This paper presents a slot antenna array with reconfigurable radar cross section (RCS). The system is formed by combining liquid absorber 2*2 array. consists of polymethyl methacrylate (PMMA) container, 45% ethanol layer, and metal ground,which attached to the surface incident wave can be absorbed rather than reflected in other directions when PMMA container filled ethanol, which reduces monost...

This paper focuses on the development of a novel single layer dual band proximity fed gap coupled microstrip array antenna. A basic 2x1 microstrip patch array consisting of a pair of rectangular patches which are coupled with a centrally placed microstrip line in the same plane and an arrow headed dumbbell shaped slot in the ground plane is investigated. By using two additional parasitic patche...
