Abstract:
In an antenna apparatus, at least one choke in the form of a groove is arranged between a transmitting antenna and a receiving antenna. The choke functions to suppress the mutual electromagnetic coupling between the transmitting antenna and the receiving antenna. The depth of the choke is in a range from 0.15, to less than 0.225λ where λ is a wavelength of a carrier wave.
