One example includes a method for assembling a reflector antenna. The method includes coupling first and second frame members to respective sidewalls of a panel bonding tool via fastening features to engage a through-hole pattern of each of the respective frame members and bend the frame members to form a perimeter frame. A longitudinal surface of each of the frame members corresponding to a reflector profile of the reflector antenna extends beyond a longitudinal surface of the respective sidewalls along a length of the respective sidewalls. The method also includes applying an adhesive to each of the frame members of the perimeter frame, and adhering a reflector skin to the perimeter frame to form a radial antenna panel. The radial antenna panel has the reflector profile. The method further includes decoupling the radial antenna panel from the panel bonding tool upon curing of the adhesive.

This document discloses a reflector antenna system with movable MIMO multiple feeds and adaptive field focusing method for wireless communication in multipath fading environment; the system comprises antenna reflector, multiple feeds, the equal number of the signal receiving channels and signal transmitting channels to the feeds, all the channels are capable to measure and adjust the amplitude and time delay of signals, and the method for amplitude and time delay adjustment of the powered signals. In signal receiving mode the antenna system makes the signal components arrived through unknown multipath superimpose synchronously; in signal transmitting mode, the system let the wave components radiated from different transmitting channels superimpose synchronously, realizing adaptive field focusing at the antenna of the communication target.

The invention is a dual and stagger-tuned 8-step FZP antenna for use in VSAT operations. The preferred embodiment achieves the desired antenna gain at the RX band (centered at 11.95 GHz) and the TX band (centered at 14.25 GHz). The flexible antenna is 1-meter diameter and less than 1-inch thick, allowing it to be folded to the size of a tissue box for easy storage and transportability.
