Abstract (en)
[origin: EP0375416A2] A plane slot antenna including a peripheral conducting surface (11), a central conducting surface (13) provided in the peripheral conducting surface with a space (21) in between, and a plurality of coaxial lines (20, 30). The cores (21, 31) of the coaxial lines are connected to the central conducting surface at different points thereof and outer skins (22, 32) of the coaxial lines are connected to the peripheral conducting surface. The antenna further includes a switch (40) provided between the coaxial lines and a signal receiver so that the switch changes a connection between one of the coaxial lines and the signal receiver so that the antenna receives signal of best possible strength and phase.
