A tulip-shaped antenna from Kyocera AVX is designed for ultra-wideband (UWB) applications, covering a frequency range of 6.0 GHz to 8.5 GHz. The surface-mount antenna is manufactured using laser direct structuring (LDS) technology, which enables a 3D pattern design. LDS allows the antenna to operate both on-board and on-ground, offering an omnidirectional radiation pattern with consistent 360° phase stability.
The antenna’s enhanced phase stability, constant group delay, and linear polarization are crucial for signal reconstruction, improving the accuracy of low-energy, short-range, and high-bandwidth USB systems. It can be placed anywhere on a PCB, including the middle of the board and over metal. This design flexibility surpasses that of off-ground antennas, which require ground clearance and are typically positioned along the perimeters of PCBs.
The tulip antenna is 6.40×6.40×5.58 mm and weighs less than 0.1 g. It is compatible with SMT pick-and-place assembly equipment and complies with RoHS and REACH regulations. When installed on a 40×40-mm PCB, the antenna typically exhibits a maximum group delay of 2 ns, a peak gain of 4.3 dBi, CW power handling of 2 W, and an average efficiency of 61%.
Designated P/N 9002305L0-L01K, the tulip antenna is produced in South Korea and is now available through distributors Mouser and DigiKey.
