Abstract: A method of radar detection and a radar system for a motor vehicle are described. The radar system includes a transmitter for transmitting a radar signal having a time period, a plurality of receivers for receiving the transmitted radar signal reflected by an object, a signal compressor having a plurality inputs coupled to each of the receivers and at least one signal compressor output, the signal compressor being configured to compress the received signals to fewer output signals, each output signal having a number of samples. A signal re-constructor having at least one input coupled to each the signal compressor output and configured to determine a plurality signal strength values from the compressed signals, each signal strength value corresponding to a signal strength for a respective time-of-flight and angle-of-arrival value pair of a received signal. The radar system may detect an object with less memory and a lower power consumption while maintaining angular resolution.

Abstract: Antenna switches (1,10) in dual-band or multi-band mobile phones are according to a basic idea provided with a serial semiconductor switches (11,21,12,22) per transmitting branch (2,3) and with a further semiconductor switch (13,23) coupled in parallel to a receiving branch (4,5,6), to obtain isolation between branches (2-6) in a simple way. Said semiconductor switches are PIN diodes or MEMS switches or pHEMT switches. Another semiconductor switch (14) coupled in parallel to the receiving branches (4-6) allows together with said further semiconductor (13) the introduction of elements (15,16) without a transmission line. Alternatively, the antenna switch (1,10) may comprise a transmission line (24,25), in which case the receiving branches (4,5,6) can be switched via transistor switches (26,27,28). This all improves isolation, reduces costs, complexity, size and high Radio-Frequency (RF) losses.

The shield (21) is located between the antenna (31) and the semiconductor device (11), and is present on the same side (2) of the substrate (1) as the semiconductor device (11) and the antenna (31). By preference, the antenna (31) and the shield (21) are connected to one another by support means (32, 42).

The antenna (2) of the antenna device (10) can be tuned by means of matching bridges (34, 37), each of which comprise a reactive component (3,4) and a switch (25, 26). Preferably, the switches (25,26) are located outside the antenna device (10) such that a standardized antenna device (10) can be used.
