ABSTRACT:
An antenna unit comprises a hollow cylindrical member obtained by forming a flexible insulating film member into a hollow cylinder. An antenna pattern composed of at least one conductor is formed at the hollow cylindrical member. The antenna unit further comprises a board mounted with a low-noise amplifier and a hollow cylindrical cover case covering the hollow cylindrical member and the board. In order to reduce the size in longitudinal direction, a part of the board is inserted into the inside of the hollow cylindrical member.
