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

A Barium Strontium Titanate (BST) based reconfigurable Aperture-coupled patch antenna on high resistivity silicon substrates with beam steering capability using PIN diodes has been proposed in this paper. For low dielectric constant region in silicon substrate, Micromachined technique is used. Varying voltage across BST layer changes its permittivity thereby tunable frequency is achieved and switching p-i-n diodes will steer the beam. A Novel structure is proposed which gives high directivity (>; 6 dB), Good gain (>; 5 dB), low VSWR (1.5), low control voltages (<;80V) & 60° HPBWS.
