First Claim
1. An antenna arrangement comprising:
- a pair of at least generally planar opposing antenna arms, each of which supports a first high frequency antenna current that is produced responsive to an input and each of which includes a peripheral outline for confining the first high frequency current to a pair of first and second dominant paths, that are defined by the peripheral outline, in a spaced apart relationship across each of the opposing antenna arms so as to define an area therebetween which is isolated, at least to an approximation, from the first and second dominant paths; and
a configuration located in said area between the first and second dominant paths of at least one of the antenna arms for producing an additional high frequency current responsive to the input which additional high frequency current cooperates with the first high frequency antenna current to produce an overall antenna response, wherein said configuration includes a grating in said area that is isolated from the dominant paths for producing the additional high frequency current.

Abstract
An antenna arrangement is described in which a pair of at least generally planar opposing antenna arms each support a first high frequency antenna current responsive to an input. Each arm includes a peripheral outline for confining the first high frequency current to a pair of first and second dominant paths, that are defined by the peripheral outline, in a spaced apart relationship across each of the opposing antenna arms so as to define an isolated area between the first and second paths. A configuration is located in this area of at least one of the antenna arms for producing an additional high frequency current responsive to the input. The additional high frequency current cooperates with the first high frequency antenna current to produce an overall antenna response. In one feature, the opposing antenna arms are bow arms which cooperate to define an overall bow-tie configuration as the peripheral outline.
