Crossed Ring Antenna is using a 2-D planar structure design to form low cost aperture arrays. However, using the conventional PCB based conducting materials to build the radiating or receiving antenna surfaces for large scale applications, such as Square Kilometre Array, is still costly. 2-D material like printed graphene implemented by forming conductive ink with graphene nanoflakes can be a promising...
Different geometry arrangement for elements in an array yields various electrical interactions between them. In a wide band and wide scan angle array, these interactions are quite complex. A smart array structure is proposed based on the planar octagonal ring antenna. Thanks to the flexibility of this array element, element sizes and the bonds between the elements in the array can be non-uniform,...
