Abstract: PURPOSE: A high efficient broadband micro-strip patch alignment antenna is provided to improve an electromagnetic coupling characteristic between a radiative patch and a feeder of a micro-strip patch antenna for linearly polarized wave or circular polarized wave. CONSTITUTION: A ground conductor layer(7) is formed on an entire surface of a dielectric layer(6). A feeder(5) and the first patch(8) are formed on an upper face of the dielectric layer(6). The feeder(5) is electrically connected to the first patch(8). The first foam layer(4) is formed on the feeder(5) and the first patch(8). A dielectric film(3) is formed on the first foam layer(4). The second patch(1) is formed on the dielectric film(3). The second foam layer(2) is formed on the second patch(1). The first and the second patches(8,1) are overlapped each other. The first patch(8) is electromagnetically connected to the second patch(1). The first and the second foam layers(4,2) have a plurality of air bubbles and low dielectric constants, respectively.

Abstract: PURPOSE: A satellite tracking controller system and a control method of mobile tracking antenna for low cost multi-satellite reception are provided to form a low-priced tracking antenna of high performance under multiple satellite signal circumference. CONSTITUTION: A dual-polarization multiple satellite mobile tracking antenna(1) receives a satellite signal of a desired polarized wave according to a polarized wave control signal of a tracking beam generator(2). The tracking beam generator(2) converts the satellite signal of the dual-polarization multiple satellite mobile tracking antenna(1) to a satellite tracking signal for determining an elevation and an azimuth and provides the polarized wave control signal to the dual-polarization multiple satellite mobile tracking antenna(1). A tracking signal detector(3) receives the satellite tracking signal from the tracking beam generator(2) and a tracking frequency selection signal from a satellite tracking controller(4). An elevation control motor(5) and an azimuth control motor(6) moves a direction of the beam of the dual-polarization multiple satellite mobile tracking antenna(1) in order to track the desired satellite signal.
