SIM900 Module with Surface mount antenna

时间:04-05 整理:3721RD 点击:
Can someone suggest me if you know any surface mount low cost antenna solution for GSM module [1]
(SIM900 module in my case). I will confirm the bands it needs to support. But at the moment you may think about an all band (something
like penta band) antena.

Questions:
1. In my opinion a surface mount antenna maybe difficult to use than the external SMA mount antenna? I mean difficult in terms that it may
require me to adjust tunning components (such as values of series inductor etc)?

2. How do you compare the external Antenna and surface mount antenna for GSM? Do you think performance of antennas having SMA connectos [2] and those which are about 1.5 inch in length perform will be much better?

3. Will i need an any sort of RF Amplifier if I use surface mount antenna with a GSM module which is actually meant to work with
external antenna?

I have been using ANTENOVA A10340 antennae without issue for a personal tracker unit.

Although I have a PI RC matching circuit it is only using a 0R resistor without the caps as the stripline was calculated to 50 ohms.
