Title:
CIRCULARLY POLARIZED WAVE PLANE ARRAY ANTENNA
Document Type and Number:
Japanese Patent JPS62220004
Kind Code:
A
Abstract:

PURPOSE: To improve the circularly polarized wave axial ratio with simple constitution by synthesizing the phase with a couple of 1/4 wavelength lines and applying a printed resistor between a couple of the 1/4 wavelength lines.

CONSTITUTION: A part where a conductor foil 7 as a suspended line is connected to a synthesis section 11 is formed by a couple of the 1/4 wavelength lines 40, 41 and the printed resistor 42 is applied between the lines 40 and 41. In supplying power from a terminal C, a 1/4 power passes through the printed resistor 42 and the 3/4 power passes through the line 40, and the 2/4 power in the 3/4 through the line 40 is fed to a terminal A and the 1/4 power passes through the line 41. The 1/4 power through the line 41 an the 1/4 power through the printed resistor 42 are synthesized in the opposite phase but the same amplitude, then they are cancelled with each other substantially and no power is sent to a terminal B finally.
