Abstract
Background: It gives out the design and verification of single-layer dual-band antenna
unit and multi-layer dual-band broadband antenna unit of phased array antenna, and verifies that
the multi-layer dual-band broadband antenna unit can meet the design requirements of the receiving
frequency band.
Objective: It gives out the design and implementation of a wide-band circularly polarized conformal
antenna, and presents the characteristics analysis of the antenna.
Methods: Through related simulation methods, the proposed methods are verified and they can
effectively solve the array phase compensation and beam shaping and control in the wide-band
circularly polarized conformal antenna.
Results: Based on the basic design of the antenna, the active superposition algorithm, phase compensation
technology and particle swarm optimization antenna beam shaping technology are both studied.
Conclusion: The proposed wide-band circularly polarized conformal antenna can be used in the
actual application.
Keywords:
Broadband, circularly polarized, conformal antenna, design, implementation, simulation methods, frequency band.
