Patent ID: 7327320

Claim:
A broadband antenna for transmitting and receiving the frequency range from about 800 MHz to about 9 GHz, comprising: a monopole antenna element extending in a longitudinal direction substantially parallel to and at a distance above a planar, electrically conductive base plate between two opposite ends of said antenna element, wherein said antenna element is electrically conductively connected at a first end to said base plate, said antenna element has a feed point at a second end thereof, which is electrically isolated from said base plate, wherein said antenna element is adapted to be connected to a radio-frequency device via said feed point; a coaxial plug connector arranged at a right angle to said base plate, wherein said coaxial plug connector is a connecting socket arranged on a lower face of said base plate near said feed point, wherein an outer conductor of said coaxial plug connector is electrically connected to said base plate such that an inner conductor of said coaxial plug connector is electrically connected through an opening in said base plate to said feed point of said antenna element, and said connection between said feed point and said inner conductor of said coaxial plug connector is detachable, and an electrically conductive connecting pin, which projects downwards at a right angle to said base plate and which is arranged at said feed point of said antenna element, said connecting pin being adapted to fit in a socket connected to said inner conductor of said coaxial plug connector.
