Patent ID: 8717246

Claim:
A stacked antenna comprising: a first dielectric substrate; a second dielectric substrate stacked on the first dielectric substrate; at least one vertical conductive structure penetrating the first dielectric substrate or the second dielectric substrate; at least one transmission line structure disposed between the first and second dielectric substrates; a driven element disposed between the first and second dielectric substrates and electrically connected to the conductive structure through the transmission line structure for radiating a radio wave; at least one reflector spaced from the driven element by the first dielectric substrate and disposed under the first dielectric substrate for reflecting the radio is wave to adjust an antenna radiation pattern; a director spaced from the driven element by the second dielectric substrate for enhancing a directivity of the radio wave a third dielectric substrate, wherein the first dielectric substrate is stacked on the third dielectric substrate, and the first dielectric substrate is disposed between the second and the third dielectric substrate; and a ground element spaced from the reflector by the third dielectric substrate and disposed under the third dielectric substrate, whereby the driven element is isolated from noise interference, wherein the conductive structure penetrates the second dielectric substrate or penetrates the first and third dielectric substrates.
