## Abstract

A human phantom apparatus is provided with a body section, a head section connected with the body section, at least one shoulder section connected with the body section, and an arm section including a hand section, the arm section connected with the shoulder section. Each of the body section, the head section, the at least one shoulder section, and the arm section is filled with a human body equivalent material. The human phantom apparatus has a so-called PDA (Portable Digital Assistance) attitude of holding a radio communication apparatus by the hand section of the arm section, so that the human phantom apparatus looks at a display unit of the radio communication apparatus in front of the body section.

## Claims

### Claim 1

An antenna characteristic measurement apparatus for measuring a characteristic of an antenna of a radio communication apparatus using a human phantom apparatus,
wherein said human phantom apparatus comprises:
a body section;
a head section connected with said body section;
at least one shoulder section connected with said body section; and
an arm section including a hand section, said arm section connected with said shoulder section,
wherein each of the body section, the head section, the at least one shoulder section, and the arm section is filled with a human body equivalent material,
wherein the human phantom apparatus has an attitude of holding a radio communication apparatus by the hand section of said arm section, so that the human phantom apparatus looks at a display unit of the radio communication apparatus in front of said body section,
wherein said antenna characteristic measurement apparatus comprises a control device for measuring the characteristic of the antenna of the radio communication apparatus, by changing at least one parameter selected from (a) an interval between said body section and the radio communication apparatus, (b) an inclined angle of the radio communication apparatus with respect to a horizontal direction, and (c) a height of the radio communication apparatus,
wherein said human phantom apparatus comprises a finger phantom apparatus, and
wherein said finger phantom apparatus comprises:
a hollow fingertip section made of an elastic material; and
a hollow finger root section made of a dielectric material,
wherein said fingertip section and said finger root section are filled with a human body equivalent material, and are sealed.

### Claim 2 (depends on 1)

The antenna characteristic measurement apparatus as claimed in claim 1,
wherein the characteristic of the antenna of said radio communication apparatus is measured in such a state that said fingertip section is brought into contact with an input device of said radio communication apparatus.
