Abstract :
We present a Ka-band tightly coupled dipole array with micro electro-mechanical systems (MEMS) phase shifters directly integrated with the element feed structure. The dipole elements are printed on an alumina substrate with a twin coplanar waveguide (CPW) feed to ensure balanced feeding. An alternate feed structure in the form of Γ-matching circuit is also introduced to reduce the number of MEMS phase shifter required for the twin CPW feed.
