ELECTRONIC DEVICES AND ANTENNA CIRCUITS

Abstract

The invention relates to an electronic device and an antenna circuit. Such an electronic device, by a method revealed in the invention, may consist of a printed circuit board (PCB) of multiple layers, a communication circuit electrically connected to the PCB, and at least one processor electrically connected to the communication circuit. The PCB may include a first layer in which multiple patch antennas are arranged. The first power supply line directly or indirectly supplies power to the first point of the first patch antenna so that the first patch antenna is positioned with the first layer transmitting and / or receiving the first polarization signal, wherein the first power supply line consists of a path through several first layers among many layers and is connected to the communication circuit; the second power supply line directly or indirectly supplies power to the second point of the first patch antenna so that the first patch antenna is positioned for the first layer transmitting and / or receiving the second polarization signal orthogonal to the first polarization signal.In this design, the second power supply line consists of a line that passes through several of the first layers and is electrically connected to the communication circuit; the second layer consists of the grounding section; the first grounding line connects the grounding part and the third point adjacent to the first point of the antenna from the outside of the first antenna; and the second grounding line connects the grounding part and the fourth point adjacent to the second point of the first antenna from the outside of the first antenna. Other different options identified through the description are also possible.
