CM.02.03F21.02806 Datasheet, PDF (2/9 Pages) Taoglas antenna solutions – Boosts coverage and data-rate performance of following communication systems

1. Introduction
Taoglas Ceiling Mount Antenna CM.02 is a wideband antenna solution, 700 MHz to 6GHz,
covering all cellular, LTE, Wi-Fi and WiMAX applications in one antenna. The antenna has
high peak gain and efficiency across all bands enabling very wide coverage areas and
high speed data rates. The radiation pattern has excellent Omni-directional properties at
all frequencies, a unique feature of this wide-band antenna compared to other designs in
the market which tend to have nulls at certain bands. This antenna would provide all CPE
and Hotspot needs literally “under one roof”.
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
