DUAL-BAND ANTENNA ARRAY AND RF FRONT-END FOR AUTOMOTIVE RADARS
First Claim
1. An automotive radar comprising:
- a printed circuit board having a top surface and a bottom surface;
a processor mounted on the bottom surface of the printed circuit board, the processor configured to generate a first frequency signal and a second frequency signal;
a second liquid crystal polymer layer formed on the top surface of the printed circuit board;
a second microstrip array printed on the second liquid crystal polymer layer, the second microstrip array having a patch;
a first liquid crystal polymer layer formed on the second liquid crystal polymer layer;
a first microstrip array printed on the first liquid crystal polymer layer, the first microstrip array having a perforated patch; and
a transmit/receive module connected to a bottom surface of the second liquid crystal polymer layer, connected to the processor, and configured to transmit the first frequency signal to the first microstrip array and the second frequency signal to the second microstrip array.
