In-line CP patch radiator
First Claim
1. An antenna element, comprising;
- a microstrip transmission line having a series of conductive patch radiating elements, each one of the radiating elements having a pair of conductive patches, each one of the patches being disposed on opposite edges of the transmission line, each of the patches having a rhomboidal shape with edges disposed at an oblique angle with respect to the microstrip transmission line and displaced from each other by a multiple of about half of a nominal operating wavelength of the antenna element, the edges of one of the patches being substantially ninety degrees to the edges of the other one of the patches, the patches in each pair being staggered with respect to each other along the transmission line by substantially a quarter wavelength at the nominal operating wavelength of the antenna element.

Abstract
An antenna element is disclosed with a microstrip transmission line having a series of conductive patch radiating elements, each one of the radiating elements having a pair of conductive patches, each one of the patches being disposed on opposite edges of the transmission line, each of the patches having a rhomboidal shape with edges disposed at an oblique angle with respect to the microstrip transmission line, the edges of one of the patches being at substantially ninety degrees to the edges of the other one of the patches, the patches being staggered with respect to each other along the transmission line by substantially a quarter-wave length at the nominal operating wavelength of the antenna element.

7. An antenna comprising;
-
a transmission line comprising; a ground plane conductor; a dielectric; a strip conductor, such strip conductor being separated from the ground plane by the dielectric; a plurality of first rhomboidal conductive patches disposed serially along, and integrally formed with, a first side of the strip conductor, first edges of the first patches intersecting the strip conductor at a first oblique angle and a second edge of the first patches connecting the first edges substantially parallel to the transmission line, each first patch being integral with the strip conductor a distance of a multiple of about half of a nominal operating wavelength of the antenna; and a plurality of second rhomboidal conductive patches disposed serially along, and integrally formed with, a second side, opposite the first side, of the strip conductor, first edges of the plurality of second patches intersecting the strip conductor at a second oblique angle substantially ninety degrees relative to the first oblique angle and second edges of the second patches connecting the first edges of the second patches substantially parallel to the transmission line, each second patch being integral with the strip conductor a distance of a multiple of about half of a nominal operating wavelength of the antenna; wherein each one of the first patches is staggered about a quarter wavelength at the nominal operating wavelength of the antenna from a corresponding one of the second patches. - View Dependent Claims (8, 9, 10, 11)

12. An antenna comprising:
-
a conductive ground plane; a dielectric disposed over the ground plane; an elongated conductor displaced a distance from the ground plane by the dielectric; and a plurality of radiating conductors each including first and second edges extending from the elongated conductor at oblique angles and displaced from each other such that energy applied to the plurality of radiating conductors will radiate primarily from the first and second edges thereof; wherein pairs of the plurality of radiating conductors are disposed on opposite sides of the elongated conductor and are displaced along the elongated conductor relative to each other by approximately a quarter of a nominal operating wavelength of the antenna. - View Dependent Claims (13, 14)
