Abstract
A mobile wireless communications device includes a housing and circuit board carried by the housing. Radio Frequency (RF) circuitry is mounted on the circuit board. A first antenna is supported by the circuit board within the housing and operatively connected to the RF circuitry and configured for cellular phone communications. A second antenna is supported by the circuit board within the housing and operatively connected to the RF circuitry and configured for WiFi communications. The second antenna comprises an inverted-F or monopole antenna having an opening gap that is pointed away from the first antenna.

1-25. (canceled)
A mobile wireless communications device comprising:
- a housing;
- circuitry within said housing;
- a first antenna within said housing and coupled to said circuitry for communications in at least one first frequency band;
- and
- a second antenna coupled to said circuitry for communications in at least one second frequency band;
- said second antenna comprising an inverted-F antenna defining an opening gap pointed in a direction within said housing away from said first antenna;
- said second antenna having an input impedance of between 30 to 75 ohms.
A mobile wireless communications device comprising:
- a housing;
- circuitry within said housing;
- a first antenna extending in a first direction within said housing and coupled to said circuitry for communications in at least one first frequency band;
- and
- a second antenna coupled to said circuitry for communications in at least one second frequency band;
- said second antenna comprising an inverted-F antenna defining an opening gap pointed in a second direction within said housing transverse to the first direction and away from said first antenna;
- said second antenna having an input impedance of between 30 to 75 ohms.
A method of making a mobile wireless communications device comprising:
- providing a housing with circuitry therein;
- forming a first antenna extending within the housing and coupled to the circuitry for communications in at least one first frequency band;
- and
- forming a second antenna coupled to the circuitry for communications in at least one second frequency band, the second antenna comprising an inverted-F antenna defining an opening gap pointed within the housing away from the first antenna, and the second antenna having an input impedance of between 30 to 75 ohms.
