Abstract

PURPOSE:To omit jumpers and to avoid conversion loss, by changing a power division circuit into a rat race circuit and using a branch line coupler. CONSTITUTION:The length from microstrip antennas 2a, 2b to a branch line coupler is different by 1/4 wavelength and the length from microstrip antennas 2c, 2d to the branch line coupler is also different by 1/4 wavelength. Thus, the sum and difference signals of the input signal are obtained at the remaining terminals of branch line couplers 4a, 4b. The power supply to the branch line coupler is made with rat race circuits 4c, 4d. Signals relating to sum, height and azimuth angle can be obtained from four apertures 2a-2d at external connecting terminals A, B, C.
