What is the Magic Behind WiFi Antennas?

It is vital in today’s digital world to make the most out of the Internet. And we know this is true, for the benefit of both the private and business sectors. Every computer, every smartphone, and every computer printer you have — they all need to get hooked up, preferably wireless, over the Internet.

A gamut of issues will come to the surface though if we will bombard our wireless network with more wireless devices than it can manage to accommodate. Such a scenario will run the risk of compromising your Wi-Fi signal, causing your network to suffer from the poor signal. 

Under such scenarios, what can we do to increase the strength of the Wi-Fi signal? What aspects of the immediate environment must be taken into consideration? Is there really a way to remedy the situation? 

The Reason Behind the Variance of Lengths of WiFi Antennas?

In a wireless communication system, antenna applications can be found in both the receiver and transmitter. And with respect to the system, the length they come in can vary.

A Wi-Fi antenna, for example, is shorter than the antenna of a fixed radio. However, why is this so? Why aren’t all communication systems equipped with the same antenna? 

Perhaps the best expansion we can provide here is that different systems and services have been allotted with different frequencies. Wi-Fi transmits at frequencies starting from 2.4 GHz up to 5 GHz, while an FM radio can work from 87.6 MHz – 108 MHz.

Perhaps the best reason that will best explain this is that different systems and services have been allotted with different frequencies. Like, for instance, WiFi antennas transmit at frequencies of 2.4 GHz or 5 GHz, while an FM radio requires a frequency range between 87.6 MHz up to around 108 MHz to work seamlessly. The frequency can help determine the wavelength, and this is critical for antenna length calculation.

The wavelength reduces as the frequency increases. To achieve a favourable reflection to radiation ratio, popularly known as 𝛌/4, radiators are frequently utilized to lengthen the antenna.

Thus, for 2.4 GHz Wi-Fi, the antenna length should be approximately 3.1 cm. This translates to 78 cm long for the 𝛌/4 version of a radio with a frequency of 95 MHz. This is why Wi-Fi antennae are smaller in length when placed alongside radio antennas.

Why Do WiFi Type of Antennas Come in Different Shapes?

Antennas come in an array of sizes and forms, so they can impact the radiation pattern in a very specific way. The antenna is constructed in such a way that it radiates field lines with a high degree of directivity. Moreover, the unused regions are neither irradiated or are irradiated very marginally. 

Because of its directivity, the radiation gain is much bigger than anticipated, and hence the range is likewise should be greater in this direction. 

What is the Proper Way to Position Your WiFi Router? 

The placement of the router together with all the inked antennas has a crucial role to play in covering different rooms with strong signal strength. For this, it is recommended to evaluate first the antenna radiation patterns. 

Before you start installing your router, you need to predefine where Wi-Fi reception should be extremely good and strong. The location should then be adjusted such that the defined areas are as effectively lighted as feasible.

In the case that your router comes only with a single antenna, one will need to decide whether the same floor it is on or the rooms directly below/above would be served or not. 

It is highly recommended that you make use of a device that comes with more than just one adjustable antenna to circumvent this constraint. This will make it possible to extend the coverage area.
