General aviation aircraft antennas for the global positioning system

Several antenna designs that utilize the NAVSTAR Global Positioning System in a low-cost system for general aviation aircraft were evaluated. Experimental investigations were made of crossed-dipoles, various types of crossed-slots, and microstrip antennas with modifications to improve their coverage. Principal plane radiation patterns for several of these antennas were measured on a one-seventh scale model of a Gates Lear Jet

MLS antenna locations for the deHaviland DASH 7 aircraft

Several proposed aircraft antenna locations were investigated to determine their potential for satisfying the microwave landing system antenna coverage requirements. The results of this investigation are presented and antenna locations are recommended for the deHavilland DASH 7 aircraft

Beta-lysine Discrimination by Lysyl-tRNA Synthetase

Elongation factor P is modified with (R)‐β‐lysine by the lysyl‐tRNA synthetase (LysRS) paralog PoxA. PoxA specificity is orthogonal to LysRS, despite their high similarity. To investigate α‐ and β‐lysine recognition by LysRS and PoxA, amino acid replacements were made in the LysRS active site guided by the PoxA structure. A233S LysRS behaved as wild type with α‐lysine, while the G469A and A233S/G469A variants decreased stable α‐lysyl‐adenylate formation. A233S LysRS recognized β‐lysine better than wildtype, suggesting a role for this residue in discriminating α‐ and β‐amino acids. Both enantiomers of β‐lysine were substrates for tRNA aminoacylation by LysRS, which, together with the relaxed specificity of the A233S variant, suggest a possible means to develop systems for in vivo co‐translational insertion of β‐amino acids

An on-chip W-band bowtie slot antenna in silicon

This paper presents a W-band fully on-chip bowtie slot antenna over a grounded low resistivity silicon substrate fabricated in 180 nm BiCMOS process. The measured results show that the proposed antenna could provide a wide input bandwidth covering the whole W-band. The simulated gain at 90 GHz is 1 dBi when considering several realistic effects. © 2012 IEEE
