| 摘要 | 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 antenna, the first antenna configured to provide a first resonant mode. The multi-band antenna also includes a second antenna parasitically coupled to the first antenna to provide additional resonant modes of the multi-band antenna. | ||

| 主权项 | 1. A multi-band antenna comprising: a single radio frequency (RF) input; a first antenna directly coupled to the single RF input, wherein the first antenna is configured to provide a first resonant mode of the multi-band antenna; and a second antenna parasitically coupled to the first antenna, wherein the second antenna is configured to provide a plurality of resonant modes of the multi-band antenna, wherein the second antenna is a T-monopole antenna comprising: a base coupled to ground;a first arm extending out from a first side of the base;a second arm extending out from a second side of the base; anda folded arm extending back towards the second side of the base from a distal end of the second arm. | ||
