摘要： An antenna device and a mobile radio communication terminal adapted for improving the performance of an antenna. The antenna device includes a radio circuit for transmitting and receiving a high-frequency signal, a notch antenna having a feeder, and a notch antenna operating through electromagnetic coupling with the notch antenna, and a substrate independent of the radio circuit with respect to high frequencies. The notch antenna includes a linear slit having a length of λ/4 and cut from one edge of the substrate on the reverse side to the position of the radio circuit. The notch antenna includes a linear slit having a length slightly shorter than λ/4 and cut in parallel with the notch antenna from the same edge thereof at a position spaced apart by a predetermined distance d from the notch antenna.

摘要： The present invention makes it possible to realize an antenna device and a portable radio set capable of greatly reducing the deterioration of antenna characteristics while used near a human body and greatly reducing the deterioration of communication quality by electrically connecting first and second antenna elements to a balanced-to-unbalanced transform circuit by connection means when a first antenna element is retracted, supplying power to the first and second antenna elements from an unbalanced transmission line through balanced-to-unbalanced transform means to operate the first and second antenna elements as antennas, preventing a leakage current from flowing to a ground member to which the unbalanced transmission line is grounded from the first and second antenna elements through the transmission in accordance with the balanced-to-unbalancecd transform by the balanced-to-unbalanced transform means, and thereby preventing the ground member from operating as an antenna.

摘要： This invention provides a method of forming a powder compact which can produce a high density compact under a high pressure and at the same time can reduce pressure for ejecting the compact from a die.This method comprises the application step of applying a higher fatty acid lubricant to an inner surface of a heated die, and the compaction step of filling metal powder into the die and compacting the metal powder under such a pressure as to force the higher fatty acid lubricant to be chemically bonded with the metal powder and form a metallic soap coating. Since the metallic soap coating is formed between the die and a compact, friction force between the die and the compact is decreased and ejecting pressure can be remarkably decreased despite of compaction with high pressure. Besides, a high density compact can be obtained owing to the compaction with high pressure.

摘要： An antenna device includes a flat ground conductor; a first flat radiation conductor disposed against the flat ground conductor interposing a first dielectric layer; a first short-circuit conductor connecting an end of the first flat radiation conductor and the flat ground conductor; a second flat radiation conductor disposed partly against an opposite side of the first flat radiation conductor with its other side facing the ground conductor interposing a second dielectric layer; a second short-circuit conductor connecting an end of the second flat radiation conductor and the flat ground conductor; and a supply point disposed on the first flat radiation conductor. With this structure, the first flat radiation conductor and the second flat radiation conductor are disposed partly against each other, which enables more size reduction than that of conventional antennas operating at the same resonant frequency.
