Description
Technical Field
The invention relates to the technical field of waveguide slot array antennas, in particular to an E-plane waveguide full-parallel feed broadband high-gain slot antenna.
Background
In general, the bandwidth of an array antenna depends on the bandwidth of the array elements and the bandwidth of the feed network. The bandwidth of the feeding network is closely related to the feeding form and the bandwidth of the feeding element (such as a power divider). The waveguide slot array antenna has the characteristics of high efficiency, low loss, low profile and high power capacity. Its feed network can be divided into three kinds of series feed, parallel feed and series-parallel (or partial parallel) feed. When a series feed is employed, beam scanning can be achieved by frequency change. But due to the long line effect (M.Ando, Y.Tsunemitsu, M.Zhang, J.Hirokawa and S.Fujii, "Reduction of Long line Effects in Single-Layer Slotted Waveguide Arrays With an embedded partition corporation Feed," IEEE trans.antennas Propag., vol.58, No.7, pp.2275-2280, July 2010.), the match and gain bandwidth decrease as the array size, the number of series fed array elements increase. When parallel feed is adopted, the lengths of the feed lines from the feed source to each array element are equal, and the feed amplitude and the phase position do not change along with the frequency, so that the long-line effect does not exist, the matching and gain bandwidth is larger, but the feed network is more complex, the processing cost is higher, and beam scanning is not easy to realize. Series-parallel feeding is a combination of series feeding and parallel feeding, and advantages and disadvantages are between the two feeding forms.
Conventional parallel feed air waveguide slot antennas, (y.miura, j.hirokawa, m.ando, y.shibuya, and g.yoshida, "Double-layer full-polarized-fed hole-waveguide slot in the 60-GHz band," IEEE trans.antennas propag, vol.59, No.8, pp.2844-2854, aug.2011.), and a feed network employs an H-plane waveguide to excite a 2 × 2 element antenna subarray, and it is because of the large broadside size of the H-plane waveguide, perfect full parallel feed cannot be realized to excite each radiating element. Incident electromagnetic waves pass through a power division network consisting of H-plane waveguides on the lower layer of the antenna, excite the resonant cavity structure on the upper layer through an excitation gap, and then radiate to an external space through a radiation gap on the surface of the resonant cavity. Because the broadside size of the air waveguide is larger than half of the wavelength of the free space, and the distance between the output ports of the H-plane waveguide power distribution network is larger than one wavelength of the free space, a radiation gap cannot be directly formed at the tail end of the output waveguide, otherwise, a radiation directional diagram has grating lobes, and the gain and the radiation performance of the antenna are seriously reduced. Therefore, a 2 x 2 unit radiation subarray is adopted to replace a single radiation gap, a resonant cavity is loaded on the upper layer of the feed waveguide through an excitation gap, and 2 x 2 radiation gaps with equal amplitude and same phase are formed by notching four corners of the upper surface of the resonant cavity, so that the array element spacing is smaller than one air wavelength, and a grating lobe is eliminated. However, in a 2 × 2 unit radiation subarray, the relative amplitude and phase of each array element excited by a resonant cavity cannot be independently controlled, grating lobes occur when low side lobes or special beam forming is realized, and certain design limitations exist. For example, when taylor distribution is realized, since 4 array elements in a 2 × 2 element sub-array are excited in phase with equal amplitude, ideal taylor distribution cannot be realized, and grating lobes appear in the radiation pattern. In addition, in the conventional processing of the parallel feed air waveguide slot antenna, a numerical control machine is usually adopted to mill or linearly cut a metal plate, a desired pattern is etched on the metal plate, and then the metal plates are welded layer by layer through welding processes such as diffusion welding or vacuum brazing to form a complete antenna, but the welding processes such as diffusion welding or vacuum brazing are usually carried out in a high-temperature high-pressure and vacuum environment, so that the processing has the defects of great difficulty, long time, high cost and incapability of continuous batch production. In order to solve the grating lobe problem caused by a 2 × 2 unit antenna subarray, some scholars propose a full parallel feed waveguide slot array antenna structure with an antenna subarray of 1 × 1, and the key technology is how to reduce the size of a transmission line and realize the placement of output ports of a power division network in a space smaller than one air wavelength.
A Substrate Integrated Waveguide (SIW) is used as a novel waveguide form, and is based on an H-plane medium filled rectangular waveguide, and a metal side wall of a traditional waveguide is replaced by metallized through holes which are punched in the medium and are continuously arranged, so that electromagnetic waves can be limited in the substrate integrated waveguide for directional transmission, and no leakage is generated. Compared with an air waveguide, although the dielectric filling brings extra loss, the broadside dimension of the dielectric filling waveguide can be smaller than half of the free space wavelength, and as long as a medium with a proper dielectric constant is selected, the distance between the output ports of the Substrate Integrated Waveguide (SIW) based power distribution network can be smaller than one free space wavelength. The Substrate Integrated Waveguide (SIW) is usually processed by a PCB process or an LTCC process, and has the characteristics of simple process, low processing cost, and easy mass production. However, with the introduction of metal posts and media, waveguide height is generally small, increasing metal and dielectric losses. Especially at high frequencies, the gain of a substrate integrated waveguide slot antenna is much lower compared to an air waveguide antenna. (Chinese patent 201810534714.9)
The gap ridge waveguide forms an electromagnetic band gap structure by adding periodic metal columns on two sides of the ridge waveguide, so that only a quasi-TEM mode is transmitted in the waveguide in a specific frequency, and a gap exists between an upper layer metal plate and a lower layer metal plate without welding. In order to prevent the leakage wave, two or more rows of metal columns are generally needed on two sides of the ridge, so that the distance between the ridge and the ridge is too large, and the power divider cannot be placed at a distance smaller than one air wavelength. By optimizing the height between the ridge and the upper metal plate, the height and width of the ridge, the isolation between two gap ridge waveguides is high in the case of using only one row of metal posts, so that the power divider can be simply cascaded to form a full parallel feed network (j.liu, a.vosogh, a.u.zaman, and j.yang, "a slot array with single-layer co-polarized-fed junction waveguide in the 60GHz band," IEEE ns.antennas propag, vol.67, No.3, pp.1650-1658, and ma.2019.). The frequency range of the transmission of the fundamental mode of the gap ridge waveguide is large, the bandwidth of a feed network formed by the gap ridge waveguide is large, but compared with a rectangular air waveguide, the loss of the gap ridge waveguide is slightly high, the large-scale array combination is not facilitated, and although the gap ridge waveguide does not need to be welded, the large-scale gap ridge waveguide slot array needs a large number of metal columns. Particularly in a high-frequency band, the sizes of the ridge and the metal column are reduced, the requirement on the machining precision is high, and the machining difficulty and the cost are greatly improved compared with those of a rectangular air waveguide machined by the same process of a numerical control machine tool and the like.
