Abstract

Engineering Engineering, Electrical & Electronic Optics Physical Sciences Science & Technology Technology
A single-layer, bandpass, active FSS is presented. It shows good angle of incidence stability for TE incidence, at the operating frequency of 2.45 GHz. It is based on circular loop aperture with each unit cell having four PIN diodes. A novel method for dc biasing is used. About 12 dB average variation in transmission loss, between ON and OFF states, has been experimentally achieved at 2.45 GHz. (C) 2008 Wiley Periodicals, Inc.
