How Does a Wi-Fi Antenna Work?

Table of Contents

Wi-fi antennas are designed to help people extend and boost the signal of an existing wireless internet source that’s either too far away or overcrowded to get a strong, usable internet signal. These antennas work by taking an existing wifi signal (coming from a campground, coffee shop, or other public signal source point), and repeating those signals on a private, password-protected VPN network that has enhanced power and signal strength – allowing you to make weak wifi signals usable.

Why are antennas of different lengths?

In wireless communication systems, antennas are used for both the transmitter and the receiver. These vary in length depending on the system. For example, a Wi-Fi antenna is shorter than the antenna of a stationary radio. But why is this the case? Why do communication systems not use the same antenna? The reason is that different frequencies are assigned to different services and systems. Wi-Fi communicates among others in the frequency range of 2.4 GHz or 5 GHz, an FM radio in the frequency range of 87.6 MHz – 108 MHz. The frequency is used to calculate the wavelength, which is decisive for the antenna length.

How does a Wi-Fi antenna radiate?

The shape of an antenna influences the radiation pattern. The simplest antenna shape is the omnidirectional or rod antenna. With antennas, a distinction is made between horizontal radiation and vertical radiation.

Why do Wi-Fi antennas have different shapes?

Antennas are manufactured in different shapes in order to specifically influence the radiation pattern. The antenna is designed to radiate field lines with good directivity. In addition, unused areas are not or only very slightly irradiated. Due to the directivity, the gain of the radiation is higher, accordingly, the range in this direction is also higher. In domestic use, simple omnidirectional radiators are used in most cases. The housing of antennas is often designed more modern by the manufacturer, but the content remains an omnidirectional radiator. In companies with large offices or halls, the choice of a different antenna shape can bring great advantages.

Do you need an antenna if you have WiFi?

Wi-Fi antennas are a great way to get a better internet connection and more coverage of your surroundings. They are commonly found on laptop computers but don’t just work with these devices. Wi-Fi antennas are available as USB adapters for any computer with a USB port. These adapters can increase your internet speed and stability while ensuring your system stays up and running.
