Embodiment 1）

[0067] Argon was introduced as a gas for plasma generation at 40 L / min into the chamber of the high-frequency induction thermal plasma apparatus to generate plasma. Fe powder with an average particle size of 10 μm and Al powder with an average particle size of 3 μm are sprayed into the plasma in the chamber at a rate of 3 L / min together with argon (carrier gas) at a mass ratio of Fe to Al of 20:1 . At the same time, acetylene gas, which is a raw material for carbon coating, is introduced into the chamber together with a carrier gas. Thus, nanoparticles in which FeAl alloy particles were coated with carbon were obtained.

[0068] The carbon-coated FeAl alloy nanoparticles were subjected to a reduction treatment at 500 mL / min of hydrogen flow at 600°C, cooled to room temperature, and then taken out into an argon atmosphere containing 0.1% by volume of oxygen and oxidized to produce a nucleus. Shell type soft magnetic powder. The obtained core-shell type soft magnetic powder h...

Description

technical field [0001] Embodiments of the present invention relate to an antenna component and a method of manufacturing the same. Background technique [0002] With the rapid increase of communication information, miniaturization and weight reduction of electronic communication equipment are being pursued. Therefore, miniaturization and weight reduction of electronic components mounted on electronic communication equipment are urgently required. The frequency band of radio waves used by current mobile communication terminals for information transmission is a high-frequency region of 100 MHz or higher. In portable mobile communication or satellite communication, radio waves in a high frequency band of the GHz band are used. Therefore, there is a demand for electronic components useful in the high frequency region. [0003] In order to deal with radio waves in the high frequency band, the energy loss and transmission loss of electronic components are required to be small, w...
