Abstract :
A new and simple design for thin and broadband circuit analogue absorbers is presented. The proposed absorber is composed of a two-dimensional periodic array of multiple patches printed on a conductor-backed substrate, which exhibits the property of multiple resonances and provides a wide absorbing bandwidth. Measured results show that this simple absorber has a bandwidth of 76% for 10 dB RCS reduction and its thickness is only one-eighth free-space wavelength at the centre frequency
