While various methods for multi-band ES antenna designs have been explored, none have successfully achieved fully ES performance (ka 1 for all bands) for a quad-band design, as the increasing number ...

Agricultural machinery is revolutionising farming by automating tasks like planting, spraying, and harvesting with precision ...

Abstract: In this letter, a novel approach to reduce mutual coupling (MC) of quad-port circularly polarized (CP) microstrip patch antenna (MPA) is proposed using a multi-mode concept. Firstly, the ...

Its design is practical, however, and that’s where it really stands out for me. The SpotOn is designed so that the built-in Active GPS Antenna always faces skyward, so GPS signals don’t have to travel ...

It does not necessarily reflect the view of The Herald. POLICE have called in drones and helicopters to deal with the growing problem of anti-social quad bikers who are making the lives of Greebnock ...

Haivision has introduced its new Falkon X2 series, an all-new line of dual-modem, quad-antenna mobile video transmitters designed for live broadcast contribution over any network, including both ...
