<p>A beam scanning plane antenna is formed by stacking a system connecting portion (104), a Rotman lens portion (103), and a beam scanning antenna portion (102) in order from bottom. The system connecting portion (104) is formed by stacking a fourth grounding conductor (14), a sixth dielectric (36), a connecting substrate (63) and a fifth dielectric (35) in order from bottom. The Rotman lens portion (103) is formed by stacking a third grounding conductor (13), a fourth dielectric (34), a Rotman lens substrate (62) and a third dielectric (33) in order from bottom. The beam scanning antenna portion (102) is formed by stacking a second grounding conductor (12), a second dielectric (32), a power feeding substrate (61), a first dielectric (31) and a first grounding conductor (11) in order from bottom. A plurality of antenna groups each constituted of an irradiating element (50), apowerfeeding line (40) and a first connecting portion (51) are formed on the power feeding substrate (61). The Rotman lens substrate (62) includes a Rotman lens pattern (8), a second connecting portion (52) and a third connecting portion (92).</p> |
