PROBLEM TO BE SOLVED: To provide an antenna device which easily controls antenna characteristics without increasing of the size and without performing complex control, and a communication device. SOLUTION: Extensions 120A to 120D and 220A to 220D are provided at conductor elements 100A to 100D and 200A to 200D of loop conductors 100 and 200. The extensions 120A to 120D and 220A to 220D are operated using nuts 133a to 133d and 233a to 233d, so that lengths of the conductor elements 100A to 100D and 200A to 200D can be flexibly changed.
