Abstract. Thorough survey of open literature shows that the in recent years, the major jj{:=lZB  
fraction of research on microstrip and printed antennas is devoted to developing new 2xNR=u`  
design to improve antenna bandwidth along with other figures of merit. The recent &]TniQH  
trends are also some what different from those of last two decades. Some developments :Qa*-)rs  
in allied branches like, MIC's and printed circuits, are now being investigated to ^T&{ORWz  
antenna applications and those are discussed in a bri .. W>jKWi,{
