Abstract:
An antenna comprising:a conductive plate; a first conductive element having a first edge; a second conductive element having a first edge electrically connected to said conductive plate said second conductive element further including a second edge opposingly spaced apart from the first edge of said second conductive element; a shaped conductive element having a plurality of independently excitable regions, wherein current flow through one or more of said regions determines the effective length of the antenna, and wherein a first location of said shaped conductive element spaced proximate to the first edge of said first conductive element so as to create a gap there between, and wherein a second location of said shaped conductive element is spaced proximate to the second edge of said second conductive element so as to create a gap there between; a first meanderline coupler electrically connected between said first conductive element and said shaped conductive element so as to provide a path across the gap there between; second meanderline coupler electrically connected between said second conductive element and said shaped conductive element so as to provide a conductive path across the gap there between; and wherein said first and said second meanderline couplers have a selectable electrical length.
