A Novel Reconfigurable Patch Antenna with Parasitic Patch

Abstract

In this paper, a novel frequency reconfigurable microstrip patch antenna with three parasitic patches has been proposed. This switchable band characteristics is achieved by introducing three PIN DIODES between the main patch and three parasitic patches. By different combination of PIN DIODES singl band, dual band and triple band characteristics can be achieved. FR4 Epoxy substrate with dielectric constant 4.4 and tangent loss 0.025 has been used. For the antenna simulation CST MW Studio software has been used.
