Abstract
A wireless communication device includes an antenna for wireless communication with a remote interrogator. Several embodiments are disclosed to increase the options available to designers of wireless communication devices. In some embodiments, the antenna is a quarter wavelength long with one end of the antenna being grounded to provide desired impedance matching characteristics. The position of the ground plane relative to the antenna is also varied between embodiments. The connection from a wireless communication chip to the antenna is also varied between embodiments to provide alternate structures.
