Abstract
The use of low emissivity windows degrades radio communication. This paperpresents design, manufacturing and test measurements for an energy savingwindow that is transparent to GSM, GPS and 3G radio wave frequencies.A frequency selective structure (FSS) is used in the metallic coating of thewindow to provide the needed transparency that ranges from 900MHz to2GHz. The periodic pattern used for the FSS is of the aperture type and theelements are hexagon loops. FSS simulations are performed using two dierentmethods, namely the mode matching technique and the Finite-DierenceTime Domain method. A frequency selective window is manufactured from acommercially available low emissivity glass. Measurements indicate that thefrequency selective window... (More)
