Systems, devices and methods for flexible meander line patch antenna
The disclosed antenna is designed to work at GPS L1, GPS L2, GPS L5/GLONASS/BEIDOU frequencies. The antenna is fabricated on a flexible body and includes a meander line between a 50Ω RF feeding cable on the ground plane and a patch element. The resonant mechanism is excited by the meander line structure from 1170 Mhz to 1610 MHz and the Patch gives the wideband performance. Most configurations of the antenna have a low profile of about 0.15 mm.
1. An antenna comprising:
a planar patch element located within a rectangular boundary, the planar patch element positioned substantially within three contiguous quadrants of the rectangular boundary;
an open-ended planar meander line positioned within a fourth quadrant of the rectangular boundary and surrounded on at least two sides by the planar patch element, the open-ended planar meander line continuous with the planar patch element at one end of the planar meander line; and
a planar ground plane positioned adjacent the planar patch element.
2. The antenna of claim 1 , wherein the quadrants of the rectangular boundary are substantially rectangular in shape.
3. The antenna of claim 1 , wherein the fourth quadrant of the rectangular boundary comprises outside edges defined by portions of two adjacent sides of the rectangular boundary.
