Abstract :
A fixed beam linearly polarized array for automotive satellite reception suitable for large scan angles has been demonstrated. Using the fixed beam subarray is the key to reduce the number of phase shifters at the cost of quantization errors and increased grating lobes. The azimuth beam steering is achieved mechanically utilizing an electronically controlled motor. The fixed beam array was successfully tested to receive actual satellite TV signals at locations where satellite view angle was close to 32deg.
