Summary:
A DCP-RLSA filled with lightweight honeycomb structures is designed and fabricated. Calculated antenna characteristics satisfy the desired specifications. In the measurement, in the both polarizations, the frequency dependences of the directivities satisfy the specification of over 20 dBi in the fractional bandwidth of 5 % though the center frequency shifts to lower by around 3 % and 1 %, respectively. The measured XPDs of the both polarizations are around 20 dB and still lower than the specification.
