Antenna

摘要

A curved inverted-L and F antenna is disclosed. In a preferred embodiment a curved inverted-F antenna 300 comprising a capacitative line 206 and inductive stub 204 is disposed above a correspondingly curved ground plane 308. Preferably, the separation between the capacitative line 206 and ground plane 308 is substantially constant and of the order of one tenth of the wavelength of the operating frequency of the antenna. Suitably the short circuit element of the antenna and the feed track 402 are non-parallel which has the effect of improving the radiated field in a short circuit direction.
