: : Dear all,

: Just curious, what do you consider poor return loss? How are you measuring it? If I'm not mistaken these are the type of antennae used in cell phones, pagers etc. There are some major league techno companies applying their resources toward building these inverted planars, can you build one a home? Like I said, no help, just curious. Good Luck
