This paper presents an investigation of the reflectivity performance for hollow pyramidal shape microwave absorbers. The pyramidal absorbers used in this study is constructed using four 15cm-pyramidal absorbers stacked on each other to equal the height of one single 45cm-absorber. The wave frequency ranging from 8GHz to 12 GHz was chosen for simulation and measurement of the absorber performance. The reflectivity performances of the stacked pyramidal absorbers were compared to single level pyramidal absorbers in term of their reflectivity performances. The result shows that the stacked pyramidal absorber has higher absorption level an average absorption of -24 dB for the above frequency range.
