Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
140 words
A unidirectional antenna arrangement including a ground conductor plane (4), and a radiating conductor plane (5), each plane (4) (5) being arranged on a side of the dielectric substrate (g) which is opposite to the side on which the other is arranged, and a connecting conductor plane (7) which is connected at one edge to an edge of the radiating conductor plane (5) and at the opposite edge to the ground conductor plane (4) in order to connect together the radiating conductor plane (5) and the ground conductor plane (4), characterised in that there is further provided a unipole antenna (6) which is placed on the radiating conductor plane (5) at or adjacent to a point on the edge of the radiating conductor plane (5) that is opposite to the edge which is connected to the connecting conductor plane (7).
Claim 2
Dependent Claim
29 words
An antenna arrangement as claimed in claim 1 characterised in that the unipole antenna (6) is placed substantially on an axis of symmetry of the radiating conductor plane (5).
Claim 3
Dependent Claim
36 words
An antenna arrangement as claimed in claim 1, characterised in that there is further provided a power feeding means (8) whose outer and centre conductors are connected to the ground and radiating conductor planes (4,5) respectively.
Claim 4
Dependent Claim
31 words
An antenna arrangement as claimed in claim 3, characterised in that the length of the unipole antenna (6) is one quarter of the wavelength of the frequency used by the antenna.
Claim 5
Dependent Claim
20 words
An antenna arrangement as claimed in claim 3 characterised in that the unipole antenna (6) includes a bent unipole (17).
Claim 6
Dependent Claim
29 words
An antenna arrangement as claimed in claim 5 characterised in that the bent unipole is substantially shaped in the form of a letter L at the tip end thereof.
