Two-tier wide band antenna
First Claim
1. An antenna comprising a first radiating structure located substantially in a first plane and having a feed point located substantially at a first end of said radiating structure;
- a second radiating structure located substantially in a second plane, said first plane being spaced apart from and substantially parallel with said second plane; and
a block of dielectric material located substantially between said first and second radiating structures to provide a spacing between said first and second planes, wherein said second radiating structure comprises at least two spaced-apart, elongate radiating elements, each of said at least two radiating elements having a respective first end that is electrically connected to said first radiating structure substantially at a second end of said first radiating structure, said respective first end of said at least two radiating elements being substantially in register with said second end of said first radiating structure.

Abstract
A two-tier wideband antenna comprising a chip of a dielectric material with an upper radiating structure and a lower radiating structure, the dielectric chip being mounted on an insulating carrier substrate which includes a feed-line to connect the antenna to a transceiver device. The lower radiating structure comprises two side elements which have a large aspect ratio so as to reduce the frequency of the lower band edge of the frequency response of the antenna when compared with the frequency response of a monopole patch antenna fabricated on a similar dielectric chip. The antenna of the present invention is suitable for operation over an ultra wideband, e.g. a frequency range extending from 3.1 to 10.6 GHz
