<p>A collinear antenna (100) is formed as a planar circuit on a dielectric substrate (102). The antenna comprises a central planar conductive transmission line (108) disposed along a central axis for conducting radio frequency (RF) signals to or from the antenna. A planar conductive ground element (110) is formed about the central axis. A collinear array of planar conductive transmission line segments (112) is disposed in opposed pairs adjacent to the ground element about the central axis. Each transmission line segment is conductively coupled to corresponding outer radiating dipole elements (114), and arranged longitudinally adjacent to at least one other such segment. As a result, RF signals are electromagnetically coupled between adjacent segments. A feed point (116) comprises at least one slot formed in the ground element, whereby RF signals are electromagnetically coupled between the central transmission line and a transversely adjacent one of the transmission line segments. 122 120 118 112 114 110 Figure 1 KL~7j27~104 Figure 2 7T Figure 3</p> |
