You can use pretty much any Antenova antenna for a coexistance, and some antennas (such as SR4C034 Integra) are specifically designed for diversity applications. For more information, take a look at our Cat4 LTE Development Kit.
If you are using similar antennas for MIMO applications, refer to the data sheet for positioning and layout requirements to ensure better performance. Also check radiation patterns to prevent avoidable losses.
With most modern devices using multiple antennas at a time, it's incredibly important to choose the right antennas for the design. Antenova's antenna designs are created under the 'design for integration' principle, meaning they're compact and take up the minimum possible footprint within your design.
