The field of wireless communications has been undergoing a revolutionary growth

in the last decade. This is attributed to the invention of portable mobile phones

some 15 years ago. The success of the second-generation (2G) cellular

communication services motivates the development of wideband third-generation

(3G) cellular phones and other wireless products and services, including wireless

local area networks, home RF, Bluetooth, wireless local loops, local multi-point

distributed networks (LMDS), to name a few. The crucial component of a wireless

network or device is the antenna. Very soon, our cities will be flooded with

antennas of different kinds and shapes. On the other hand, for safety and

portability reasons, low power, multi-functional and multi-band wireless devices

are highly preferable. All these stringent requirements demand the development of

highly efficient, low-profile and small-size antennas that can be made imbedded

into wireless products.
