although this is not necessarily required, and may comprise any antenna type, e.g., a wire antenna, dipole, patch or a horn aperture. The spacing of the elements is typically periodic. The composite radiation pattern of an array antenna array is determined by the vector addition of the elec...
A folded dipole antenna(1) includes a base substrate(10), a first radiation element(30), a second radiation device(40) and a disc(50). A first radiation element is formed on the base substrate. The first radiation element receives the RF(Radio Frequency) signal and a DC control signal....
An example of such multiband antennas is disclosed in PTL 1. A multiband antenna disclosed in PTL 1 is configured with a plurality of dipole antenna elements each of which is tuned to a different frequency band. The multiband antenna is configured by alternately arraying crossed-dipole antenna e...
While important for building physical models of wave propagation in wireless networks, this method can be used more generally to determine the magnitude and phase of an electromagnetic wave at every point in space, as well as usher in the era of drone-to-ground and drone-to-drone ...

The drawback of using ground planes, where EMI is of concern, is the creation of a dipole antenna structure which can radiate differential voltages formed between GND1 and GND2. If ground planes are used it is recommended to minimize their area, and use contiguous planes as any openings or...
