Agrupamentos de antenas planares

, 2016
O trabalho tem como objetivo ilustrar várias topologias de antenas planares, assim como de que forma é possível as agrupar (antenna arrays ou agrupamentos de antenas). Além disso, vai ser implementado um array de antenas deste tipo (simulações e, se possível fabrico da respetiva PCB) com uma aplicação muito concreta, FMCW RADAR (serão apresentados os ...

GPS-antena Zephyr Geodetic

Geodetski list, 2009
The paper describes physical properties and improvements of the GPS-antenna Zephyr Geodetic. It enables very precise measurements, with very small disturbances because it reduced the influence of multiple effects. Apart from that, the antenna has got more enhancing items so that there are lees signal delays present. From the comparison the antenna with
