Internal Cellular and Bluetooth FPC Antenna | V1439-069-A-01

The VLG V1439-069-A-01 cellular Bluetooth antenna design combines internal FPC elements for a low-band cellular path and a 2.4 GHz Bluetooth path. It can be evaluated for connected vehicle equipment requiring these specific RF functions. Selection should follow the documented bands rather than a general full-band cellular description.

Key specifications and selection criteria

Keep the cellular range explicit

The reference main-antenna table lists 700–960 MHz. It does not establish performance across higher LTE bands. Before using the design with a modem, verify every required band and decide whether additional antenna paths or a different antenna version are needed.

Evaluate the Bluetooth path independently

The Bluetooth section lists 2400–2500 MHz, maximum VSWR of 2.5 and average efficiency of 49%. Check the required local coverage and the antenna’s position relative to nearby metal and other radios. The Bluetooth antenna is separate from the software and device-pairing functionality.

Retain realistic RF figures

The main path lists a maximum VSWR of 5.5 and average efficiency of 36%. These figures should be visible in the selection decision, rather than replaced with a generic low-VSWR or high-efficiency claim. Ask for the frequency plots and reference setup to understand the values.

Test the installed FPC layout

Plan the feed, antenna clearance and cable route in the final enclosure. Compare both radio paths with the device active, and check coexistence during transmission. Use the tested placement to control production assembly.

Frequently asked questions

Is this a full-band LTE antenna?

The supplied main-path data covers 700–960 MHz. Additional band data is needed before making a broader compatibility claim.

Why publish a relatively high VSWR limit?

Accurate limits help engineers judge suitability. Matching and radiated performance should be assessed together in the intended device.
