Abstract :
A radiation pattern varying technique using short-circuited coaxial structure at a feed point of the antenna is proposed. Short-circuited structure makes it possible to decrease the antenna gain for short-circuited side, and increase for the opposite side. The radiation pattern variance was experimentally observed at broad bandwidth. A radiation pattern variable antenna with diode SW is also demonstrated
