The effect of the structure YBa{sub 2}Cu{sub 3}O{sub 7-x} superconducting thin films on microwave surface resistance R, is strongly correlated with the perfection of the thin films. The films were deposited on LaAlO{sub 3}(100) and YSZ(100) substrates. For thin film with R{sub s} of 280 {mu}{omega}, the crystallinity of the thin film shown by w-scanning and {phi}-scanning was excellent and the ECPs were very sharp. For thin film with high R, of 98 m{omega}, only bands was excellent from the major zone were visible in the ECPs, which suggested poor crystallinity of the film. From this investigation it was shown that the more perfect the thin films, the lower the R{sub x}.
