Introduction to CBRS
CBRS presents as a significant venture in wireless communication offering a shared spectrum that balances accessibility, flexibility, and efficiency. Spanning between the 3.55 GHz – 3.7 GHz range the CBRS spectrum provides a cost-effective alternative to traditional carrier-based options in deploying private LTE and 5G networks.
CBRS antennas act as the driving force of the advancements credited to the CBRS domain. These antennas ensure high speed, low latency connectivity which makes them an essential element in both present and future wireless communication ecosystems.
What is the CBRS Spectrum?
The CBRS band is a 150 MHz bandwidth from 3.55 GHz to 3.7 GHz, exclusively available in the United States and regulated by the Federal Communications Commission (FCC).
Designed as a flexible resource for applications like private mobile networks, macro network extensions, and fixed wireless access the CBRS operates under a three-tier system to ensure efficient usage. At its topmost tier are the incumbent users, such as the U.S. Navy and satellite ground stations, fully protected from interference. Next are the Priority Access License (PAL) users, who have purchased access rights to 10 MHz channels with a duration up to three years. Lastly, the General Authorized Access (GAA) users are able to access the band under a small monthly fee, given that they do not interfere with higher-tier users.
In order to avoid access conflicts, the Spectrum Access System (SAS) mandated by the FCC coordinates usage between tiers, enabling CBRS to accommodate a variety of applications while nurturing innovation in wireless communication.
What is a CBRS Antenna?
CBRS antennas are specially designed for applications within the 3.55 GHz to 3.7 GHz bandwidth, also known as Band 48. These antennas come in a variety of configurations such as directional, omnidirectional, sector, and panel designs. This diversity in design enables effective coverage both indoors and outdoors, as well as mobile connectivity for vehicles, thereby improving overall network capacity and efficiency.
As many businesses, institutions, facilities, and worksites set up private LTE and 5G networks using the CBRS spectrum, these antennas play a crucial role in delivering high-speed connectivity tailored to each organization’s specific needs. Furthermore, as these antennas support use cases such as IoT device integration, smart manufacturing, and campus-wide wireless coverage, they have become essential components in advancing digital transformation.
CBRS antennas provide a cost-effective alternative to traditional carrier-managed networks, enabling users to unlock the full potential of the CBRS band. They offer improved data speeds, reduced latency, and enhanced network capacity in high-demand environments.
Types of CBRS Antennas
CBRS antennas are available in various types, each offering unique advantages in addressing different requirements within the CBRS band. Some of the key CBRS antenna types are as follows:
1. Panel Antenna
CBRS Panel antennas are directional antennas that feature a distinctive flat rectangular shape. These antennas usually offer gains ranging from 6 dBi to 18 dBi with horizontal beam widths of 30 – 120 degrees, making them ideal for targeted signal coverage.
As these antennas are able to focus radiofrequency energy in a defined narrow direction, they are widely used in cellular networks, wireless broadband, and in point-to-point communication systems in dense urban areas where there is a significant amount of interference.
2. Yagi Antenna
These antennas typically consist of a driven element, reflector, and several directors. Designed to provide long-range communication, these antennas offer gains between 7 dBi to 20 dBi with typical beam widths ranging from 20-50 degrees.
As Yagi antennas are able to produce a focused radiation pattern, they usually excel in forming point-to-point links, over-the-air media reception, and remote access where there is a need for stable, high-quality signals over extended distances.
3. Sector Antenna
CBRS Sector antennas are designed for applications requiring wide area coverage within the angular ranges of 60, 90, and 120 degrees.
As these antennas provide a high gain ranging between 10 dBi to 18 dBi, they can guarantee efficient signal transmission over large spaces, effectively reducing the number of antennas required for optimum coverage. Usually, multiple sector antennas are combined together to form cells in order to minimize overlap and interference in CBRS deployments.
These antennas can be designed to dual-polarized and support multi-input and multi-output (MIMO) configurations, they are ideally used in settings where high data throughput and reliability are required.
4. Fiberglass Antenna
Fiberglass antennas feature an omnidirectional radiation pattern and are encased in a durable fiberglass sheath, which enables them to endure harsh outdoor environments.
As these antennas are able to resist extreme weather conditions, UV radiation, corrosion, and high winds, they are usually used in marine communication systems, industrial monitoring systems, and in IoT networks where robust yet consistent performance is critical.
In addition to omnidirectionality, these antennas offer a decent gain ranging from 2 dBi to 12 dBi, making them good candidates for wide areas where the signal direction is subjected to variations.
5. Ceiling Mount Antenna
These antennas are omnidirectional antennas specially designed for indoor use.
With gains varying between 3 dBi to 8 dBi, these antennas offer reliable connectivity across enclosed spaces such as offices, hospitals, and retail spaces, while easily blending with their low-profile aesthetic design.
Ceiling mount antennas are generally used in setting up distributed antenna systems (DAS), private LTE, and enterprise networks, as they provide the best coverage options indoors.
6. Rubber Duck Antenna
Rubber duck antennas are specially designed compact antennas that are commonly used in portable devices for short-range communication.
Featuring gains between 2 dBi to 5 dBi, these antennas are commonly seen in handheld radio devices, IoT devices, and industrial sensors.
The rubber duck antenna features a helical coil that makes it a flexible and durable option that is able to resist physical stress and wear, making it a practical solution for portable CBRS-enabled requirements.

Integration with 5G Technology
The mid-band spectrum (3.55 GHz – 3.7 GHz) used by CBRS antennas offers 5G NR (New Radio) a balanced bandwidth between speed and coverage.
The CBRS mid-band spectrum is considered ideal as it is faster than the low-band frequencies used in older networks and also covers larger areas than mmWave (extremely high frequency) bands.
CBRS antennas are effective in expanding 5G coverage to areas ranging from densely populated urban cities to rural suburbs.
Furthermore, they can increase network capacity, enabling 5G internet to handle multiple devices at once.
As CBRS antennas use a shared spectrum model that prevents interference and is affordable, they help companies and institutions set up their own 5G networks for ventures such as factory automation, IoT devices, and smart agriculture in a cost-effective manner without facing interference from each other.
Furthermore, as CBRS antennas offer low latency and high data speeds, they can support 5G’s more futuristic applications such as augmented reality (AR), virtual reality (VR), and autonomous cars.
