Abstract—Detail numerical simulation, fabrication, and Nb^:_0&H@  
experimental measurement of a 2.4-GHz polarization-diversity Cbvl( (  
printed dipole antenna are presented for wireless communication G6VHl:e7z  
applications. Two orthogonal printed dipole antennas and each tg3JU\  
with a microstrip via-hole balun feeding structure are combined Z=8CbS).  
and fabricated on an FR-4 printed-circuit-board substrate. A eaP$/U D?  
p-i-n-diode circuit is used to switch and select the desired antenna [IA==B7  
polarization. In the antenna design simulation, a full-wave !Y(qpC:$  
method of a three-dimensional finite-difference time-domain Cfb-:e$0  
(FDTD) method is employed to analyze the entire structure `b'J*4|oGo  
of the printed antenna including the lumped elements of the Qs X59d  
polarization-selected p-i-n diode switching circuit. The Berenger A8(PI)Ic.  
perfectly matched layer absorbing-boundary condition is used rL3Vogw'e  
for the FDTD computation. Numerical and measured results of E'6P>6l5  
antenna radiation characteristics, including input standing-wave .: ;Hh~  
ratio, radiation patterns, and polarization diversity are presented. $%8n,FJ[
