Maswell 6-in-1 4X4 5G MIMO Plus 2X2 MIMO WiFi7 Combo Antenna

Maswell has launched a new 6-in-1 5G combo antenna: AN.AG50.4Cell.2WiFi.2M (Figure 1).

The 5G combo antenna covers 5G 4X4 MIMO plus WiFi 7 2X2 MIMO applications. The cellular 5G part of the combination antenna is equipped with four independent cables, supporting 4X4 MIMO that covers almost all the 5G, 4G LTE as well as 3G spectrums in the world. It also supports all wireless communication protocols with a frequency range from 700 MHz to 6000 MHz, offering a maximum gain of 3.0 dBi with an omnidirectional radiation pattern.

The WiFi component of the combination antenna supports the 2.4 GHz, 5 GHz, 6 GHz, and 7.125 GHz frequency bands, with a frequency range from 2100 MHz to 7200 MHz, a maximum gain of 3.0 dBi, and an omnidirectional pattern. This 6-in-1 combo antenna can meet all WiFi wireless communication needs.

The Measured Reflection Coefficient Results

The fully measured reflection coefficients S11, S21, S31, and S41 performances of the 5G antenna section are illustrated in Figures 2 through 5 for operational bandwidth verifications. The measurement with the vector network analyzer (VNA) is set at a start frequency of 500 MHz and a stop frequency of 8.5 GHz.  As shown in Figure 2, the S11 of the antenna remains below -5 dB for most of the 700 MHz to 7.2 GHz span, and all of the frequency bands measure below -4.5 dB. These results confirm the impedance bandwidth and operation capability of the antenna for 700 MHz to 7.2 GHz, which is wider than the required 700-6000 MHz 5G applications.

In order to further verify the isolation between the four different ports of the antenna, the S21, S31, and S41 of the antenna were measured. As illustrated in Figures 3 to 5, the isolation between the various ports of the antenna remains 10 dB or better for the entire 700 MHz to 7.2 GHz spectrum. These isolation performances confirm that the 5G radiators inside the antenna may operate independently with the MIMO communication channel quality being maintained across the spectrum.

The fully measured reflection coefficients S11 and S21 of the WiFi antenna frequency band are illustrated in Figures 6 and 7 for operational bandwidth verifications. The measurement VNA was set at a start frequency of 2.1 GHz and a stop frequency of 7.2  GHz.  As shown in Figure 6, the S11 of the antenna remains below -8 dB from 2.1 GHz to 7.2 GHz.  These results confirm the impedance bandwidth and operational capability of the antenna for the WiFi 2.4-7.2 GHz bandwidth.

The Measured Radiation Pattern Results

The E-plane pattern and H-plane pattern of the AN.AG50.4Cell.2WiFi.2M in the 5G low frequency band (800 MHz) and relative frequency band (3500 MHz) are shown in Figures 8 and 9.

For WiFi radiators, the E-plane pattern and H-plane pattern of the AN.AG50.4Cell.2WiFi.2M in the WiFi low frequency band (2400 MHz) and relative frequency band (5800 MHz) are shown in Figures 10 and 11.

Based on the simulated and measured results above, the AG50.4Cell.2WiFi.2M not only has good signal reception capacity in an outdoor environment but also has excellent operational bandwidth performance for various applications, which is highly suitable for omni-directional applications.

Antenna Installations

Installation of this product is via direct M28 screw mounting with 3M adhesive under the radome as the reinforcement mounting. This is simple and secure. As shown in Figure 12, the AG50.4Cell.2WiFi.2M may be mounted on a cabinet with screw and nut fastenings (b) and using a 3M adhesive membrane (a).

Additionally, an L shape bracket (part number: AN_MASTER_CUBIC-UBOLT) is available separately for U bolt pole or right angle wall mounting.  The AN_MASTER_CUBIC-UBOLT installation kit comes with the L bracket, U bolts, and screws for various installation scenarios (Figure 13).
