In this paper a dual mode helix is being proposed whereby the combined antenna acts as a single structure comprising of two quadrifilar helix antennas running in parallel and connected at top radial sections and sideways helical sections through pin diodes switches in such a way that space and land mode can be selected by the application of appropriate dc… CONTINUE READING
