Abstract
A radio frequency (RF) front-end apparatus is provided. In examples discussed herein, the RF front-end apparatus can be configured to communicate RF signals in millimeter wave (mmWave) RF frequencies (e.g., ≥12 GHz). The RF front-end apparatus includes an RF front-end circuit and an antenna element. The RF front-end circuit includes a transmit path and a receive path for transmitting and receiving RF signals, respectively. The antenna element includes an input port(s) and an output port(s) that are coupled to the transmit path and the receive path, respectively. The antenna element can be configured to enable impedance matching between the input port(s) and the transmit path, as well as between the output port(s) and the receive path. As a result, it may be possible to reduce insertion losses in the RF front-end circuit, thus helping to improve performance of the RF front-end apparatus, particularly in support of mmWave communications.
