Multi-Band Embedded Antenna I

Custom

An integrated antenna combining Cellular, GNSS, and Wi-Fi.

Optimized for compact design by minimizing inter-antenna interference, contributing to reduced assembly time.

Features

1. Optimized for Compact Devices

From the initial design stage, we propose the antenna keep-out area and optimize antenna geometry considering surrounding components. Our proprietary antenna element structure enables stable performance (gain, radiation pattern, and radiation efficiency) even under ground plane conditions close to metal surfaces. The thermally bonded antenna element structure allows multiple antenna elements to be integrated into a single molded component.

2. Supports a Wide Frequency Range

Recent wireless devices are required to support multiple standards and frequency bands, including Wi-Fi, Bluetooth, LTE, and GNSS. Multi-Band Embedded Antenna is one of the optimal solutions, as it can incorporate multiple feed points to support multi-band operation.

Frequency tuning is available to match target frequency bands such as 400 MHz and 920 MHz.

3. Supports Lower Production Volumes than MID or LDS

Manufacturing methods such as MID and LDS, which directly form antenna elements on resin components, typically require large production volumes of at least 100,000 units. STAF Corporation’s Multi-Band Embedded Antenna supports production volumes starting from tens of thousands of units. Please contact us for details.
