Fabrication and testing of pyramidal X-band standard horn antenna

الملخص EN

Standard horn antennas are an important device to evaluate many types of antennas, since they are used as a reference to any type of antennas within the microwave frequency bands.

In this project the fabrication process and tests of standard horn antenna operating at X-band frequencies have been proposed.

The fabricated antenna passed through multi stages of processing of its parts until assembling the final product.

These stages are (milling, bending, fitting and welding).

The assembled antenna subjected to two types of tests to evaluate its performance.

The first one is the test by two port network analyzer to point out S & Z parameters, input resistance, and the voltage standing wave ratio of the horn, while the second test was done using un-echoic chamber to measure the gain, side lobes level and the half power beam width.

The results of testing come nearly as a theoretical value of the most important of antenna parameters, like; gain, side lobe level, -3 dB beam width, return loss and voltage standing wave ratio "VSWR", input Impedance.
