He turned to an RTL-based TV Dongle. Since the stock antenna was not cutting it, he decided to make one specifically for the 1090 MHz signal. His design is based on Coaxial Collinear Antenna for ...

The course covers antennas and radiowave propagation in the frequency range above about 100 MHz. The antenna part covers basic theory, wire, dipole, apertures/horn, reflector, and microstrip, and ...

and microstrip antennas. The radiowave propagation part covers free space, reflection, transmission through materials, diffraction, effects by atmospheric gases, hydrometeor precipitation, and ...

Travel times of HF transequatorial propagation (HF-TEP) of signals of Radio Australia from Shepparton (36.2°S, 145.3°E), Australia to Oarai (36.3°N, 140.6°E), Japan, were measured by the system.

Frontiers requires authors to select the appropriate article type for their manuscript and to comply with the article type descriptions defined in the journal's 'Article types' page, which can be seen ...

Abstract: A graphene antenna with dynamical control of radiation pattern is proposed in this article. The device consists of a dipole with two coplanar graphene parasites. Working in the frequency ...

The Berrimah radar is located on a rise with the dish antenna tower mounted app roximately 50 metres ... some signal blockage to the north-northeast due to several HF transmitter towers. Heavy rain ...
