Design and characterization of a tunable aperture coupled microstrip patch antenna with ferroelectric films

A reconfigurable aperture coupled microstrip patch antenna with beam steering capability on silicon

“…In comparison with the structure in [26], [28] our proposed structure provides almost similar performance, but this has the advantage of onchip integration, since this is in silicon substrate.…”

“…Reconfiguring the frequency using material properties is one of the best technique. Barium strontium titanate (BST) is one of the ferroelectric material which gives excellent tunability range [26].…”

“…At 0V BST has a permittivity of around 510 and at 40V it changes to 250. Using BST the tuning range can be obtained around 500MHz to 40GHz [26].…”

Ultrahigh frequency tunability of aperture-coupled microstrip antenna via electric-field tunable BST

“…Comparing with bulk BST, the BST film possesses a superior tunability and lower relative permittivity (ε r = 300-800), [6,9] however, the preparation methods, such as pulsed laser deposition, magnetron sputtering and metalorganic chemical vapor deposition, are too expensive to be used in the microwave industry. [10][11][12] In this study, low cost BST composite ceramics are prepared by solid state reaction process for fabricating FRC antennas. Some challenges will be encountered when fabricating an FRC antenna with BST slices.…”
