This article develops an efficient solution to design beam‐scanning transmitarray (TA). The four‐layer unit associated with the focal planar substrate integrated waveguide (SIW) array is presented and characterized. The proposed linearly polarized TA is implemented as four‐layer sheet admittance composed of the subwavelength unit, whose transmission feature would be accurate analyzed by the equivalent circuit model. The phase layout of TA is optimized by using the PMM method in order to achieve a wide scanning behavior and reduce the scan loss. Arc‐shaped SIW horn antenna array is adopted as the feeding source. Artificial impedance surfaces printed on either side against the low‐profile substrate results in a greatly enhanced radiation performance. The TA and feeds presented at 20 GHz are both fabricated using standard PCB processing. The measured results show a greatly improved ±45° scan range with the gain loss of 0.73 dBi by switching the SIW horn antenna. Good radiation and bandwidth characters are performed in all states of operation for both ports, confirmed the effectiveness of proposed design process.

A novel method for a beam pattern reconfigurable circularly polarized (CP) transmitarray antenna based on passive metasurface is proposed by a rearrangement of source antennas. Two source antennas among eight source antennas are selected for the fine beam steering. The beam steering angle can be finely controlled by the positions and phase difference of the source. Moreover, this kind of transmitarray antenna can be utilized to generate multibeam by the combination of the source antennas for radiation to different directions. To verify its feasibility, the planar CP source antenna is designed to operate at 5.8 GHz. Also, the metasurface consists of four layer separated by four substrates to cover full transmission phase variation of 2π, and the metallic layers are designed to circular patches. As a result, the steering angle is experimentally observed at each 0, +20, and +40°, and dual beam radiating to −30 and +30° also is measured.

Recent advances in the art of transmitarray antenna (TAA) designs are summarized in this article, mainly focusing on the TAA element designs, improved feeding mechanisms, methods of designing wideband and ultra‐wideband TAAs, and TAAs for beam‐steering applications. Firstly, according to the diverse‐phase shifting mechanisms, representative TAA elements in the available literatures are categorized into four groups, including the receiving–transmitting elements, multilayer frequency‐selective surface‐type elements, polarization‐conversion elements, and phase‐rotation elements. Based on their own specific properties, designers can flexibly select the proper elements for different application scenarios. Moreover, primarily aiming at reducing the overall profile, some improved feeding mechanisms are discussed, for example, the folded TAA, TAA with the feeds of the multihorn configuration, the auxiliary small TAA, the integrated leaky‐wave antenna, the Cassegrain reflectarray, or a small‐scale array antenna. Subsequently, numerous typical solutions to improve the inherently narrow bandwidths of the TAAs are also presented. It can be concluded that the wideband performances of the non‐true‐time‐delay TAA are realized by optimizing the element‐phase errors and transmission losses at all designing frequencies. If the true‐time‐delay elements are employed, the key point is utilizing their group delays to appropriately compensate the spatial phase delays. Finally, for highly demanded beam‐steering applications, the TAAs incorporated with the techniques of reconfigurable, mechanical scan, switched beam, or phased array antenna (PAA) feed are introduced. Specifically, representative designs of the PAA‐fed TAAs are presented in detail, which will be a promising technical candidate of high‐gain beam scanning antennas.
