An array antenna comprising a plurality of antenna elements, multipliers for multiplying coefficients with transmission or reception signal and a calculator for calculating the coefficients for each multiplier. The calculator generates the coefficients in a proposed method such that the beampattern of the...
Phased array antennais developed using multiple antennas on a common PCB or plane. The antennas used here are patch antennas or dipole antennas in a array. This combination of multiple antennas help improve gain as well as directivity. Individually all the antennas of the array are controlled and...

especially if your a Never-Quad ...Yagi Antenna guy. That's capture area or effective area of the antenna. This is NOT the size of the antenna. Since a cubical quad loop is twice the size of a yagi dipole, you would think it has twice the capture area. That is incorrect. The capt...
patch antenna array design A patch antenna radiates as a wide, open half-wave microstrip resonator, and it consists of many individual patches arranged on a dielectric substrate. This antenna has several advantages, including a higher degree of directivity and an overall low cost. It is an ideal...
Apparatus for improving the performance and allowing increased directionality of reflecting-type antenna systems by varying the geometry of the reflecting surface. A reflecting surface is composed of an array of actuated pins which are capable of extending or retracting to alter the overall pattern. An...
The controller104A may be further configured to monitor and collect RF communication environment information, such as propagation environment conditions, link quality, application device capabilities, antenna polarization, radiation pattern, antenna spacing, array geometry, transmitter/receiver locations, target...
An error calibration and compensation value calculator calibrates an error of the antenna array from the feedback signal, calculates a compensation value for compensating for the error, and provides the compensation value to the multiplier. 展开 ...
Furthermore the present matter describes a multi antenna array comprised of two or more of the multi-radiation element antennas, wherein the antennas of the array also exhibit high isolation. In accordance with a first aspect of the present matter there is provided a multi-band antenna comprising...
In some embodiments, sector antenna 31 is comprised of one or more antenna elements similar to antenna elements 30 in smart antenna array 28. In the embodiment shown in FIG. 1, antenna unit 18 is located on an antenna tower 22. However, antenna unit 18 may be otherwise located, for ...
