20100184388 | MOBILE WIRELESS COMMUNICATIONS DEVICE COMPRISING MULTI-FREQUENCY BAND ANTENNA AND RELATED METHODS - A mobile wireless communications device may include a housing and a multi-frequency band antenna carried within the housing. The multi-frequency band antenna may include 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, and 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. The antenna may further include 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. | 07-22-2010 |
20090066586 | MOBILE WIRELESS COMMUNICATIONS DEVICE INCLUDING MULTI-LOOP FOLDED MONOPOLE ANTENNA AND RELATED METHODS - A mobile wireless communications device may include a portable housing, a printed circuit board (PCB) carried within the portable housing, and wireless communications circuitry carried by the PCB within the portable housing. Furthermore, a folded monopole antenna may be coupled to the wireless communications circuitry. The folded monopole antenna may include a dielectric body having a generally rectangular shape defining a bottom portion adjacent the PCB and a top portion opposite the bottom portion. The antenna may also include a conductive trace having a bottom loop adjacent the bottom portion of the dielectric body, a top loop adjacent the top portion of the dielectric body, and an intermediate wrap-around section extending around the dielectric body and between the bottom and top loops. | 03-12-2009 |
20090058734 | MOBILE WIRELESS COMMUNICATIONS DEVICE INCLUDING A FOLDED MONOPOLE MULTI-BAND ANTENNA AND RELATED METHODS - A mobile wireless communications device may include a portable housing, a printed circuit board (PCB) carried within the portable housing, and wireless communications circuitry carried by the PCB within the portable housing. The device may also include a folded monopole antenna assembly coupled to the wireless communications circuitry. The folded monopole antenna assembly may include a dielectric body adjacent the PCB and having a generally rectangular shape defining opposing top and bottom faces, opposing first and second end faces, and opposing first and second side faces. The antenna may also include a conductive trace coupled to the wireless communications circuitry and having a first end section extending along the first end face, a second end section extending along the second end face, and an intermediate section extending along the top, bottom, first side and second side faces. | 03-05-2009 |
