Rotation symmetric bent functions and their generation two-rotation symmetric bent functions are two classes of cryptographically significant Boolean functions. However, few constructions have been presented in the literature, which either have restriction on integer <inline-formula> <tex-math notation="LaTeX">$n$ </tex-math></inline-formula> or have algebraic degree no more than 4. In this paper, for any even integer <inline-formula> <tex-math notation="LaTeX">$n\ge 4$ </tex-math></inline-formula>, three classes of bent functions are presented respectively. Most notably, the proposed <inline-formula> <tex-math notation="LaTeX">$n$ </tex-math></inline-formula>-variable rotation symmetric bent functions and two-rotation symmetric bent functions can have any possible algebraic degree ranging from 2 to <inline-formula> <tex-math notation="LaTeX">$n/2$ </tex-math></inline-formula>. Besides, we obtain bent idempotent functions with the maximal algebraic degree <inline-formula> <tex-math notation="LaTeX">$n/2$ </tex-math></inline-formula>.
