Bentuk elemen tampalan novel dengan struktur interdigital dan multi-via untuk pemantul metasurface jenis cendawan dicadangkan untuk mengawal fasa pantulan. Struktur interdigital menyediakan julat fasa refleksi yang luas dengan menukar kedalaman jari interdigital. Selain itu, struktur berbilang melalui menyediakan fasa pantulan positif yang lebih tinggi seperti berhampiran +180°. Julat fasa pantulan yang mencukupi 360° dan sifat bergantung kepada polarisasi yang rendah boleh disahkan oleh simulasi medan elektromagnet. Reflektor metasurface untuk gelombang satah kejadian biasa telah direka. Sudut pantulan yang dikehendaki dan corak medan jauh yang tajam bagi rasuk pantulan boleh disahkan dalam keputusan simulasi. Reflektor prototaip untuk eksperimen hendaklah direka bentuk dengan cara yang sama seperti reka bentuk reflektor utama antena pemantul. Secara khusus, kaedah reka bentuk reflektor berdasarkan kaedah pengesanan sinar menggunakan fasa gelombang kejadian telah dicadangkan untuk prototaip. Corak sinaran eksperimen untuk antena pemantul yang terdiri daripada antena pemancar (TX) dan pemantul metasurface prototaip adalah serupa dengan corak sinaran simulasi. Keberkesanan struktur yang dicadangkan dan kaedah reka bentuknya boleh disahkan oleh hasil simulasi dan eksperimen ini.

Abstract: The novel patch element shapes with the interdigital and multi-via structures for mushroom-type metasurface reflectors are proposed for controlling the reflection phases. The interdigital structure provides a wide reflection phase range by changing the depth of the interdigital fingers. In addition, the multi-via structure provides the higher positive reflection phases such as near +180°. The sufficient reflection phase range of 360° and the low polarization dependent properties could be confirmed by the electromagnetic field simulation. The metasurface reflector for the normal incident plane wave was designed. The desired reflection angles and sharp far field patterns of the reflected beams could be confirmed in the simulation results. The prototype reflectors for the experiments should be designed in the same way as the primary reflector design of the reflector antenna. Specifically, the reflector design method based on the ray tracing method using the incident wave phase was proposed for the prototype. The experimental radiation pattern for the reflector antenna composed of the transmitting antenna (TX) and the prototype metasurface reflector was similar to the simulated radiation pattern. The effectiveness of the proposed structures and their design methods could be confirmed by these simulation and experiment results.
