There is disclosed a meanderline loaded antenna comprising a ground plane, a non-driven vertical element affixed thereto, a driven vertical element and a shaped top radiating element conductively connected between the driven and non-driven vertical elements. One or more segments or regions of the top plate are resonant depending on the input signal frequency. Since top plate presents several such segments or portions, several different resonant frequencies (a band of closely spaced resonant frequencies or multiple bands of disparate resonant frequencies) are presented to the antenna driving signal, thus allowing the antenna to resonate at several different frequencies and bands. In another embodiment, the antenna comprises a plurality of top radiating elements in parallel spaced relation or in a single plane, wherein each top radiating element is resonant at a different frequency, when considered with the effective lengths of the other antenna elements. Thus the plurality of top radiating plates accommodate multiple resonant frequencies and wideband operation. A plurality of such antennae can be used as elements to form an antenna array.

There is disclosed a meanderline loaded antenna comprising a ground plane, a plurality of vertical elements orthogonally affixed thereto, a driven vertical element affixed thereto and a horizontal element between the vertical elements. All but one of the plurality of vertical elements have an effective electrical length that is a quarter wavelength of the antenna operating frequency. Thus, these vertical elements represent an open and do not effect the antenna performance characteristics. One of the plurality of vertical elements will be operative and therefore the antenna length comprises the length of the operative element, the length of the driven element, and the length of the top plate therebetween.

There is disclosed a meanderline loaded antenna comprising a ground plane, two vertical elements orthogonally affixed thereto, and a horizontal element between the two vertical elements. A meanderline coupler interconnects the horizontal element, at each of its ends, to the vertical elements. The antenna further includes an additional radiating element extending from the horizontal element in approximately planer relationship therewith. Additionally, the antenna includes a tuning element extending from the horizontal element and forming an acute angle with the adjacent vertical element.

There is disclosed an antenna exhibiting resonance over a broad frequency band or over a plurality of closely-spaced frequency bands, comprising a ground plane, a non-driven element affixed substantially perpendicular to the ground plane, a driven element affixed substantially perpendicular to the ground plane and a horizontal conductor electrically connected between the driven and the non-driven elements and disposed substantially parallel to the ground plane. The non-driven and the driven elements further comprise periodic slow wave structures. The periodic slow wave structures are configured to provide a substantially constant propagation factor with respect to the applied signal frequency, such that the antenna exhibits broad resonance characteristics.

An antenna incorporating slow wave structures. The antenna comprises at least two conductive serpentine structures disposed on a dielectric substrate and further comprising an oppositely disposed conductive top plate electrically connected to the conductive serpentine structures and farther electromagnetically connected thereto. In one embodiment the antenna further comprises a ground plane below the dielectric substrate.
