An RF antenna includes a first substrate having a first top surface and a first bottom surface and a second substrate having a second top surface and a second bottom surface, wherein the first substrate is disposed on top of the second substrate, the second bottom surface including a ground plane disposed thereon. The RF antenna further includes a low-band (LB) radiation element disposed on the first top surface of the first substrate. The LB radiation element is to resonate within a first frequency band to transmit and receive RF signals associated with the first frequency band. The RF antenna further includes multiple high-band (HB) radiation elements disposed between the first bottom surface of the first substrate and the second top surface of the second substrate. Each HB radiation element is to resonate within a second frequency band to transmit and receive RF signals associated with the second frequency band.

Antenna element structure suitable for 5G CPE devices

According to one embodiment, a waveguide antenna includes a top plane made of electrically conductive material, a bottom plane made of electrically conductive material, a first feed member coupled to the top plane and the bottom plane through a first via, the first feed member to be electrically coupled a transceiver of an electronic device, and an array of vias disposed surrounding the first via. The array of vias coupling the top plane and the bottom plane to form a cavity between the top plane and the bottom plane. When an electrical signal is provided to the first feed member, the first feed member excites a space within the cavity between the top plane and the bottom plane.

Waveguide antenna with cavity

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.
