“…This is the key distinct feature of the proposed design as compared to 20,21,23‐25,28,30,36‐40 . The reported SLL in 20,21,23,24 are lower than the one presented in this paper. It should be noted that the reported antennas in 21,23,28 were fed by coaxial through‐hole connectors, which is not a practical feeding mechanism for the low‐profile antenna.…”

“…LWA is a traveling wave antenna in which the wave leaks into space through the discontinuities 8‐38 . LWAs are categorized into uniform, 13‐18 quasi‐uniform, 19‐24 and periodic 25‐29 Uniform LWA has a uniform cross‐section containing a single long slot. While quasi‐uniform and periodic LWAs have periodic cross‐sections and radiation occurs from the periodic slots on the surface of the antenna.…”

“…The size of the SIW can be reduced by removing half of the structure. This new structure is called half‐mode substrate integrated waveguide (HMSIW), 16‐20 wherein radiation occurs from the long open aperture. SIW‐based LWA has better control over the radiation than the HMSIW‐based LWA because of the usage of thin slots.…”

A novel method for confining the undesired radiation of the feed transition of a low‐profile leaky‐wave antenna (LWA) is demonstrated in this paper. The proposed design method uses novel tapered CPW transitions resulting in variation of the parasitic capacitance and electrical length of the feed. This leads to the reduction of the side‐lobe level (SLL), which is dictated by the feed and the slotted sections of the antenna. The undesired radiation from the feed becomes crucial in the low‐profile antenna in which the surface‐mounted connector along feed transition is the only practical feeding mechanism. The key novelty of the proposed approach is the reduction of SLL by exclusively modifying the feed structure rather than the slotted radiation section. To validate the proposed approach, a modified compact feeding mechanism for LWA is designed. The antenna is realized based on the substrate integrated waveguide (SIW). The antenna's length, width, and height are 110 mm, 31 mm, and 0.5 mm, respectively. The operating frequency band was chosen as 26 to 30 GHz, covering an allocated 5G band. The measured peak realized gain and SLL are 6.1 dBi and − 11.4 dB, respectively. An improvement of 5.7 dB in SLL compared to the conventional LWA was observed. The simple fabrication process and efficiency of the proposed method make it a viable approach for reducing the SLL of the low‐profile antennas. Compactness, low SLL, and proper gain of the reported antenna make it a suitable candidate for 5G vehicle to everything (V2X) communications and mm‐wave navigation systems.

A leaky wave antenna (LWA) based on half-mode substrate integrated waveguide (HMSIW) is presented. Integrated phase inverters are used to eliminate the far-field cancelation from the adjacent radiating element with half-wave spacing. The ground plane is extended to reflect the quasi-magnetic-dipole radiation pattern from the backfire to the boresight for enhanced antenna gain. Two linear arrays with differential feeding are deployed back-to-back along their longitude, by which the far-field radiation adds constructively that leads to further increased antenna gain. The proposed antenna features shorter electric length compared with counterparts of the same gain. Agreement is achieved between simulation and measurement. The proposed antenna has a measured impedance bandwidth of 11-12.8 GHz (15.6%), the measured maximum gain of 16.2

In this article, a multi-resonance frequency scanning antenna with a Luneburg lens is designed. This antenna operates in the X-band and can achieve beam steering by changing the frequency in this band. The steering angle of the designed model is ±50 . This antenna is a good candidate for a wide range of telecommunication, automotive radar, and search radar applications. The advantage of this model over most of other works in this field is that just one multi resonant slot antenna in front of the Luneburg lens is used instead of several antennas and separate feed networks. This development leads to a compact structure with more straightforward and cost-effective fabrication. The antenna structure is based on a substrate integrated waveguide technology. Full-wave simulations are performed using the software of CST. The proposed model is designed and fabricated on Rogers RO4003C substrate with a height of 20 mils. A perforated Teflon sheet is designed and fabricated to approximate the inhomogeneous refractive index of the Luneburg lens.
