Abstract
We have fabricated EuBa2Cu3O7-delta Josephson junction arrays of two d ifferent sizes to improve detection output and microwave coupling betw een junctions and an rf source. The arrays contain three weak link gra in boundary junctions made on an MgO bicrystal substrate. It is demons trated that both the junction array configuration and smaller junction size are effective in improving microwave coupling and hence in incre asing the responsivity. The best responsivity obtained is 1085 V/W for broadband detection at 11.9 GHz.
