24 GHz Active Phased Array Antenna for Microwave Sensors
نویسنده
چکیده
Microwave sensors are robust non-contact measurement devices for industrial and vehicular application. Phased array-antenna modules, located in the front-end of the sensor, are often used to enhance the performance of this device. In this paper, a novel 24-GHz microstrip linear array antenna with beam-scanning and signal-amplification properties are presented. The phase shift section is designed using digital and analogue phase control properties, to minimize the requirement of complicated control circuits and large external biasing magnet .

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...
متن کاملPhased 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 ...
