Leankon Launches Miniature 2.4GHz On-Ground Antenna
The compact LK1810701 antenna can be mounted directly above a circuit board's ground plane without a traditional keep-out zone.
Updated on Nov. 4, 2026 in Semiconductors
Leankon has launched the LK1810701, a miniature 2.4GHz on-ground SMD antenna measuring 3 mm × 3 mm × 4 mm. It is designed to be placed on a circuit board using automated machines.
Why it matters
Conventional antennas typically require ground keep-out regions to establish resonance and maintain acceptable radiation efficiency. For space-constrained electronics, that clearance requirement is often a significant design bottleneck, which this compact form factor aims to address.
The LK1810701 is specified at 2.4GHz and measures 3 mm × 3 mm × 4 mm, figures reported by the manufacturer rather than independent testing. The extraction does not include radiation efficiency measurements or a direct comparison against conventional antenna clearance requirements.
The players
Leankon
Leankon is the manufacturer that launched the LK1810701 miniature on-ground antenna.
The details
The antenna uses 3D Laser Direct Structuring, in which a laser creates precise patterns on a special plastic that are then made conductive to form a 3D spiral-shaped antenna. It is built from Liquid Crystal Polymer with a hollow internal structure, which reduces energy losses, and uses a high-Dk material.
The Tech Race
The LK1810701 departs from the conventional PCB antenna approach, which has long required keep-out regions in the ground plane to achieve resonance. Its 3D spiral LDS design positions it as an alternative for compact devices where that clearance has constrained board layout.
For device makers, the antenna's compact footprint and lack of a ground keep-out zone could free board space in small electronics. Engineers evaluating it should verify performance against their own layout and regulatory requirements.
The takeaway
Compact antennas that avoid ground keep-out zones could change how engineers approach space-limited board designs. Evaluating manufacturer specifications against real-world layouts remains essential before adoption.
