Title:
FREQUENCY STEERED PHASED ARRAY ANTENNA
Document Type and Number:
WIPO Patent Application WO/2023/153724
Kind Code:
A1
Abstract:
The present invention relates to a frequency steered phased array antenna which adjusts beam radiation angle according to frequency for broadband electromagnetic waves, and radiates beams of uniform intensity over a broad range of angles including directly forward. The frequency steered phased array antenna according to the present invention comprises: a directional coupler including a serial feed line that is stacked in n layers and has a plurality of coupling holes formed in one direction in each of the layers; and a radiating module including n horn antennas respectively connected in correspondence to the n layers of the serial feed line, wherein the plurality of coupling holes are formed in each of the layers of the serial feed line at intervals of 1/4 of the wavelength (λ) of electromagnetic waves (radio waves) supplied to the serial feed line, and the horn antennas radiate the electromagnetic waves output through the coupling holes of the serial feed line.
