1.Introduction

The PC14.03.3000D is a high performance wireless antenna for internal use in Wi-Fi or

WLAN equipment worldwide. Omni-directional gain across both bands ensures

constant reception and transmission. Its compact size and high performance make it

ideal for integration into today’s devices.

Many module manufacturers specify peak gain limits for any antennas that are to be

connected to that module. Those peak gain limits are based on free-space conditions.

In practice, the peak gain of an antenna tested in free-space can degrade by at least

1 or 2dBi when put inside a device. So ideally you should go for a slightly higher peak

gain antenna than mentioned on the module specification to compensate for this

effect, giving you better performance.

Upon testing of any of our antennas with your device and a selection of appropriate

layout, integration technique, or cable, Taoglas can make sure any of our antennas’

peak gain will be below the peak gain limits. Taoglas can then issue a specification

and/or report for the selected antenna in your device that will clearly show it

complying with the peak gain limits, so you can be assured you are meeting regulatory

requirements for that module.

For example, a module manufacturer may state that the antenna must have less than

2dBi peak gain, but you don’t need to select an embedded antenna that has a peak

gain of less than 2dBi in free-space. This will give you a less optimized solution. It is

better to go for a slightly higher free-space peak gain of 3dBi or more if available. Once

that antenna gets integrated into your device, performance will degrade below this

2dBi peak gain due to the effects of GND plane, surrounding components, and device

housing. If you want to be absolutely sure, contact Taoglas and we will test. Choosing

a Taoglas antenna with a higher peak gain than what is specified by the module

manufacturer and enlisting our help will ensure you are getting the best performance

possible without exceeding the peak gain limits.

Cable and connector are fully customizable.
