ADMV2228

The ADMV2228 is a dual-polarized, surface-mount, single-element antenna on board. The ADMV2228 operates between 24.0 GHz and 29.5 GHz and is capable of operating in the 5G New Radio (NR) N257, N258, and N261 frequency bands. The ADMV2228 simplifies antenna array board design by providing the entire element antenna stackup in a surface-mount component that enables the design and assembly of small or large arrays based on the application.

The ADMV2228 has symmetric feeds and radiation patterns for both polarizations, allowing for rotation of the device on the board depending on the feeding scheme.

The ADMV2228 can operate as a single-polarized antenna by leaving the unused polarity pin floating or grounded. Alternatively, it can be assembled at 45°, with respect to the horizontal plane, to be a dual-polarized antenna with slant (±45°) polarization.

For circular polarization, apply a 90° phase shift (introduced by a delay line or any similar mechanism) to the antenna feed ports.

The ADMV2228 comes in a compact, 3.25 mm × 3.25 mm land grid array [LGA] package and operates from a −55°C to +135°C operating TC range.
