A rectangular reconfigurable, 1×8 linear array antenna has been designed and developed for tri-band, S, C and X-band applications. The antenna is excited along with the combination of PIN diodes to achieve the frequency and pattern reconfigurability. The design has been validated using a linear array fabricated on RT duroid 5880 substrate (ɛ r =2.2). The individual patch antenna consists of...
The nanoceramic Ba0.5Sr0.5 (CO0.8Fe0.2)1-x ZrxO3-δ (Barium Strontium Cobalt Iron Zirconate)BSCF powders have been synthesized by sol-Gel process using nitrate based powdered chemicals for SOFC applications, as these powders are more useful for Cathode of SOFCs. Ionic conduction, Adsorption and desorption rates are the major processes that control the electrode reactions. They contribute to the over...
A dual band reconfigurable Substrate Integrated Waveguide (SIW) cavity backed slot antenna is presented with dual states. A prototype of the SIW cavity backed slot antenna is fabricated and tested. PIN diodes have been used as a switching device to achieve the re-configurability with dual band operation. The SIW antenna has been tested in the outdoor test range and the measured and simulated characteristics...
