Claim of US Patent No. 10,117,325

1. A mobile terminal comprising:a case;
a first main board provided in an upper area within the case, a second main board provided in a lower area within the case, and a connection board that connects the first main board and the second main board with each other,
wherein the connection board includes:
two transmission lines that extend in a first direction to transmit a signal; and
a guard pattern provided between the two transmission lines, the guard pattern preventing electrical interference between the two transmission lines and including a plurality of slots, at least one of the slots having a respective open end and a corresponding closed end in a second direction, wherein the first guard pattern includes:
a first pattern that extends in the first direction, a first width of respective ends of the first pattern being larger than a second width of a middle portion of the first pattern; and
a plurality of second patterns arranged side by side along the first direction,
wherein adjacent ones of the plurality of second patterns extend in the second direction, which is perpendicular to the first direction, to intersect the middle portion of the first pattern at right angles thereto, and
wherein the first pattern and the plurality of second patterns are connected and form the plurality of slots between adjacent ones of the plurality of second patterns.
