Abstract
Two or more high permeability magnetodielectric slabs in combination with electrical coils wound on each slab form a compact antenna that radiates electromagnetic signals efficiently in the omnidirectional pattern.
Claims20
A compact and efficient antenna, comprising:
- a first magnetodielectric material slab having an x, y, z dimension with the z dimension being smaller than the x, y dimensions;
- a second magnetodielectric material slab having an x, y, z dimension with the z dimension being smaller than the x, y dimensions, wherein the second magnetodielectric material slab is placed in parallel to the first magnetodielectric material slab with a gap;
- a first conductive wire looping at least half a first coil turn around the first magnetodielectric material slab forming a first coil, having a first end and second end;
- and
- a second conductive wire looping at least half a second coil turn around the second magnetodielectric material slab, forming a second coil, having a third end and a fourth end,
- wherein the first coil and the second coil are connected to an AC source or a feed network producing an omnidirectional radiation in the azimuth plane with a gain equal to or greater than 3 dBi compared to a marine monopole antenna.

A compact and efficient antenna, comprising:
- at least two or more magnetodielectric material slabs being stacked together with a gap;
- a first plurality conductive wires looping, at least, one first coil turn around the first magnetodielectric material slab, forming a first plurality of coils;
- and
- a second plurality conductive wires looping, at least, one second coil turn around the second magnetodielectric material slab, forming a second plurality of coils,
- wherein a power divider is used to split the source signal to feed the multiple coils wound around the slabs, producing an omnidirectional radiation in the azimuth plane with a gain equal to or greater than 3 dBi compared to a marine monopole antenna.
