Description
S Murugeswari, with five colleagues, presents a 2026 design for a tiny two-port antenna for 5G phones and wearables. The antenna must work at millimetre waves, where signals carry much data but need careful design at small size. The board is only about twelve millimetres long, among the smallest in its class.
A meandering slot stretches the electrical path without growing the board, and the antenna works in three bands between about 26 and 38 gigahertz. Gain held between 9.3 and 9.7 decibels across those bands. The two ports stayed well apart, with cross-talk at minus 20 decibels and a match score below 0.01. Tests on a layered hand model showed radiation absorbed by tissue stayed within safety limits. Lab measures matched the computer runs closely.
