PROBLEM TO BE SOLVED: To provide a cable antenna which is small, lightweight, and nondirectional. SOLUTION: The antenna apparatus comprises a coaxial cable having a core conductive wire for feeding signals and a radiation unit coupled to the coaxial cable. The material and characteristic of the radiation unit are substantially the same as those of the coaxial cable. The length of the radiation unit is approximately ((1/4)+n) of an operation frequency of the antenna apparatus, wherein the n is an integer that is greater than or equal to zero.
