First, there is the gain of each individual element of our array (perhaps one patch), called the element factor (GE). Secondly, there is the impact that we can exert through beamforming the array, called the array factor (GA). The full array antenna gain pattern is the combination of ...
Whatever the complexity of the phased array antenna, whether it has just two elements, or a thousand, the basic principle is the same. As has already been mentioned it is based around the fact that when signals are in the same phase, they reinforce each other and when that are in the ...
PURPOSE: To reduce the antenna area of a phased array antenna. ;CONSTITUTION: Phase converters 62, 63 are connected with two (two pairs) feeding points which excite the same polarized wave of each microstrip patch antenna 61 forming a first sub-array antenna 6 via a diode. One of the feed...
effective in one direction or another. Directivity means that the signal is narrowly focused in one direction. This focusing of the signal is what creates the antenna gain.Figure 2showed the broad radiation pattern of a standard dipole and the radiation pattern (or lobe) of a phased array. ...
Phased-array antennas solve some of the problems associated with reflector-type antennas. For a given gain, the aperture of the phased array antenna is required to be about the same as the aperture of the reflector antenna. However, the phased-array antenna can be made as an essentially flat...
