  • Publication number: 20230118173
    Abstract: Presented is an antenna module for wireless power transmission and reception in which an inner loop pattern is disposed in the inner peripheral area of an outer loop coil so as to provide a constant charging recognition rate regardless of location. The presented antenna module for wireless power transmission and reception comprises: a base substrate; a first antenna which is disposed on the upper surface of the base substrate and includes a first radiation pattern forming a first loop; and a second antenna which is stacked on the upper surface of the base substrate and includes a coil wound along the outer periphery of the first loop to form a second loop.

  • Patent number: 9673509
    Abstract: Provided are an antenna module for a portable terminal and a portable terminal including the same, wherein a slot is formed on a base sheet on which an NFC antenna and a wireless charging antenna are stacked, thereby minimizing a height difference between the NFC antenna and the wireless charging antenna. The provided antenna module for a portable terminal enables the NFC antenna and the wireless charging antenna to be stacked on an upper side of the base sheet having the slot, wherein opposite ends of the wireless charging antenna pass under a lower end of the NFC antenna while passing through the slot of the base sheet, and are connected to a power supply terminal of a portable terminal.

  • Publication number: 20120280867
    Abstract: Disclosed herein is an internal antenna module that is installed in a terminal and that can receive signals in both the FM and Bluetooth frequency bands so as to achieve a small-sized, slim terminal. The internal antenna module includes a polyhedral chip antenna configured to have a first radiant pattern and a coupling pattern formed thereon, a flexible circuit board configured to have a first conductive pad connected to the first radiant pattern, a second conductive pad connected to a coupling pattern, and a second radiant pattern connected to the first radiant pattern, and a signal switching unit formed between the second conductive pad and a ground, and configured to prevent any one of a first frequency band signal and a second frequency band signal, received through the chip antenna and the flexible circuit board, from reaching the ground.
