Antenna apparatus and transmission and receiving apparatus using same

Abstract

An antenna apparatus such that a dielectric strip and a dielectric resonator are provided for form a primary vertical radiator, another dielectric strip is provided which is coupled to the dielectric strip to form a directional coupler, and a radiation beam is tilted by changing the relative position of the primary radiator with respect to the dielectric lens by displacing the primary vertical radiator in the direction coupler.

What is claimed is:  
     
         1 . An antenna apparatus comprising: 
 a dielectric lens having a focal plane; and    a primary radiator, the dielectric lens and primary radiator having a relative positional relationship,    wherein the dielectric lens and the primary radiator are arranged so that the relative position relationship of the primary radiator within the focal plane of the dielectric lens can be changed
