Patent ID: 11870162
Assignee: THE BOEING COMPANY
Field: Telecommunications (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. An antenna system, comprising:
a first microstrip comprising,
an array of conductors,
a plurality of loads, wherein each of the loads connects one of the conductors to an adjacent one of the conductors;
a conductive backplane, and
a dielectric disposed between the conductors and the conductive backplane,
wherein the array is coupled to a feed line and is configured to:
emit electromagnetic radiation in response to an input signal being input to the array through the feed line; or
output an output signal to the feed line in response to electromagnetic radiation being received on the array; and

a second microstrip comprising a director disposed in front of the array, wherein,
the director has a first reactive load having a first complex impedance that is tailored to increase a directivity of the antenna system by reactively loading the conductors,
the first reactive load comprises a plurality of conductive components separated by one or more dielectric layers; and
the plurality of conductive components comprise at least one of a capacitive pad or a wire having an inductance.
