摘要： Disclosed herein is the structure of a Square Quadrifilar Helical antenna (S-QHA). The structure of the S-QHA includes a square column, four radiation elements, and a feed network. The four radiation elements are formed on the square column. The feed network is disposed at the top or bottom of the square column, and feeds signals to the radiation elements at a phase difference of 90 degrees in a clockwise or counterclockwise direction. As a result, the S-QHA according to the present invention can receive circularly polarized signals.

摘要： The present invention relates to a lowpass filter for effectively suppress a spurious in stop-band. The lowpass filter includes an input port microstrip element; an output port microstrip element; a first open-ended microstrip element; a second open-ended microstrip element; a first connector microstrip element; and, a second connector microstrip element. The each open-ended microstrips of the present invention is composed of distributed elements and distributed resistances connected each others in series and operated as a capacity, has a large impedance of the microstrip by low influence of a resistance in case of a low frequency, and has a small impedance of the microstrip by high influence of a resistance value in case of a high frequency. The present invention can effectively suppress the spurious characteristic, which is a disadvantage of the conventional lowpass filter composed of transmission lines at the RF band or the microwave band, by inserting resistance elements in open-ended microstrips.
