrated.…”

Dual-Beam and Tri-Band SIW Leaky-Wave Antenna With Wide Beam Scanning Range Including Broadside Direction

In this letter, a novel dual-beam and tri-band leaky-wave antenna (LWA) based on substrate integrated waveguide (SIW) structure is proposed, which has the capability of wide beam scanning range including broadside direction. The antenna consists of two kinds of periodic structures which can excite two -1st spatial harmonic waves and result in two radiation beams simultaneously. Through theoretical dispersion diagram analysis of the unit cells of two periodic structures and by applying the techniques of impedance-matching and reflection-cancelling, the open-stopbands at broadside are suppressed. Then the main beam of the proposed LWA can scan from backward to forward through broadside when frequency changes. Moreover, a tri-band application can be achieved in the dual-beam antenna by optimization of the second periodic structure. The measured results validate that the proposed SIW LWA has three operating frequency bands. In band 1 from 8.6 to 9.2 GHz, there is one beam scanning from 42 • to 71 • in the forward, in band 2 from 10 to 12 GHz, there is one beam scanning from -40 • to 4 • in the backward, and in band 3 from 12.5 to 15 GHz, there is a dual-beam scanning from -55 • to 54 • including broadside direction, which show good agreements with the simulated results.
