Aperture Coupled High Gain Patch Antenna of Double Resonance type with Feeding Microstripline according to Dielectric Thickness Change

摘要

PURPOSE: A dual resonance type aperture-coupled high-gain patch antenna is provided to form a dual resonance band on a feeder by using an impedance variation of the feeder according to a thickness variation of a dielectric. CONSTITUTION: A dual resonance type aperture-coupled high-gain patch antenna includes a director(1) for radiating electric waves of predetermined frequencies and a feeder(3). The dual resonance type aperture-coupled high-gain patch antenna further includes a window(8), a dielectric(6), and a supporter(5). The window(8) includes a taper slot(2) to remove unnecessary electric waves. The dielectric(6) has different thickness according to each part. The feeder(3) has a bending part(7) according to a thickness variation of the dielectric. The supporter(5) is used for maintaining intervals among the director(1), the window(8), the dielectric(6), and a reflector(4).
