PRE-RELEASE
(NR) N260 and N259 frequency bands. The ADMV2239 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 ADMV2239 has symmetric feeds and radiation patterns for both polarizations, allowing for rotation of the device on the board depending on the feeding scheme.
The ADMV2239 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 ADMV2239 comes in a compact, 2.25 mm × 2.25 mm land grid array [LGA] package and operates from a −55°C to +135°C operating TC range.
