Radar Cross-section Reduction of Antennas Using a Stop-band Frequency Selective Surface

A novel stop-band frequency selective surface (FSS) is presented. By adding four narrow branches to conventional square-loop FSS, the proposed FSS can achieve a good frequency stability for different oblique angles and a high frequency selective ability. An equivalent circuit model is used to analyze its transmission property. Due...

Single-supply, TTL-level Gate Switching and Radiation Hardening by Design Using E-PHEMTs

Enhancement-mode PHEMTs significantly extend the usefulness of GaAs RFICs for general-purpose RF component designs. To demonstrate the technology’s benefits, this article demonstrates a 2 to 3 GHz GaAs PHEMT RF pulse modulator operating off a single, positive supply voltage, switched by a TTL-level logic signal. Active gate bias networks,...

A Unidirectional Horn-shaped Bowtie Antenna for Ultra High Resolution Radar

This article presents a high-performance unidirectional bowtie antenna backed by a corner reflector, which has a high-directive radiation covering over 100 percent bandwidth of the whole ultra-wideband (UWB) frequency band. This design implements a hor...
An ultra high resolution radar is one of many promising areas of UWB applications because of its inherent nature of ultra wide bandwidth.1 In theory, UWB radar could achieve the ultra high range resolution of up to 2 cm if a single antenna could cover the whole UWB frequency...

PhaseTrack II: Thermally Stable Coaxial Cables

Phase stability with respect to temperature has a direct impact on system performance and is therefore an important characteristic for high frequency components and subassemblies. Enhanced phase tracking with temperature translates into lower residual noise and reduced system uncertainties. Cable assemblies interconnecting critical high frequency signal paths will also...
