Disclosed herein are implementations of devices and methods for side mounting of microelectromechanical systems (MEMS) transducers on tapered horn antennae. A hole is made in a sidewall of a tapered horn antenna, where the hole is substantially cylindrical, tapered and the like. In an implementation, an internal port opening of a MEMS microphone is aligned with the hole and attached to the sidewall of the tapered horn antenna. In an implementation, the hole is tapered with a diameter at one end, either the same or slightly larger than the diameter of the port opening of the MEMS microphone and a larger diameter at another end of the hole. In an implementation, a tube is used to connect the internal port opening of the MEMS antenna to the hole in the tapered horn antenna. In an implementation, the tapered horn antenna may have multiple holes, each having its respective MEMS transducer.
