This is an "internal" antenna that can be used on 4G, 3G, GPRS/GSM or WiFi/Bluetooth modules that have a U.FL antenna connector.
Whereas using a U.FL-to-SMA adapter would allow you to connect a larger antenna to the outside of your finished product, this antenna is designed to be kept inside the enclosure of your product — hence it being called an internal antenna.
