Abstract:
A steerable antenna includes an radiating antenna element and parasitic antenna elements. Each of the parasitic antenna elements is provided with a pair of PIN diodes. On each of control lines connecting the PIN diodes to a controller, inductors are provided at predetermined intervals on portions of the control line electromagnetically coupled to another steerable antenna. The intervals for providing the inductors is set to such a length that substantially no resonance occurs in a section of the control line between the inductors at an operating frequency of the steerable antenna.
