Abstract
A dipole antenna with resonant cavities operates with a resonant frequency near the antenna operating frequency to widen the operating bandwidth of the dipole antenna. Specifically, a ground consisting of multiple layers of electrically conductive planes and electrically conductive vias connecting the electrically conductive planes to form a ground wall cavity for a dipole member. The ground wall induces multiple resonant frequencies due to its coupling effect to the dipole member. A radio frequency (RF) frontend for mobile communication devices contains the dipole antenna with cavity coupled to a transceiver to receive and transmit communication signals.
