Abstract: A substrate integrated waveguide having multiple substrate comprises a first substrate and a second substrate stacked with the first substrate, wherein metal layers are formed on opposite sides of the first substrate and opposite sides of the second substrate, a plurality of metal holes are formed between two metal layers of the same substrate to limit transmission paths of electromagnetic waves transmitted in the substrate, and areas having no metal therein are formed between the first and second substrates so that the electromagnetic waves could be transmitted between the first and second substrates thereby.

Abstract: An antenna cover is used with an antenna for passing therethrough a radiation of the antenna in order to modify an antenna pattern of the antenna. The antenna cover includes a housing having a first surface and a second surface; and a plurality of through holes penetrating through the housing and extending from the first surface to the second surface. By way of adjusting distances between the plurality of through holes and/or adjusting sizes of the plurality of through holes, the antenna cover functions to adjust the radiation of the antenna from a first antenna pattern to a second antenna pattern.
