Smart antenna
First Claim
1. An antenna assembly including a driving monopole element and an array of parasitic monopole elements arranged in an annular array around the driving monopole element, wherein the parasitic monopole elements are of bent or curved configuration;
- wherein the driving monopole element has a height of substantially ⅛
th or less than an ⅛
th of the tuned wavelength and the parasitic elements a length of substantially ¼
of the tuned wavelength but bent or curved so as to have a maximum height equivalent to that of the driving monopole element.

Abstract
A smart antenna assembly includes a driving monopole element and an array of parasitic monopole elements arranged in an annular array around the driving monopole element, wherein the parasitic monopole elements are of bent or curved configuration, bending or curving towards the driving monopole element. Preferably, each parasitic monopole element has a portion thereof which is parallel or substantially parallel to the driving monopole element. The assembly provides a compact steerable antenna assembly.
