چکیده
Silicon W-band automotive radars have been an active areas of research and development in the past 12 years, and are in wide use by the automotive industry for collision avoidance and cruise control [1-4]. Recently, several silicon chips have been developed for automotive radars with scanning (or switch-beam capabilities), and the scanning systems are based on digital or RF beamforming techniques [4, 5]. In particular, a 16-element phased array receiver chip with build-in-self-test capabilities was presented in [6] with state of the art performance in phase and amplitude control. This work expands on [6] by integrating the chip in a low-cost package and demonstrating a W-band automotive radar with wide-angle scanning capabilities.

Phased array antenna using MEMS phase shifter
This article presents a phased array antenna employing MEMS phase shifter. The proposed phased array antenna consists of eight square patch antennas operating at 10.4 GHz with a bandwidth of 400 MHz. Feed line for each patch passes through a MEMS phase shifter realized by a series of bridges above the transmission line. The distance between the bridge and the transmission line underneath it is ...

In this paper, we propose a multi-beam and multi-range (MBMR) radar with frequency modulated continuous wave (FMCW) waveform and digital beam forming (DBF) algorithm to cover a detection area of long range and narrow angle (150 m, ±10◦) as well as short range and wide angle (60 m, ±30◦) as a single 24 GHz sensor. The developed radar is highly integrated with multiple phased-array antennas, a tw...
متن کاملPerformance of Target Detection in Phased-MIMO Radars
In this paper, the problem of target detection in phased-MIMO radars is considered and target detection performance of phased-MIMO radars is compared with MIMO and phased-array radars. Phased-MIMO radars combine advantages of the MIMO and phased-array radars. In these radars, the transmit array will be partitioned into a number of subarrays that are allowed to overlap and each subarray transmit...

Modern microwave and millimeter wave phased array antennas are attractive because of their ability to steer wave beams in space without physically moving the antenna element. A typical phased array antenna may have several thousand elements fed by a phase shifter for every antenna, which can steer the resulting array beam to different directions. Their low loss, low cost and lightweight phase s...

Planar antennas are common components in sensing applications due to their low cost, low profile and simple integration with systems. They can be used commonly at frequencies as high as 77 GHz and above, for example in automotive sensing. Also, new ultra-wideband communication systems operating around 60 GHz will heavily rely on planar antennas due to their unique properties. One special advant...
