Antenna system for transmitting and receiving mm-wave signal

A millimeter wave communication device of an electronic device, comprising:

• an antenna printed circuit board (PCB) including a plurality of layers;
• an integrated circuit (IC) positioned under the antenna PCB;
• a first feed line electrically connected with the IC and extending to a first layer through one or more of the plurality of layers of the antenna PCB, wherein a first portion of the first feed line is disposed in the first layer and has a first length;
• a second feed line spaced from the first portion of the first feed line and disposed in a second layer of the antenna PCB, the second layer being an upper layer of the first layer, so as to be electrically coupled with the first portion of the first feed line;
• and
• a first antenna element electrically connected with the second feed line in a third layer of the antenna PCB, the third layer being an upper layer of the second layer,
• wherein the IC is configured to transmit and/or receive a millimeter wave (mm-wave) signal using the first feed line, the second feed line, and the first antenna element.
