Abstract
Conference Title: 2014 IEEE International Symposium on Antennas and Propagation & USNC/URSI National Radio Science Meeting Conference Start Date: 2014, July 6 Conference End Date: 2014, July 11 Conference Location: Memphis, TN, USA A tri-layer wide band FSS has been presented for hard-coated energy saving glass used in modern building architecture. Due to the presence of coating which blocks infrared signals and passes visible spectrum, there is an attenuation in the useful microwave signals as well, which is a drawback. Designing a band-pass FSS in the coating can be a solution to the problem. The proposed design is consisted of three FSS layers with a high-pass FSS sandwiched between two low-pass FSSs separated by glass layers. On average, it provides an improved transmission magnitude in -10 dB bandwidth of 1.4 GHz (0.62 - 2.02 GHz) which covers GSM 900/1800/1900 MHz, GPS, UHF TV, security bands etc. Due to complimentary FSSs structures, the infrared loss due to etching has been minimized and its efficiency is improved. It also provides 2.45 GHz WLAN security by confining signals to the interior of the building. The FSS design has a stable frequency response for both TE and TM polarizations up to 45°. It's performance is significantly enhanced in terms of average transmission magnitude improvement in -10 dB bandwidth, oblique incidence stability and loss/efficiency of infrared signal compared to the recently published research.
