Wireless power transmission presents itself as being a solution to some common problems of the extensive use of electronic devices such as the removal of parasitic components present in feeding pads and the constant charge of electronic devices without the need of wires. This solution becomes attractive, for example, as a means of increasing the flight time of battery dependent unmanned aerial vehicles...
Discone antennas are wide bandwidth and omnidirectional radiation antennas that are widely used in VHF and UHF broadcasting systems. This paper presents the design and implementation of a discone antenna, for indoor use in a digital TV receiving/transmitting system, which was developed using 3D printing technology, allowing the development to be simple, quick and less expensive. The antenna presents...
This paper presents the design methodology for the creation of corrugated horn antennas for the CosmoGal satellite. The mission will collect the radiation of the cosmic microwave background, by a radiometer in three different radio astronomy frequency bands (10.6–10.7GHz; 15.35–15.4GHz; 23.6–24GHz). It is discussed the design of several types of horns, simulated with the CST software. The best result...
Emerging vehicular communications are a key to combat several mobility issues, like road safety and efficiency. Dedicated short range communications (DSRC) is a wireless technology, operating at 5.9GHz, designed for automotive use. To operate, this technology has two types of devices, one for vehicles and another for roadside. This paper presents the design of an antenna for the vehicle unit of the...
Vehicular communications, among vehicles and between vehicles and infrastructures are based on wireless communication technology known as dedicated short range communications (DSRC), which are in great development with the aim of reduce the traffic problems and improve the road safety. This study is based on the development of a solution to an antenna to be used in the mobile module, usually named...
