E-band and millimeter wave antennas
E-band and millimeter wave antennas for 5G communications bring three new
advantages: wider channels (increased data transmission speed), lower latency
(enhanced responsiveness), and stronger device connectivity (meeting the
connection needs of sensors and smart devices). Among them, E-band, as an
important part of millimeter wave, plays an indispensable role in the 5G era and
can be called a real innovative breakthrough.
E-band (71GHz to 86GHz) supports high-speed data transmission (about
10Gbps) within a short distance (2-3 kilometers).
At present, E-band antenna solutions have basically covered most of the
conventional needs in the market (as shown in the table below), with annual
global shipments exceeding 60,000 units.
E-band antennas always adhere to 100% full-field test delivery, and core
indicators such as gain are based on actual measured data, which firmly occupies
a leading position in the industry.
One of its outstanding advantages is the application of frequency band and
carrier aggregation (BCA) technology - this technology can effectively extend
the transmission distance of point-to-point links while improving reliability.
By combining low-frequency bands such as 15GHz, 18GHz or 23GHz with the E-band
through dual-band antennas, a link coverage of 7-10 kilometers can be achieved,
and the capacity can exceed 10Gbps. Since 2018, more than 3 mature dual-band
(multi-band) antenna solutions have been launched to support mainstream radio
equipment manufacturers around the world. The sizes cover 0.3 meters and 0.6
meters, and the frequency bands mainly include 5G, 11G, 13G, 15G, 18G, 23G, 28G
and 80G.
In addition, in the 5G era, there are other members in the millimeter wave
family that cannot be ignored. According to the "Wireless Backhaul Evolution
Report" recently released by GSMA, V-band and E-band are expected to achieve
significant growth in the next few years, with a compound annual growth rate
(CAGR) of 11.6% in all regions from 2021 to 2027. In fact, the total volume of
E-band links is expected to account for more than 70% of all mmWave links
(V/E/W/D) by 2027.
