Main Question or Discussion Point
Hi I wonder if any one could advise how a radio wave would propagate around a metal object? Basically, I have a GPS antenna and due to mechanical issues the antenna is obscured by a mounting screw that sits in front of the antenna by about 2~3cm. I understand that the radio wave would become reflected/refracted/diffracted/scattered to some greater or lesser degree and is wavelength dependant. I wondered if any one could advise how much an effect this screw would have and advise any approximations or assumptions that could be made?
