Hace 7 horas · A Dual Linearly-Polarized Horn Antenna is a directional antenna that can simultaneously transmit and/or receive radio frequency (RF) signals in both horizontal and vertical directions or planes. The word polarization refers to the orientation or direction of the electric field of the RF signal. This type of horn antenna can support both types ...
Hace 7 horas · We have also created a ground station that’s associated with an antenna that has parameters in line with the antenna installed on satellites in order to minimize the information losses and transmit commands to the satellites, as well as a receiver having a circular polarization which can receive the wave regardless of the direction ...
Hace 7 horas · Lee et al. developed ultrathin metallic (metal filling ratios of > 70 %) metamaterials that exhibit perfect transmission at a specific radar frequency. These characteristics enable microwave ...
Hace 7 horas · For the communication module, a truncated-corners patch antenna with circular polarization is used which is connected to the TI CC2530 radio transceiver, integrating an Intel 8051 MCU, which adopts a protocol for communication named Simplicity.
Hace 7 horas · t. e. The cosmic microwave background ( CMB or CMBR) is microwave radiation that fills all space in the observable universe. It is a remnant that provides an important source of data on the primordial universe. [1] With a standard optical telescope, the background space between stars and galaxies is almost completely dark.
