Patent Description:
While the size of electronic devices is gradually becoming smaller, as the functions of electronic devices become more diverse, it has become important to ensure a space where electronic components (e.g., a processor, a communication circuit, or a memory) for executing various functions of the electronic devices can be disposed in high density.

Recently, in order to ensure the space in which electronic components may be disposed, electronic devices including a stacked structure of multiple printed circuit boards that is configured by using an interposer have been increasing. For example, in an electronic device, a space for electronic components may be ensured by stacking multiple printed circuit boards and placing interposers including at least one via configured to electrically connecting the printed circuit boards between the stacked printed circuit boards.

An electronic device provided with an antenna and stacked printed circuit boards electrically connected via an interposer and conductive metal brackets is known from <CIT> Al.

<CIT> discloses a similar electronic device with a stable electromagnetic shielding structure between various electrical components.

Electronic components related to transmission of RF signals may be disposed on some of multiple stacked printed circuit boards.

However, when these electronic components operate in a state in connection with an unstable ground of a printed circuit board, RF signal radiation performance may be degraded by generating noise and unwanted waves.

According to an embodiment, by implementing a stable connection path with a ground for noise electronic components, it is possible to reduce antenna performance degradation.

Preferred embodiments of the invention are matter of the dependent claims.

According to various embodiments of the disclosure, by adding a stable ground connection structure for electronic components related to RF signal transmission, it is possible to reduce radiation performance degradation.

According to various embodiments of the disclosure, by connecting and using different ground areas via a separate structure, it is possible to implement antennas configured to transmit and receive signals in different frequency bands.

In addition, various effects that may be directly or indirectly appreciated through this disclosure may be provided.

In connection with the description made with reference to the drawings, the same or substantially the same components may be denoted by the same reference numerals.
