A broad band monopole antenna may include a planar electrically conductive base surface arranged horizontally, a planar polygonal shaped antenna element arranged vertically spaced above the base surface by a distance (D), and a planar polygonal shaped ground plane arranged vertically between the base surface and said antenna element. The ground plane may be electrically connected to the base surface.

Broad band monopole antenna

A broad band dipole antenna includes a first top radiator which is a planar polygonal shaped surface arranged parallel to vertical axis of the broad band dipole antenna, a first bottom radiator which is a planar polygonal shaped surface arranged parallel to the first radiator and below of the first top radiator, a first coupler which is a planar polygonal shaped surface arranged in close proximity to both the first top radiator and the first bottom radiator, N&#x2212;1 top radiators where each next top radiator is a copy of the previous top radiator which is rotated by approximately 360&#xb0;/N around the vertical axis, where N is an integer greater than one, N&#x2212;1 bottom radiators where each next bottom radiator is a copy of the previous bottom radiator which is rotated by approximately 360'/N around the vertical axis, N&#x2212;1 couplers where each next coupler is a copy of the previous coupler which is rotated by approximately 360&#x2032;/N around the vertical axis, a first jumper which connects bottom sides of all the top radiators, and a second jumper which connects top sides of all the bottom radiators.

Broad band dipole antenna

A compact dual-band air core helix antenna may include two sets of quadrifilar helix antenna elements with each of the antenna elements having different arm lengths. The helix antenna may be configured such that the antenna elements are printed on a foldable printed circuit board. Radiating elements of the antenna elements may be fed with four inputs and each of the four inputs may have a same amplitude and quadrature phase difference (e.g., 0, 90, 180, 270 degree phase shifts).

Dual-band shaped-pattern quadrifilar helix antenna

The present invention is a single or multiple non-resonant slot antenna where said slots are formed from a continuous upward extension of the conducting ground plane with lateral horizontal planar extensions to form a top plane defining said slots.

Ground surrounded non-resonant slot-like patch antenna

The present invention antenna preserves the general size and form factor of the prior art loop antennas while providing the benefits of multiple point feeds at less than one wavelength in separation of feed points. The invention antenna obtains omnidirectional radiation and improved efficiency over the prior art by way of dual slotted, open ended cylindrical or rectangular box structures fed with high impedance feed lines.

Omni directional space-fed antenna with loop patterns

The present invention is a dual frequency and circularly polarized microstrip antenna with a ground plane, a mid layer above the ground plane with a parasitically driven resonant mid patch (for transmissions at a second frequency), a top layer with a directly driven patch parasitically driving the mid patch (for transmissions at a first frequency), and parasitic elements.
