Abstract

When a beam is formed in a direction at a switching point of microstrip array panels, two microstrip array panels associated with the switching point are used and a phase shift due to arrangement of the panels is compensated by a pre-set phase shifter so that sufficient gains can be secured for omni directions including boundary directions of the array panels in which very small gains have been obtained previously.
