Abstract
A loop antenna which is electrically small relative to a wavelength of a signal which it is designed to receive. The antenna is an electrically small, low profile, band switchable antenna which can be mounted on a metallic surface such as a truck or railway car rooftop and can be used to communicate with earth satellites. The antenna is polarized such that the plane containing the electric field is horizontal. Alternatively, the antenna can receive circularly polarized signals.
