23. A method of tuning a dual frequency cavity backed
slot antenna comprising the steps of:
(a) providing a substrate with a surface, said surface
including thereon:
(i) a continuous slot;
(ii) first electrically conductive metallization
disposed internal of said slot and extending to said slot;
(iii) second electrically conductive metallization
disposed external to said slot and extending to said slot,
said first and second electrically conductive metallization
defining said slot; and
(iv) at least one pair of axially aligned
frequency adjusting means, aid pair comprising one of an
indentation or a tab in each of said first and second
electrically conductive metallization; and
