The dipole Omni-directional antenna is used to gain radio frequency. Its ability to capture the frequency from all directions is the reason why it is so widely used. Before going to the specifications and features of this Omni-directional, RP-SMA antenna, let’s discuss what the dipole antenna consists of and how it is constructed.
What is Dipole Antenna?
The dipole antenna is the most simplest and most commonly used antenna to gain radio frequency. The word ‘dipole’ means having two poles. The dipole antenna has two poles and hence it is called as such. The two poles made from copper wires or rods are identical in size, thickness and shape. This makes the antenna characteristically balanced as it is bilaterally symmetrical.
Most commonly they have an RP-SMA-male connector that can enable an upgrade to a higher-gain antenna an a relocation of the antenna by using an RP-SMA cable.
Construction of Dipole Antenna. The dipole antenna is constructed using only a few basic materials.
The Positioning of Conductors
These conductors run parallel to each other having a continuous distance between them throughout their length. The lengths of these conductors are half the length of the frequency that they are going to generate. The frequency is fed in the connector between the two conductors. This antenna can be oriented in different directions; for example
- And even in slant directions.
What is an Omni-directional Antenna?
An Omni-directional antenna could be any antenna which is designed to receive or transmit signals from all directions. It is a more efficient type of antenna because it can intercept or radiate the radio frequency equally well in the various horizontal directions; therefore they are successfully employed for use with wireless routers and devices such as cellular phones.
Dipole Antenna Can Become Omni-Directional Antenna
It is possible for dipole antenna to serve as Omni-directional antenna. As discussed earlier the two conductors of the dipole antenna can be oriented in different ways to improve their efficiency. Therefore when the dipole antenna is oriented vertically, it exhibits Omni-directional properties in a horizontal plane. If the antenna is oriented slant ways, there is always a chance of obstruction in the transmission and in the receiving of signals. These obstructions are minimum when the antenna is fixed vertically and therefore the performance is enhanced.
Similarly if there were multiple vertical dipoles in a collinear disposition then they will possess Omni-directional properties. A few things that must be kept in mind is that the
- Dipole Omni-directional antennas should be grounded and
- It should be placed far from the devices that are going to receive the signals.
So, the Omni-directional antennas are, therefore, more efficient as compared to dipole antennas when it comes to transmitting and receiving signals in an azimuth plane. There are numerous gadgets and devices that depend upon optimum functionality of antennas that can send catch and transmit signals efficiently in all directions; a dipole Omni-directional antenna is, therefore, one of the best options.
