Abstract
The invention relates to an antenna system, which comprises a transmitter component (1, 2, 3, 4), a reception component (4, 3, 10, 11, 12), and an antenna (5) connected to these. According to the invention, the antenna (5) is arranged to connect to different connection points (6, 7, 8) of the transmitter (1, 2, 3, 4) or the reception component (4, 3, 10, 11, 12).
Claims15
Antenna system, which comprises
- a transmitter component (1, 2, 3, 4),
- a reception component (4, 3, 10, 11, 12), and
- an antenna (5) connected to these,
- characterized in that
- the antenna (5) is arranged to connect to different connection points (6, 7, 8) of the transmitter (1, 2, 3, 4) or the reception component (4, 3, 10, 11, 12).
System according to any of the above Claims, characterized in that the system comprises power-measuring means (30) for measuring the power fed to the antenna (5).
Method in connection with an antenna, in which method
- electrical power is fed to the antenna (5),
- the radiation power produced by the antenna (5) is regulated,
- characterized in that
- the radiation power produced by the antenna (5) is regulated by altering the electrical-power connection point (6, 7, 8) in the antenna (5).
Method according to any of the above claims, characterized in that the antenna (5) is tuned electrically using an electrically variable capacitor (9) connected in parallel to it.
Method according to any of the above claims, characterized in that the connection point is adjusted with the aid of an electrically controllable switch (4).
Method in connection with an antenna (5), in which method
- electrical power is received from the antenna (5),
- the noise of the receiver (12) is minimized,
- characterized in that
- the noise of the receiver is minimized by altering the electrical-power connection point (6, 7, 8) in the antenna (5).
Antenna (5), which antenna comprises,
- a conducting surface (20),
- a connection point (21) formed on the conducting surface, and
- a signal-feed conductor (24) connected to the connection point (21),
- characterized in that
- several connection points (21, 22), which can be selected one at a time as the connection point of the antenna, are arranged on the conducting surface (20).
Antenna (5) according to any of the above Claims, characterized in that it is a PATCH antenna.
Antenna (5) according to any of the above Claims, characterized in that it is a folded PATCH antenna.
