Samsung has developed an antenna smaller than 1mm and a power amplifier that will make devices and radio stations smaller for 5G usage, the company has said.

The South Korean tech giant said it developed the ultra-small antenna by separating functions that can be attached separately to the case of the device.

It has also developed a power amplifier that amplifies wireless signals, which doubles the power output of previous high-frequency ones with significant less power consumption, the company said.

Devices and radio stations used for 5G demonstrations have been previously too big for commercialisation and this new technology overcomes that, it added.

5G uses ultra-high spectrum with a short range to secure speed that requires more radio stations than 4G, which means making them smaller is a crucial task for vendors.

The newly developed technology will be used for 5G radio stations for 28GHz spectrum designated by South Korea's Ministry of Science, ICT and Future Planning for testing.

The company began the development of 5G technology in 2011 and showed off a data transmission speed of 1Gbps in 2013.

In 2014, it showed a data transmission of 1.2Gbps in a moving car going at 110 km/h. Earlier this year, it demonstrated handover technology between ultra-high spectrum radio stations.
