Active Phase Conjugation with Multiple Antenna Array Element
In this paper we analyze the temporal and spatial compression characteristics of retrodirective antenna systems wherein active phase conjugation (APC) is deployed. It is shown that under the active phase conjugation Hermitian channel matrix properties result and these lead to opportunities for both temporal and spatial signal compression. The effects of additive channel noise, as well as compre...
متن کاملA Low-profile Active Phased Array Antenna System for Mobile Direct Broadcasting Satellite Reception
1. Introduction A direct broadcasting satellite(DBS) service via Koreasat 3 is currently provided and there are many subscribes for a residential house. In addition, many people want to watch the DBS TV even at vehicles because it has advantages over terrestrial TV broadcasting with high quality, simultaneity, wide coverage, and so on. Several antenna systems for mobile DBS reception have been ...
متن کاملSingle-element based ultra-wideband antenna array concepts for wireless high-precision 2-D local positioning
We generally categorize the approaches for ultrawideband antenna array design, and consequently propose simplified concepts for antenna arrays for a high-precision, ultra-wideband FMCW radar 2-D local positioning system to obtain robustness against multi path interference, perform angle of arrival analysis, as well as instantaneous heading estimation. We focus on low-cost and mechanical robust,...
متن کاملDesign and Simulation of Patch array antenna for Indian Regional Navigation Satellite System [IRNSS]
The modern mobile communication systems requires high gain, large bandwidth and minimal size antenna’s that are capable of providing better performance over a wide range of frequency spectrum.This paper presents the design of microstrip rectangular patch antenna with center frequency at 1.176GHz for IRNSS application. The array of four by one (1x4) patch array microstrip rectangular antenna wit...
متن کامل24 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...
