Integral flat antenna QFPA50

Quick Flat Panel Antenna

The QFPA is a portable, auto-plate all-in-one satellite antenna, whose panels are manufactured by waveguide mixed plate array technology. Under the control of the servo system, QFPA can complete satellite automatic pointing and accurately point and track satellites. The antenna can be controlled by a button.

The antenna panel is a single plate structure that supports full duplex communication in the VSAT network. The servo system provides fully automated functionality with one button control for antenna placement, satellite search, accurate pointing, automatic tracking, and storage. Alignment errors due to antenna initial heading and tilt during satellite pointing can be corrected automatically using the servo system. One person can finish antenna setup and satellite points in four minutes.

The antenna panel, servo system, LNB, and BUC are integrated into one chassis to form an all-in-one antenna system. Mechanical optimization effectively reduces antenna size and weight. When storing the antenna, all elements are stored in a wheeled case with a pull carrier that is easy for the user to carry and move. In addition, the case cover can be used as an antenna base that applies to the placement of antennas on snow, grass, and mud floors.

High gain reputation with low side lobes

QFPA is based on the plane layout of many waveguide horn antennas. Each waveguide horn antenna in the panel is an independent combination of small waveguide horn and mini antenna, which is the primary antenna element and supports dual frequency, dual biased and dual communication

Two parallel supply structures in parallel configurations are used to connect the RX and TX ports individually in each element from OMT to LNB and BUC. In the power supply circuit network, the antenna panel divides the RF signal, which is transmitted 16*16, into equal power, and the impedance matches well. In addition to the basic antenna elements, the power supply network is made of waveguide

QFPA provides much higher efficiency than a typical parabolic reflector antenna because of the low RF transmission loss on the wave. A high gain is achieved with the aperture of the antenna fixed, and a small aperture is created when the gain is constant. With a panel size of 50*50 cm, the QFPA is the same as the 0.65-0.7 m parabolic reflector antenna under the same gain conditions.

The QFPA antenna panel consists of 16*16 primary antenna elements. That is, there are 256 independent variable groups on the surface of the panel. By adjusting these variables, you can control the field strength distribution on the panel to optimize the desired transmission pattern with a side lobes much lower than the common reflector antenna, which can only use a close uniform field strength distribution.

For reflector antennas, the CCIR issued a requirement of -14 dB on the first side lobes. QFPA is a special field distribution design that allows the first segment of -22 dB and is much better than the CCIR standard. A very low side lobes can operate small flat antennas with high power amplifiers that have less interference with other satellite communications
