First Claim
Patent Images
1. A mobile wireless communications device, comprising:
- a housing having an upper and lower portion;
a circuit board carried by the housing and including radio frequency (RF) circuitry;
a first antenna supported by the circuit board at the lower portion within the housing and operatively connected to said RF circuitry and configured for cellular phone communications; and
a second antenna supported by the circuit board within the upper portion of the housing and operatively connected to said RF circuitry and configured for WiFi communications, wherein said second antenna comprises an inverted-F antenna having a substantially rectangular configuration in plan and upper edge forming an opening gap that is pointed away from the first antenna for isolating first and second antennas from each other said second antenna including a lower edge and a feeding point and grounding point at opposite corners of the lower edge wherein mutual coupling due to harmonics between first and second antennas is reduced.
