Abstract: An antenna according to one embodiment of the present invention comprises: a first radiation part formed in a cover shape on a first surface of a printed circuit board; and a second radiation part penetrating the printed circuit board from one end of the first radiation part and extending onto a second surface of the printed circuit board, wherein the second radiation part includes a radiation pattern on the second surface of the printed circuit board, and the radiation pattern is spaced apart at a predetermined distance from a grounding pattern formed inside the printed circuit board or on the first surface of the printed circuit board.

Abstract: A network interface apparatus for wireless Ethernet is provided. The network interface apparatus includes: a Network Interface Card (NIC) control unit for converting a gigabit wired Ethernet signal into a Peripheral Component Interconnect express (PCIe) signal; a wireless network processing unit for converting the PCIe signal received from the NIC control unit into an analog signal; and an RF transmitting/receiving unit for converting the analog signal inputted from the wireless network processing unit into an RF signal of a 60 GHz frequency band to transmit the converted RF signal into a wireless terminal device.
