COTS Embedded Quad Band GSM antennas - RF Cafe Forums

The original RF Cafe Forums were shut down in late 2012 due to maintenance issues - primarily having to spend time purging garbage posts from the board. At some point I might start the RF Cafe Forums again if the phpBB software gets better at filtering spam.

Below are the old forum threads, including responses to the original posts.

I am looking for a small quad band GSM antenna. I have found a couple via a quick internet search (example the Taoglas PC-27). However, with all the antennas I have found thus far there is no recomendation regarding how best to fit the antenna with respect to the ground 'lump' you have.

Does anyone have any experience with the Taoglas PC-27 ? Alternatively a recomendation for another Quad band GSM antenna with some guidance on fitting?

I have the necesarry kit (VNA, anachoic chamber etc) to go down the empirical road for placement of the antenna but it would be nice to have some basic starting point recommendations!

Steve

Greetings,

It must be made clear that "embedded" and "COTS" almost conflict with each other... Off the shelf implies that the implimentation should be easy, while embedded implies integrated within a system.

I work with ceramic and PCB antennas all the time as an FAE. The datasheet for this and other PCB antennas typically describe free-space results. Not many recommendations are provided from the manufacturers on placement - since a radiator placed inside ANYTHING will behave differently with respect to impedance and radiation patterns.

Puse Engineering offers a wide variety of antenna products very similar to Toaglas and Antenova. IF you need more information on an equivalent, to this part number, go to the following website and request further info on the W3501 antenna. This antenna (not on the website) is a stand-alone radiator similar to the Taoglas antenna.

If you have very low volume (available space for the antenna), then look for the W3502 - which takes advantage of the PCB that it is conencted to (via IPEX / U.FL connector).

Hope this helps!

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...
