Industrial Wireless Wireless Antennas and Accessories Overview Moxa’s antennas are specifically designed for long range applications. Additional aftermarket antennas are used to extend the wireless range. Selecting the right antenna system can greatly enhance transmission coverage and power. This page briefly explains the differences between the two basic types of antennas: omni-directional and directional. The two types are categorized by the direction in which they beam radio signals. Omni-directional Directional Omni-directional antennas are designed to radiate signals equally in all directions. They have very limited vertical spread, which determines the antenna gain. Antennas of this type are typically located in the center of open spaces or larger offices to provide even coverage to all clients. Omni-directional antennas are the right choice for applications that require constant location changes. Directional antennas provide a more focused signal than omnidirectional antennas. Signals are typically transmitted in an ovalshaped pattern with a beam width of only a few degrees. With higher gain, directional antennas can also be used outdoors to extend point-to-point links over a longer transmission distance, or to form a point-to-multipoint network. Types of Directional Antennas Types of Omni-directional Antennas H-plane E-plane Fiberglass Antenna H-plane Panel Antenna Antenna Connectors Before you purchase an antenna for your wireless device, you should check the type of antenna connector that your device uses. You will need to buy an antenna with a matching connector. There are several types of antenna connectors, including MCX, TNC, N-type, SMA, and N-type (male) N-type (female) RP-SMA (female) RP-SMA (RP stands for “reverse polarity” or “reverse ping”). On WLAN devices, the most commonly used antenna connectors for IEEE 802.11 applications are RP-SMA and N-type. Make sure to check the connector type of before you buy an antenna RP-SMA (male) SMA (female) SMA (male) Choosing the Right Antenna for Your Project If you are planning to extend the range or widen the coverage of your wireless connection, then you may need to use external high-gain antennas for your access points. In addition to the antenna type and gain, there are a few other specifications that you should consider. Frequency Range Equivalent Isotropically Radiated Power (EIRP) The most important parameter of an antenna is its working frequency. If you use a 2.4G antenna for IEEE 802.11a applications, you will find that the signal is too weak and the data rate drops down to a very low level. Be sure to use the right antenna for your planned working frequency. The EIRP value is defined as the power transmitted by a theoretical isotropic antenna that distributes power evenly in all directions and emits and produces the peak power density observed in the direction of maximum antenna gain. Local governments control the EIRP of radio devices under radiation/telecommunication regulations. You must ensure that your wireless system does not exceed legal EIRP values. The EIRP value is also used to estimate the service area of the transmitter and to coordinate transmitters on the same frequency so that their coverage areas do not overlap. EIRP is calculated by measuring the power of the transmitter, losses in transmission lines and connectors, and the gain of the antenna. The unit used for EIRP and transmitter power is dBm, cable loss is measured in dB, and antenna gain is expressed in dBi, relative to a (theoretical) isotropic reference antenna. Half-power Beam Width (HPBW) This parameter is measured from the antenna’s radiation pattern, and refers to the beam width at which the antenna’s radiation drops to half of its peak value. It also refers to the antenna’s effective coverage area. Once you get outside the half-power beam width, the signal typically drops off very quickly. A very high-gain antenna has a very narrowangled half-power beam width, which makes the directionality high as well. Antenna Polarity Polarization refers to the direction in which the electromagnetic field lines point as energy radiates away from the antenna. The simplest and most common type is linear polarization. When power is sent from transmitter to receiver, only that portion of the beam with the same polarization can be received. An improper antenna installation may decrease performance.
