    Hi, We are trying to build a mobile device -which sends sensor data to database over GSM- for the first time. We are using SimCom Sim900R Dual band (900-1800 MHz) GSM module. We developed our circuitry on board using external GSM antenna, and now we want to build a compact design on PCB, which requires an embedded antenna solution. To do this, we have to find a solution for embedded Dual band GSM antenna. We can use small external Ceramic ...
