Sentence examples for antenna concentrates from inspiring English sources

As a directional antenna concentrates the transmit power into the main lobe direction, the radiation intensity in the main lobe direction is larger than that in other directions and its in that direction is much larger than zero.

However, a directional antenna concentrates the energy on a certain direction, i.e., the cone as shown in Figure 3. Thus, by the definition of the antenna gain, we have frac{G_{m}}{G_{o}}=frac{frac{P}{A}}{frac{P}{S}}=frac{frac{P}{pi r^{2} tan^{2}frac{theta}{ 2} } }{frac{P}{4pi r^{2} } }=frac{4}{tan^{2}frac{theta}{ 2}Figure 3 The radiation pattern of a directional antenna.

All practical antennas concentrate the radiated energy in some directions at the expense of others.

In a DIR network, a node equipped with a directional antenna just concentrates its transmission to a certain direction, as shown in Figure 7. Thus, only cells covered by the antenna beam of the directional antenna can be interfered (the blue squares in Figure 7).

In these the loops are replaced by improved antennas that concentrate the radio waves into narrow beams a few degrees wide; the dots and dashes are replaced by more sophisticated patterns or modulations.

The improvement on the network throughput of a DIR network mainly owes to the reduced interference by using directional antennas, which concentrate the signals in some directions.

According to the explanation of LSPR in metallic nanoparticles in the session of "LSPR biosensors based on nanoparticles", nanoparticles act as optical antennas that concentrate and localize the electromagnetic fields of the incident light with appropriate wavelengths.

By using array configuration, the array antenna showed more concentrating main beam in the radiation pattern and higher gain than the single-element antenna.

The highly concentrated antenna dye molecules absorb the excitation light and transfer the energy to an indicator dye.

The antenna can be designed to concentrate the radio energy into a beam like a searchlight and so increase its effectiveness in a given direction (see electronics).

Here, the highly enhanced local fields mainly concentrate at the antenna walls and decrease along the x-direction within the gap region.
