As Bluetooth®, WLAN, and IoT products continue to become smaller and more highly integrated, antenna designers must address limited PCB space, RF performance degradation, and interference from nearby components. Maintaining reliable wireless performance within a compact mechanical structure has become a major challenge for product development teams.
The OneWave WAN038070D2452SHR8 is a vertical chip antenna designed for 2.4GHz Bluetooth® and WLAN applications. Its narrow standing structure occupies a PCB area of only 8.00mm × 1.65mm, with a standing height of 7.00mm.
By shifting part of the antenna structure from the horizontal PCB surface into the vertical direction, the device helps preserve valuable board area for processors, power-management components, sensors, connectors, and other circuitry.
With 4.49dBi peak gain, bandwidth greater than 120MHz, a wide operating-temperature range, and SMT compatibility, the WAN038070D2452SHR8 provides a compact antenna solution that balances RF performance, board-space efficiency, and production readiness.
Conventional chip antennas installed in a flat orientation can occupy a significant amount of PCB length and width. As more components are integrated into compact wireless devices, finding sufficient board space for the antenna and its required clearance area becomes increasingly difficult.
The WAN038070D2452SHR8 features the following mechanical dimensions:
● PCB mounting area: 8.00mm × 1.65mm
● Standing height: 7.00mm
Its narrow 1.65mm mounting width allows the antenna to be positioned along the edge of a PCB or within a narrow layout area. This can reduce interference with the placement of other ICs and components.
The vertical configuration is particularly suitable for products with limited board area but sufficient internal height to accommodate a 7.00mm standing structure.
Reducing antenna size often requires tradeoffs among gain, bandwidth, and efficiency. Despite its compact footprint, the WAN038070D2452SHR8 provides a peak gain of 4.49dBi, offering competitive RF performance for 2.4GHz Bluetooth® and WLAN products.
The peak-gain performance can support effective signal transmission and reception in the intended radiation direction, giving engineers greater flexibility when designing compact wireless systems.
Actual communication range and RF performance will depend on the PCB size, ground structure, product enclosure, battery, display, cables, connectors, and nearby metal components. Final tuning and validation should therefore be completed using the actual PCB and product enclosure.
The WAN038070D2452SHR8 provides bandwidth greater than 120MHz for 2.4GHz wireless applications.
A wider antenna bandwidth provides additional design margin and can help reduce the impact of resonant-frequency shifts caused by changes in PCB size, enclosure material, component placement, and surrounding structures.
For systems that integrate both Bluetooth® and WLAN functions, the available bandwidth provides greater flexibility when developing a shared 2.4GHz antenna architecture.
Potential applications include:
● Bluetooth® wireless modules
● 2.4GHz WLAN devices
● Smart-home controllers
● IoT sensor nodes
● Industrial wireless-control equipment
● Wireless gateways
● Handheld and embedded devices
● Space-constrained communication terminals
The WAN038070D2452SHR8 supports an operating-temperature range from -40°C to +110°C, allowing it to address industrial equipment, outdoor products, and embedded systems operating under varying thermal conditions.
The antenna supports a maximum input power of 4W, providing flexibility for different 2.4GHz RF architectures. The actual input-power limit should be evaluated according to the latest manufacturer datasheet, impedance-matching condition, ambient temperature, and complete-system design.
Its wide-temperature capability expands its potential use beyond general consumer electronics to industrial and embedded wireless products.
Integrating a chip antenna involves more than simply mounting the component on the PCB. Ground-plane dimensions, feed-line routing, enclosure materials, and nearby components can all affect antenna impedance and resonant frequency.
The WAN038070D2452SHR8 is supported by a suggested matching circuit, giving engineers a practical starting point for RF implementation. Matching-component values can then be adjusted based on the final PCB layout and product enclosure.
The recommended matching architecture can help:
● Reduce initial antenna-circuit development time
● Accelerate impedance matching and frequency tuning
● Lower first-design implementation risks
● Improve prototype and production-validation efficiency
The antenna is SMT ready and RoHS compliant, supporting automated assembly and volume manufacturing.
The OneWave WAN038070D2452SHR8 combines a vertical mechanical structure, 4.49dBi peak gain, bandwidth greater than 120MHz, wide-temperature operation, and SMT production compatibility in a compact footprint.
For development teams designing Bluetooth®, WLAN, smart-home, industrial IoT, or embedded wireless products, the WAN038070D2452SHR8 provides an antenna option that balances PCB-space efficiency, RF performance, and production readiness.
