Claim Text:
1. An antenna comprising: a monolithic flat metal conductor forming a first arm, an elongated loop including a gap, and a second arm, the first arm and second arm extending from endpoints of the elongated loop on opposite sides of the gap, the first arm connecting the elongated loop to a feed terminal and the second arm connecting the elongated loop to a ground terminal, an interface of the second arm with the ground terminal being proximate to the feed terminal, wherein: the elongated loop has substantially straight first and second sides oriented in a direction of a long axis of the elongated loop, the gap being on the first side of the loop, wherein the elongated loop folds back upon itself approximately 180° along the long axis of the elongated loop with the first and second sides being on opposite sides of a fold, the second side of the elongated loop has a first section with a smaller cross-sectional area than a second section, a transition in cross-sectional areas between the first and second sections being discontinuous, the first section being on a feed terminal side of the transition and the second section being on a ground terminal side of the transition, and a first distance from an interface of the first arm with the feed terminal, along the conductor forming the first arm, the elongated loop, and the second arm, back to the interface of the first arm with the feed terminal, is approximately equal to one-and-one-half of a wavelength corresponding to an operating frequency in a 5 GHz Wireless Local Area Network (WLAN) band.
