Ligen’s millimeter-wave antenna modules target the low-Earth-orbit satellite market

Ligen Technology says more than a decade of millimeter-wave research is finally moving into commercial delivery, with satellite, communications and defence projects entering new stages.

Chairman Chang Shu-wei said the rapid growth of artificial intelligence has made network resilience a national-security priority. Demand is rising for connectivity across mobile communications and multi-orbit satellite infrastructure, while defence projects are moving from verification toward delivery and mass production.

Ligen has completed product development and customer validation for its millimeter-wave phased-array antenna modules. The company is now advancing three markets: broadband communications, defence communications and multi-orbit satellites. Chang said satellite products could begin generating orders and shipments within a year.

The rapid growth of AI has made network resilience a national-security priority.

He linked the company’s prospects to the development of AI, 6G and satellite communications. The International Telecommunication Union established 6G performance indicators in 2026, covering six areas including AI, immersive communications and integrated sensing. Ligen views millimeter-wave and phased-array technology as key to high-frequency, high-bandwidth communications and precise beam control in 5G, 6G, satellite systems and defence radar.

In fixed wireless access, Ligen is participating in large millimeter-wave projects for telecom operators in emerging markets and is accelerating field trials ahead of mass production. Market observers believe India could be among its targets. In defence communications, the company has entered the supply chain for AESA phased-array radar and communications modules in the Middle East and has reached equipment delivery and testing. It is also working with US company Comtech on a “One Modem, One Antenna” terminal for switching between satellite orbits. End-to-end tests with several in-orbit satellites have been completed, while local contract manufacturing discussions continue.

Antenna modules made up 5.62% of revenue in 2024 and 30.30% in 2025. Ligen said the share continued to rise in 2026 and aims to push it above 50% in 2027.

We need more jet drones, we need cheap missiles, we need missiles with artificial intelligence. Otherwise, there is no way to reach an agreement with Putin... He understands only force.
