A Substrate Integrated Waveguide (SIW) planar array is
presented using a right handed circularly polarized (RHCP) element
with four crossed tilted radiating slots. In addition, a pair of metallic
tuning vias is included to really improve the reflection of longest
slots. A corporate feeding network over SIW has been designed for
distributing the input signal to 128 radiating elements, divided into 8
progressive wave linear arrays of 16 elements each. The designed planar
array has been manufactured and measured to verify the antenna
performance. 25.5 dB gain, 2.33 dB axial ratio, as well as 85% radiation
efficiency values have been experimentally achieved at 17 GHz. A 3%
usable bandwidth (16.75{17.25 GHz) is obtained due to the typical
frequency main beam tilt dispersion in the elevation plane of the
progressive wave arrays.
