Mobile wireless communications device comprising multi-frequency band antenna and related methods

A mobile wireless communications device comprising:

• a housing;
• and
• a multi-frequency band antenna carried within said housing and comprising
• a main loop conductor having a gap therein defining first and second ends of said main loop conductor, said main loop conductor including non-planar portions,
• a first branch conductor having a first end connected adjacent the first end of said main loop conductor and having a second end defining a first feed point,
• a second branch conductor having a first end connected adjacent the second end of said main loop conductor and a second end defining a second feed point, and
• a tuning branch conductor having a first end connected to said main loop conductor between the respective first ends of said first and second branches,
• at least one of said first, second, and tuning branch conductors comprising a tuning feature therein.

A method for making a mobile wireless communications device comprising:

• providing a housing;
• and
• positioning a multi-frequency band antenna within the housing and comprising
• a main loop conductor having a gap therein defining first and second ends of the main loop conductor,
• a first branch conductor having a first end connected adjacent the first end of the main loop conductor and having a second end defining a first feed point,
• a second branch conductor having a first end connected adjacent the second end of the main loop conductor and a second end defining a second feed point, and
• a tuning branch conductor having a first end connected to the main loop conductor between the respective first ends of the first and second branches.
