Methods and systems are disclosed for folded antenna structures that allow for receive and/or transmit antennas to be used for portable or other devices. The folded antennas described herein can be configured, for example, to fit the design constraints and considerations for portable devices. The folded antenna structures can be implemented using relatively flat flexible printed circuits (e.g., flex circuits) and can be placed in available spaces within the portable device, such as above or behind a battery, while still providing good performance characteristics. Still further, the folded antenna structures can be implemented on a printed circuit board and/or as part of plastic materials and pieces included as part of a portable device.
