Abstract :
The expression of the field radiated by a rhombic antenna, taking into consideration both the vertical and the horizontal polarization components, is used to establish the theory of the array of two stacked rhombics and of the array of four rhombics in a stacked and interlaced arrangement. The main conclusions obtained are that for convenient values of the vertical and horizontal spacings between the antennas of the array, there is a greater concentration of power radiated along the directions of the main lobe of the pattern and, as a result, these arrays show an appreciable gain over a conventional rhombic. Practical rules for the design of these arrays for point-to-point and broadcasting are given in some detail.
