Abstract
An apparatus for indicating a direction of a radio transmission is described. The apparatus includes at least one vector detection device including two or more antennas and an attenuating material between at least one of the antennas and a source of a radio transmission. The attenuating material is arranged to vary an amount of attenuation with an angle of the source with respect to at least one of the antennas. The apparatus is configured to generate a signal indicating a direction of the radio transmission by comparing received signal strengths from the two or more antennas.
Claims20
An apparatus for indicating a direction of a radio transmission, comprising:
- at least one vector detection device comprising two or more antennas, an attenuating material between at least one of the antennas and a source of a radio transmission, and a shielding material configured so that the radio transmission goes through the attenuating material or is shielded by the shielding material, wherein the attenuating material is arranged to reduce the signal strength of the radio transmission corresponding to an angle of the source with respect to the at least one of the antennas, and wherein the apparatus is configured to generate a signal indicating a direction of the radio transmission by comparing received signal strengths from the two or more antennas.
A method for indicating a direction of a radio transmission, comprising:
- receiving a radio transmission by at least one vector detection device of an apparatus, wherein the at least one vector detection device comprises two or more antennas, an attenuating material between at least one of the antennas and a source of the radio transmission, and a shielding material configured so that the radio transmission goes through the attenuating material or is shielded by the shielding material, and wherein the attenuating material is arranged to reduce the signal strength of the radio transmission corresponding to an angle of the source with respect to at least one of the antennas;
- comparing, by the apparatus, received signal strengths from the two or more antennas;
- and
- generating, by the apparatus, a signal indicating a direction of the radio transmission based on comparing the received signal strengths.
A non-transitory tangible computer-readable medium for indicating a direction of a radio transmission, the computer-readable medium comprising executable instructions for:
- receiving a radio transmission by at least one vector detection device, wherein the at least one vector detection device comprises two or more antennas, an attenuating material between at least one of the antennas and a source of the radio transmission, and a shielding material configured so that the radio transmission goes through the attenuating material or is shielded by the shielding material, and wherein the attenuating material is arranged to reduce the signal strength of the radio transmission corresponding to an angle of the source with respect to at least one of the antennas;
- comparing received signal strengths from the two or more antennas;
- and
- generating a signal indicating a direction of the radio transmission based on comparing the received signal strengths.
