Small-size broadband multi-element antenna for RF/wireless systems

We present a small-size broadband antenna specifically designed for integration with RF/wireless communication systems. The antenna is built on a printed circuit board and fed by a coplanar waveguide (CPW) to allow further easy integration with active and passive components of the communication system. The compact architecture of the antenna is suitable for multi-element scenarios for diversity implementations. Theoretical and experimental results showing impedance and radiation characteristics for both single- and multi-element antenna are given and discussed.
