JAKARTA - The National Research and Innovation Agency (BRIN) is developing single-layer and multilayer microstrip antennas. This small antenna is developed for the needs of 6G technology.
BRIN Junior Researcher, Yohanes Galih Adhiyoga, explained that this antenna must be made as small as possible. That way, the antenna can be easily integrated into future mobile devices.
"We can't possibly have an antenna whose dimensions exceed the size of the mobile phone itself. Therefore, the antenna must be designed as small as possible so that it can be placed inside the device," said Yohanes, quoted on Friday, February 13.
This antenna was developed through a very long research process, from simulation, optimization, to fabrication in the laboratory. BRIN has prepared high-frequency measuring instruments up to 110GHz to test the performance of the antenna.
The initial phase of the development of this antenna is very important for the potential use of millimeter-wave frequencies in the country. The research team measured technical parameters and radiation patterns to ensure that the resulting signal remains stable.
In addition to mobile phones, BRIN is also developing special antennas for satellite communications or SATCOM. This antenna is developed to maintain a stable connection between satellites in orbit and stations on Earth.
This technology adopts a phased array system concept similar to Starlink's technology. The system allows the direction of the signal beam to move electronically without the need for physical movement on the antenna.
"The antenna is physically still silent, but from an electromagnetic point of view, the direction of the signal emission can move. This is important because low-orbit satellites have a fast movement so that the antenna must also be able to follow the movement of the satellite," explained Yohanes.
The development of this antenna is supported by a sophisticated laboratory infrastructure in the Bandung Science and Technology Area. Facilities such as an anechoic chamber and high-precision protolaser are used to ensure accurate research results.
