Abstract:
Methods and systems for extending a bandwidth of a multi-band antenna of a user device are described. A multi-band antenna includes a single radio frequency (RF) input coupled to a first loop antenna, the first loop antenna configured to provide a first resonant mode. The multi-band antenna also includes a second antenna parasitically coupled to the first loop antenna to provide additional resonant modes of the multi-band antenna. The second antenna is a T-monopole antenna with a base coupled to the ground plane, a first arm extending out from a first side of the base, a second arm extending out from a second side of the base and a folded arm extending back towards the second side of the base from a distal end of the second arm.
