Abstract (en)
[origin: WO02087015A1] In order to create a compact antenna block a corner-shaped support is provided with a radiating area on an upper surface thereof and a transition area is provided on an underlying surface. The transition area is characterized in that it is triangular. The angle of the triangle forms a connection point for the antenna. The tapered part of the corner-shaped support is fitted with a pole enabling it to be lifted above the plane of the circuit to which the antenna block is connected, whereby the transition area extends gradually above said plane, the upper radiating area being substantially parallel to said plane. As a result the impedance of the antenna can be regulated more easily in such a way that it is continuously constant and the reflection coefficient is improved.
