Efficient Calibration of Active-Phased-Array SARs
Calibration of the first space-borne SAR instruments, with only one swath and based on passive antenna technologies, (e.g. ERS-1) required the in-flight characterisation of that single-swath instrument over well-known scatterers (reflectors, transponders and rainforest sensing data). Modern systems evolved to more access flexibility -therefore, multiple beams-, and multi-polarisation that led t...
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 ...
متن کاملRF EMF Exposure Compliance of mmWave Array Antennas for 5G User Equipment Application
In the millimeter-wave bands towards 5G, human exposure to radio frequency (RF) electromagnetic field (EMF) is evaluated in terms of free space power density, rather than specific absorption rate. Maximum power density emitted by 5G user equipment should not exceed the power density limits set by relevant regulatory guidelines. In this paper, we provide upper bounds of maximum power density of ...
متن کاملA Trinary-Phased Array
A trinary-phased array, in which a phase quantization unit of phase shifters is 120 degrees is examined. The phase quantization unit of 120 degrees is the roughest value in practical phased array applications. Despite its rough phase quantization, the sidelobe level of less than −9 dB is attained by a genetic algorithm approach. key words: phased array, trinary phase shifter sidelobe reduc-
متن کاملmilliProxy: a TCP Proxy Architecture for 5G mmWave Cellular Systems
TCP is the most widely used transport protocol in the internet. However, it offers suboptimal performance when operating over high bandwidth mmWave links. The main issues introduced by communications at such high frequencies are (i) the sensitivity to blockage and (ii) the high bandwidth fluctuations due to Line of Sight (LOS) to Non Line of Sight (NLOS) transitions and vice versa. In particula...
