A Ka-band 8-channel TX Active Module Design for Active Phased Array Antenna

Ka Band Transmit Antenna Array

Active antenna arrays working at higher frequencies result in higher packaging densities. The antenna array under consideration operates at about 30 GHz and will be installed in an aircraft. Commercially available power amplifiers at these frequencies have an efficiency of typically 20 %, which results in high amounts of dissipated heat for the required high radiated power. The dissipated power...

24 GHz Active Phased Array Antenna for Microwave Sensors

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 designe...

T/R Module Performance Monitoring of the TerraSAR-X Active Phased Array Antenna

The German remote sensing satellite TerraSAR-X, launched in 2007, hosts a flexible XBand synthetic aperture radar (SAR) operating in Stripmap, Spotlight, ScanSAR, and additional experimental modes. For these various antenna beams, its active phased array antenna electronically steers and shapes the patterns in azimuth and elevation direction. The array consists of 384 radiating sub-arrays for h...

Design, Simulation and implementation of active dual-band dipole antenna using a series stub

In this paper, a new method for designing an active dual-band dipole antenna is proposed. The operating frequencies of the proposed antenna are 150 and 450 MHz that are usually used in military applications. Using a series stub is the main idea in the proposed dual-band antenna, where it makes an independent resonance frequency higher than the main resonance frequency of a conventional dipole. ...
