Patent ID: 6940470

Claim:
Antenna device, comprising: a dielectric substrate board ( 10 ), dipole means ( 16 ) formed on said substrate board ( 10 ), and reflector means ( 70 , 72 ) having first and second reflective surfaces ( 50 , 52 ) which are aparallel to each other, define a first angle (α) between each other and are formed on a single reflector member ( 70 , 72 ), whereby a positional relationship between said substrate board ( 10 ) and said reflector means ( 70 , 72 ) is such that said substrate board ( 10 ) and a vertex of said first angle (á) substantially lie in a same plane (M) and said first and second reflective surfaces ( 50 , 52 ) lie on opposite sides of said plane (M), a second angle (β) defined between said substrate board ( 10 ) and said first reflective surface and a third angle (γ) defined between said substrate board ( 10 ) and said second reflective surface being different from zero each; said reflector member having a slot ( 60 ) substantially at said vertex, with said substrate board ( 10 ) extending through said slot.
