Apparatus and methods for wireless communications antenna included within a wearable electronic device

An apparatus, comprising:

• a housing having a top portion and a bottom portion, the top portion of the housing including an antenna element;
• a printed circuit board (PCB);
• a metal frame having a first coupler and a second coupler, the PCB being disposed between and not conductively coupled to the housing and the metal frame, the PCB conductively coupled to the antenna element;
• and
• a band having a first end portion and a second end portion, the first end portion of the band being conductively coupled to the metal frame when removably coupled to the first coupler of the metal frame, the second end portion of the band being conductively coupled to the metal frame when removably coupled to the second coupler of the metal frame,
• the antenna element, the metal frame, the first end portion of the band and the second end portion of the band collectively defining an antenna having an antenna profile when the antenna is operational,
• the metal frame including a cut-out portion pre-selected to tune a first peak magnitude of the antenna when the antenna is operational, when the first end portion of the band is removably coupled to the first coupler of the metal frame, and when the second end portion of the band is removably coupled to the second coupler of the metal frame, and
• the antenna having a second peak magnitude when the antenna is operational, when the first end portion of the band is not coupled to the first coupler of the metal frame, and when the second end portion of the band is not coupled to the second coupler of the metal frame,
• the first peak magnitude being different from the second peak magnitude.

An apparatus, comprising:

• a band having a first metal coupler, a second metal coupler and an elongate material disposed between the first metal coupler and the second metal coupler,
• the first metal coupler and the second metal coupler each sized and configured to be removably coupled to an electronics module having a printed circuit board (PCB) and an antenna element conductively coupled to the PCB, the PCB and the antenna element being disposed between a housing and a metal frame,
• the antenna element, the metal frame, the first metal coupler and the second metal coupler collectively defining an antenna having an antenna profile when the antenna is operational and when the band is removably coupled to the electronics module,
• the antenna having a first peak magnitude when the antenna is operational, when the first end portion of the band is removably coupled to the first coupler of the metal frame, and when the second end portion of the band is removably coupled to the second coupler of the metal frame,
• the antenna having a second peak magnitude when the antenna is operational, when the first end portion of the band is not coupled to the first coupler of the metal frame, and when the second end portion of the band is not coupled to the second coupler of the metal frame, the first peak magnitude being different from the second peak magnitude.

A method, comprising:

• transmitting an electromagnetic signal from an antenna element coupled to a top portion of a housing;
• and
• electrically coupling the antenna element to (1) a metal frame having a first coupler and a second coupler, (2) a first end portion of a band, and (3) a second end portion of the band,
• the antenna element not being directly coupled to the metal frame,
• the first end portion of the band conductively coupled to the metal frame and removably coupled to the first coupler of the metal frame, the second end portion of the band conductively coupled to the metal frame and removably coupled to the second coupler of the metal frame,
• the electromagnetic signal having a first peak magnitude after the electrically coupling and having a second peak magnitude before the electrically coupling, the first peak magnitude being different from the second peak magnitude.
