In today’s fast-paced world, devices that use radiofrequency energy to communicate wirelessly surround us. Some of these devices like mobile phones or medical devices (heartbeat sensors) are held or worn close to our bodies. Others, however, allow us relatively unrestricted access to them as they transmit their signal through the air. WiFi antennas are one such example. 

Numerous devices can create Wi-Fi networks, but the critical part involves the antenna. For our purposes here, we will look at an antenna and the frequencies they use, and much more.

What is Wifi?

It is a wireless network connectivity technology. It is a network of wireless internet access points (APs) that create a wireless network of frequencies that ranges from 2.4GHz or using the new 5GHz technology, without using the old ethernet cable to access the Internet for devices such as computers, tablets, smartphones. WiFi networks are an essential part of people’s lives and much research and papers have been done about their benefit.

How does Wifi Work?

WiFi is a system of wireless communication to exchange information between devices that are close to one another. 

Wi-Fi networks transmit and receive data using radio waves. When you place a Wi-Fi network antenna on a device (such as your laptop or smartphone), the signal travels through the air and becomes a signal reaching your device. A device can then send and receive data through the network without the use of a tethered ethernet cable.

Wifi Frequencies

Megahertz MHz or Gigahertz GHz is the primary frequency unit of a wireless network. Wifi routers use the higher frequencies to create a wireless network that can reach speeds of up to 1300 Mbps (megabits per second)

There are two types of WiFi systems, Wifi 2.4 GHz and 5 GHz. The former provides better speeds and therefore more reliability when used with a mobile device. 

2.4GHz is primarily for connecting computers, tablets, and other gadgets to the internet, while 5GHz has more options for sports and other activities requiring high-speed internet access such as virtual training, live streaming, or high-definition video conferencing. 

However not every smartphone enables it to connect to a 5GHz network, due to the complexity and the cost of implementing the antennas to the devices.

What types Wifi Antennas ?


Omnidirectional wifi antennas or WIFI Antennas are used in different areas like those used by drone aerial photography. They transmit signals in all directions covering a large space.


Directional wifi antennas are like the missing link in outdoor networking. They point of the signal in a single direction but cover a much larger range in that direction leaving the side of the signal weak, which is most suitable if you’re trying to cover a specific place with radio frequencies 


Sector antennas are a combination of Omni and directional antennas. They do not need to be aligned in a specific direction and can be oriented in any direction. That is why they are called Omnidirectional antennas.

The strongest Omni-directional antennas are used in the aircraft world for guiding aircraft during takeoffs and landings. Aircraft manufacturers use these antennas to guide their engineers during numerous procedures that affect the performance and safety of the aircraft.

The Advantage of Using of Wifi

There are many advantages of using the Internet through a Wifi connection. You can do lots of things online without ever leaving your house.


  • you can check your email at work without having to wait for your partner to get home from work,
  • you can connect with friends and family around the world at the same time,
  • discover new content on the internet and learn skills in educational settings, all without needing any initial investment or distance from your home.

And finding a free Wifi network is not that hard these days. Most airports have free Wifi as part of their airport service. So do some research and see what airports offer their passengers. The same goes for fast-food chains, hotels, even some public transport systems.

Steps to Connect to a Wifi

Now that you know the basics of wifi, here’s how to connect to a wifi network around you.

  • First, you need a device that is capable to connect to the internet (i.e device with a Wifi antenna).
  • Second, you need to turn on the Wifi option, you check it by going to settings > Wifi Settings > Turn on Wifi
  • Third, you need to select the SSID or the name of the Wifi network the SSID stands for Service Set Identifier. This is the unique name that identifies a wireless network. The packet header keep the informitions while transmitting a pakcet .
  • Passwords protect the Wifi networks .
    • Wired Equivalent Privacy (WEP)
    • Wi-Fi Protected Access (WPA)
    • Wi-Fi Protected Access Version 2 (WPA2). 
  • The main thing you should know about these password protocols is that the newer you get, the harder for hackers to hack into your wifi network, 
  • Finally, after entering the password you should now be able to connect to the world wide web, and surf it freely while remembering The most important rule when surfing the internet is to stay safe. Never post anything you don’t want to print on your business card. Always be aware of the surroundings when using a computer or mobile device. 


Several factors come into play when you are searching for the best Wifi Antenna. You want an affordable device that will work with all popular wireless networks, coupled with high-performance reception. Additionally, you will want to make sure that this device meets your wants and needs. When you are doing your research, you should be able to narrow down your choices to one that fulfills all of your needs without exceeding your budgets.
