在this,that,next,last,every,yesterday,tomorrow等构成的时间状语前不加任何介词.
（last year,this month,next week,last Saturday,every day,yesterday afternoon,tomorrow morning/evening）
而 the weekend 前要加 at/on

this weekand 就相当于on the weekend this前不能加at和on

加不加无所谓

第一，你的句子错了，应该是 I want to have a relax this weekend. 没有用relaxation的。
第二，this weekend 和 on weekend 的区别:
this weekend 说的是这个周末，
on weekend 统称周末，如 what do you usually do on weekend? 可以指这个也可以泛指周末。
