    Waveguide slot antennas are a type of microwave antenna that use a hollow metal tube, called a waveguide, to transmit and receive electromagnetic waves. They have slots cut along the length of the waveguide, which act as radiating elements. Waveguide slot antennas have some advantages over other types of antennas, such as high efficiency, low loss, and wide bandwidth.

    A new design of circularly polarized (CP) patch-helix hybrid antenna with small ground is presented. The proposed antenna consists of a driven patch, a parasitic patch, and a helix connected with the parasitic patch. The hybrid antenna has a relatively small ground, making the overall antenna compact. The proposed antenna can be packaged in a thin cylinder and can be easily mounted in the space-limited systems. Good impedance matching was achieved by capacitive coupling between the driven patch and the parasitic patch, while high gain was obtained with a small ground due to relatively uniform current along the helix.

    Petra-10 MIMO 4x4-Universal compact panel antenna for 4G / 5G modems and routers that support MIMO 4x4 technology. F=1700-5000MHz, CU=7-12dBi, connectors 4 x N-female, X-pol, decoupling between channels of more than 20dB.

     The PETRA-10 MIMO 4x4 panel antenna is designed for use in a set of equipment for 4G (B1, B3, B7, B38, B40) and 5G (N77, N79, N78) wireless data transmission systems at frequencies of 1700-5000 MHz.
    This antenna is compatible with MIMO 4x4 equipment, as it has four connectors for connecting to the equipment. You can also connect two modems with MIMO 2x2 technology to the antenna for redundancy/summation of communication channels.

                     Advantages of the PETRA-10 MIMO 4x4 antenna :

    The wide band of the antenna allows you to work in all current and future fastest cellular communication bands

    Full support for MIMO 4x4 technology.

    Active emitters are reliably protected from precipitation by a housing made of UV-resistant plastic and have an extended service life

    The antenna inputs are short-circuited by direct current between the external and internal conductors, which reduces the probability of static electricity accumulation at the modem input and makes the use of a lightning arrester optional (with a small length of the connecting feeder between the modem and the antenna).

           Electrical characteristics 

    Operating frequency range, MHz 1700÷5000

    Gain factor, dBi 7.0÷11.5

    Bottom width in the H-plane, deg 47÷73

    Bottom width in the E-plane, deg 46÷72

    Decoupling between ports in the operating range, not less than 23 dB

    Input impedance, Ohms 50

    SWR in the operating frequency range at the inputs, max. 1.8

    Permissible power, W 10

    Slope of polarization of received / emitted waves -45°/+45°(X-pol) or 0° / 90°(V/H)

         Mechanical characteristics

    Antenna weight, g 1185

    Mounting on a pipe with a diameter of, mm 30-52

    Operating temperature range -60°C to +80°C
