Miniature Antenna Drops Ground Clearance Need
Leankon's 3 mm antenna mounts over the circuit board's ground plane, a shipped product for tight wireless designs.
Updated on Nov. 4, 2026 in Semiconductors
Leankon has launched LK1810701, a miniature 2.4GHz on-ground surface-mount antenna measuring 3 mm × 3 mm × 4 mm. The product is a commercial launch, so it is shipped rather than research-stage, though the stub gives no pricing or availability dates.
Why it matters
Conventional antennas need a cleared region of ground plane around them to resonate efficiently, and that requirement is a major design bottleneck in space-constrained devices. A compact part that can sit directly over the ground plane points toward denser wireless hardware without giving up that space.
The figures are the manufacturer's stated 2.4GHz operating frequency and 3 mm × 3 mm × 4 mm package size. No efficiency, gain, or benchmark results against a conventional antenna are given in the source material.
The players
Leankon
A company whose LK1810701 2.4GHz on-ground antenna is a miniature, laser-structured 3D component for space-constrained wireless devices.
The details
The antenna is built using 3D Laser Direct Structuring (LDS), in which a laser traces precise patterns onto a special plastic and those patterns are then made conductive to form the antenna. Its 3D spiral geometry is molded from Liquid Crystal Polymer (LCP), a high-performance plastic, and the spiral is hollow inside to reduce energy losses within the material. Because it comes in a form that automated machines can place, it can be assembled onto circuit boards with standard production equipment.
The Tech Race
The launch positions Leankon's part against the traditional ground-keep-out antenna approach that has long set the layout rules for compact radio hardware. No named competing product or research program is identified in the source material.
Engineers designing space-constrained wireless products could place the antenna directly over the ground plane, potentially simplifying board layouts. Availability, pricing, and sampling timelines are not stated in the source material.
The takeaway
Watch for independent efficiency measurements of the LK1810701 that compare its radiation performance against conventional ground-keep-out antennas. Those results would show whether the removal of the clearance region costs anything in signal quality.
