CPC H01Q 7/08 (2013.01) [H01F 1/348 (2013.01); H01F 10/24 (2013.01); H01Q 1/38 (2013.01)] | 20 Claims |
1. 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.
