PCTEL's 5-port base station omnidirectional antenna (BOA) is designed for fixed public and private LTE and industrial IoT network deployments.
Many WISPs begin with an omnidirectional antenna and a single radio to serve only a handful of clients.
To illustrate the GO shaping technique described in Section 2, the first case study is an ADE-like configuration designed with uniform amplitude distribution ([G.sub.A] = cte.) over the conical aperture, in order to increase the directivity of the omnidirectional antenna. The feed is a TEM coaxial horn with its radiation pattern described in [8] and modelled as follows in the present synthesis procedure:
The manufactured antenna, whose measured gain pattern is depicted in Figure 9, has about 3 dBi gain variation in this plane, which is still acceptable for an omnidirectional antenna.
The existing CH-based rendezvous schemes were designed with omnidirectional antenna according to different mathematical structures (e.g., [9-18]) in order to provide a successful channel rendezvous between a pair of single-hop SUs.

Two antenna patterns are taken into consideration, which are omnidirectional antenna and directional antenna with switching-beam.
It uses an omnidirectional antenna only briefly, and once it picks up a signal, switches over to directed beams aimed at the user's device.
This rugged omnidirectional antenna is designed for exceptional reliability in machine-to- machine (M2M) industrial wireless applications.
