Abstract :
This paper presents an anti-jam GPS array. The antenna is comprised of 4 small size radiating cavities filled with two stacked patches and a series of dielectric substrates and a foam layer. The main features of the antenna are low profile shape and low inter-element coupling. The antenna design is compatible with high impedance surface (HIS) insertion, which can potentially improve the anti-jam capabilities of the array by providing further inter-element coupling reduction.
