Abstract
An antenna device includes: a substrate; a first ground plate arranged in a first layer and disposed on the substrate; a first signal port and a second signal port arranged in a second layer adjacent to the first layer and configured to transmit a first radio-frequency (RF) signal and a second RF signal, respectively; a first feed line and a second feed line arranged in the second layer and connected to the first signal port and the second signal port, respectively; and a radiation element disposed over the substrate. The substrate is arranged to provide a first signal channel and a second signal channel between the radiation element and the first or second feed line for transmitting the first and second RF signals, the first feed line and the second feed line have different line lengths, and the radiation element at least partially overlaps the first and second signal channels.
