L-band and C-band microwave radar observations can help to measure the properties of snow cover on land by providing information about he soil-snow boundary condition. In this theoretical study, we xamine the sensitivities of microwave radar measurements to soil and snow characteristics, and we compare a simple model with previously published data. These data show that the thermal insulation pr...

Radars at different frequencies have been used over five decades for observing precipitation. S and C bands have been employed for long range coverage observations. Dual-polarization X-band radars have been shown to be useful for networked applications. Space borne precipitation radars have been at Ku band, or higher frequencies such as Ka, as in the GPM mission. This paper presents a comprehen...

This research proposes a development of embroidered dual band textile antenna that could integrate wearable telecommunication device with a garment. The proposed antenna could operate at 2.4 GHz and 5.8 GHz of WLAN applications. Two versions of the presented antennas are developed from the conventional rectangular patch. Two types of slot structures are loaded on each antenna and the antenna pe...

In this paper, a novel compact band pass filter (BPF) is proposed for Global Positioning System (GPS) receivers. The proposed BPF configuration is composed of a low pass filter (LPF) section formed by the coupled line transformer connected with a radial stub and two short circuited stubs embedded within the 50Ω microstrip line connecting the input/output (I/O) port of LPF. The lumped equivalent...

This paper presents results of the new investigation of proposed antenna design based on the T shape at the 17.87GHz in application to perspective Ku band. This result is based on the work of computer simulation technology software. The design approach combines application in satellite and radar applications. A simple geometry of the proposed antenna geometry is shown to be composed two rectang...
