The Phone (3) runs Nothing OS 3.5, based on Android 15, but will get a 4.0 upgrade later in 2025, plus five major Android ...

This paper presents a compact planar design of 2-D Butler matrix steering the beam of a patch antenna array for D-band frequencies. The stripline Butler matrix feeding network is beneath the ...

A 2-D Butler matrix (BM) in uniplanar configuration for designing multibeam array antenna (MAA) is proposed using substrate integrated waveguide (SIW) technology. Firstly, a novel topology for ...
