Title:
WAVEGUIDE ANTENNA
Document Type and Number:
Japanese Patent JP3859520
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a waveguide antenna with downsizing and weight reduction.
SOLUTION: A dielectric material 3 incorporating a low frequency feeding strip line 6 for feeding a low frequency waveguide antenna 1 is mounted on the low frequency waveguide antenna 1. A conductor plate 5 for electromagnetic wave isolation is placed on the dielectric material 3, and a dielectric material 4 incorporating a high frequency feeding strip line 7 for feeding a high frequency waveguide antenna 2 is mounted on the high frequency waveguide antenna 2. The low frequency waveguide antenna 1, the low frequency feeding strip line 6, the high frequency waveguide antenna 2, and the high frequency feeding strip line 7 are respectively connected via coupling holes.
