Abstract
A device for testing a transmitter and/or receiver of electromagnetic waves includes a hollow metal body, dimensioned to function as a waveguide, including a hole for receiving a test antenna and a hole for receiving the receiver to be tested, a test antenna inserted into the hole, and a signal generating device connected to the test antenna. A method of testing the transmitting and/or receiving function of an antenna includes the steps of inserting the antenna and a test antenna into holes in the appropriate side of a waveguide, transmitting a signal from the antenna or the test antenna, and registering the signal strength received by the antenna or the test antenna that did not transmit the signal.
Claims12
An apparatus for testing a receiver of electromagnetic waves, said apparatus comprising:
- a hollow metal body dimensioned to function as a waveguide for said electromagnetic waves, said metal body being enclosed on all sides and having a first hole for receiving a test antenna and a second hole for receiving a portion of a device to be tested,
- a test antenna inserted into said first hole, and
- a signal generating device connected to said test antenna.
An apparatus for testing a transmitter of electromagnetic waves, said apparatus comprising:
- a hollow metal body dimensioned to function as a waveguide for said electromagnetic waves, said metal body being enclosed on all sides and having a first hole for receiving a test antenna and a second hole for receiving a portion of a device to be tested,
- a test antenna inserted into said first hole, and
- a signal measuring device connected to said test antenna.
An apparatus for testing a device for receiving and transmitting electromagnetic waves comprising:
- a first hollow metal body dimensioned to function as a waveguide for electromagnetic waves in a first frequency range, said first hollow metal body having a first hole for receiving a first test antenna,
- a second hollow metal body dimensioned to function as a waveguide for electromagnetic waves in a second frequency range, said second hollow metal body having a second hole for receiving a second test antenna,
- a section connecting said first and second hollow metal bodies, said section having a third hole for receiving the device to be tested, wherein the first hollow metal body, the second hollow metal body, and the section connecting the first and second hollow metal bodies form a substantially enclosed structure, and
- at least one of a signal generating device and a signal measuring device, each connected to said test antenna.
A method of testing a transmitting function of an antenna comprising the steps of:
- inserting an antenna into a first hole in a side of a waveguide, said waveguide being a substantially enclosed structure,
- inserting a test antenna into one of the same and an opposite side of the waveguide,
- transmitting a signal having a corresponding signal strength from the antenna, and
- registering the signal strength received by the test antenna.
A method of testing a receiving function of an antenna comprising the steps of:
- inserting an antenna into a first hole in a side of a waveguide, said waveguide being a substantially enclosed structure,
- inserting a test antenna into a second hole in one of the same and an opposite side of the waveguide,
- transmitting a signal having a corresponding signal strength from the test antenna, and
- registering the signal strength received by the antenna.
