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

, 2019 This paper present the dielectric rezonator antenaa (DRA), what does it mean, how to design it, how do we calculate the resonant frequency. While designingDRA with the toolkit HFSS, the main goal was to present how to design a DRA, and to see how to achieve specific needs by manipulating the dielectric constant or the dimensions of the DRA.
