dc.description.abstract | In this work we design, simulate, manufacture and measure blocks made of variable density plastic. The density is controlled through varying the size of small cubes at the intersections of a fine grid. This structure is inspired by [1]. Simulations using HFSS show that there is a consistent relation between plastic density and relative permittivity (εr), and this is confirmed by measurements of 24 blocks with different density. Finally, an example design utilizing this is presented; a gradient index lens (GRIN) with continuously varying εr. 3D printed GRIN lens has been presented in [2], but in that case with stepwise varying εr. The GRIN lens was measured in an anechoic chamber, and about 5dB increased gain was demonstrated over the entire bandwidth of 7.5-18GHz. | en_GB |
