摘要： PROBLEM TO BE SOLVED: To provide an antenna unit and a receiver of which a directional antenna is configured with a simple structure for space saving, and is mounted on a small wireless communication terminal to provide directivity. SOLUTION: An inverted L shaped antenna element 3 is supplied with a current from a feeding part 4 through the side surface of a mounting board 2 or its one side. The inverted L shaped antenna element 3 comprises a high dielectric element 5 of low loss in contact with its upper surface and having the area several times the inverted L shaped antenna element 3 including the antenna upper surface. The high dielectric element 5 is easily reduced in mounting area by employing a thin film type film adhesive tape or the like. In terms of mounting area, the area is widened in both width direction and length direction to cover at least the antenna element upper surface, thereby improving effect as an antenna. Relating to the high dielectric element 5, the values of antenna length, specific inductive capacity ε, and the mounting area of high dielectric material are set optimum so that the inverted L shaped antenna element 3 operates around 1/2λ to provide directional gain.

摘要： PROBLEM TO BE SOLVED: To highly precisely measure an SAR (specific absorption rate) value such as average SAR in a simple method and simple apparatus constitution at a high speed. SOLUTION: A specific absorption rate measuring apparatus for a wireless device measures a near magnetic field of an electric wave radiated from a reference wireless device or a reference antenna in a free space, measures a specific absorption rate (SAR) concerning the electric wave radiated from the reference wireless device or the reference antenna by using a phantom in a prescribed measuring method, and previously calculates a conversion coefficient α by dividing the measured specific absorption rate (SAR) by a square value of the measured near magnetic field. An SAR calculation controller 20 measures the near magnetic field of the electric wave radiated from the wireless device of an object to be measured in a free space, and estimates and calculates the specific absorption rate (SAR) concerning the electric wave radiated from the wireless device of the object to be measured by multiplying the conversion coefficient α calculated into the square value of the measured near magnetic field.

摘要： PROBLEM TO BE SOLVED: To provide a small-sized and broad-band antenna arrangement, in which reduction in gain is lessened, even in a state of being used in proximity to a human body. SOLUTION: A rectangular 1 wavelength loop antenna element 103 is installed in proximity to a wireless installation ground plate 101, and further both ends of the loop antenna element 103 are bent toward a power supply part, thereby configuring a current distribution in which a current at the uppermost tip part of the bending is brought to zero. Furthermore, a current is concentrated on the loop antenna element 103, thereby reducing the current components flowing in the wireless installation ground plate 101, to suppress influences when the human body holds it in the hands, and also to form directional characteristics in correspondence with the incoming waves.

摘要： PROBLEM TO BE SOLVED: To enhance an antenna characteristic of a mobile wireless device provided with an antenna when the mobile wireless device is actually used. SOLUTION: A hinge section 40 turnably couples a device body case 20 and a cover case 30 of a mobile phone 10. Furthermore, the device body case 20 is made of a resin material, a metal or a material including the metal, and the cover case 30 is made of a metallic material. Furthermore, since the cover case 30 is placed on a side face of an antenna 50 when the mobile phone 10 is in use, a current easily flows through the cover case 30, and a current flowing through the device body case 20 is decreased so as to reduce disturbance in the current distribution when a user holds the device body case 20 in its hand, thereby reducing deterioration in the antenna gain.
