How to Build a Low Cost wifi Antenna?

How to Make a WiFi Antenna for Laptop

Sometimes, your wifi signal doesn’t get where you want it to go. You’ve seen wifi adapters on the retailer; however, they are often expensive at your expense. We’ll show you How To Make A wifi Antenna For Laptop using shelf parts, no new software, and without opening your computer case. 

#1 Get a USB wireless LAN adapter “dongle”. 

This little device, about the size of your thumb, provides wifi capability in your computer. You’ll need it even if your laptop is wirelessly connected.

  • For best compatibility, get one that includes 802.11b and 802.11g standards.
  • Check out Google Commerce for reasonable prices – Simple pricing, which is quite useful at close range, costs 15 to 20 USD.
  • The shape is essential. For cost-effectiveness, find a small thumb-sized device. Larger “squashed mouse” models ($ 50-60USD) are usually more sensitive and powerful. Although they can be challenging to mount, they perform better in more demanding setups.

#2 Take a dish covered with mesh. 

The easiest to use Asian “scoop” is used for frying things in cooking utensils (such as wool-shaped, but mesh) – it is the most useful form and comes with an extended picket deal with!

  • Other options include steamers, sieves, pot lids, & lamp colours – as long as they are dish-sized and metal. Any parabolic piece of metal mesh will work – that means a better signal, but it’s harder to carry around.
  • More extensive options include discarded direct TV pots or umbrellas covered with mesh. Although they should receive more signals, increasing difficulty and wind resistance are approximately 12 inches (30 cm) (300 mm) in diameter. 
  • Flexible stalk desk lamps allow them to be neatly installed and positioned.

#3: Get a USB passive extension cable.

You want to type A (male) type A (female) cable. (You can find them at a dollar store, your local computer store, or Radio Shake). This will join the USB wifi adapter to your laptop’s USB port.

  • The antenna is directional to want its place, so it has a direct line of sight of the wifi entry-level. Ensure your work is long enough to keep the cable in place, up to a maximum of 15 feet (4.6 meters) (5 meters).
  • You can connect multiple extension cables if needed.
  • Dynamic USB expanders (US 10USD) allow more cable runs, allowing for higher external antenna placement.

#4: Target your dish. 

Find the remote wifi transmitter you want to access.

  • Your wifi antenna is very directional, so achieving the goal is essential. The remote antenna is the most effective place to level the dish, although wandering reflections from buildings, etc., sometimes give right signals from unexpected directions.
  • You can use a cheap hand-held laser pointer to verify that your wireless transmitter is OK. Have numerously enjoyable along with your cat when you’re browsing the net!

#5: Assemble the system. 

Connect the wifi dongle and USB extension cable to the dish with die ties, tape, or hot melt glue.

  • You want to dongle at the height of the dish’s focal point “hotspot” – radio signals come in and bounce toward the centre, just above the surface of the dish.
  • The best dongle location can be found with a simple experiment. One way to do this is to cover the dish with aluminium foil and see if it reflects the sun. 
  • In this case, you will need a small support stick to get the dongle from the dish’s surface.
  • Alternative auxiliary methods use wire tied to the dish’s face like a spider’s web, hollow out plastic garden hose equipment, or even cut sticks!

Key Features of wifi Antenna

Signal Type – 802.11ac is a full 5 GHz and uses beamforming to keep the data stream more direct on the client’s devices. Older wifi antennas and cards may end up at 802.11n, which will not give you the fastest possible data speed.

USB Type – Unless you have an older computer, you should have USB 3.0 ports. It can run at speeds of 5 gigabits per second (or about 640 MB per second). If you’re stuck with USB 2.0, you’re looking for a maximum of 480 megabits per second (or 60 MB per second for data transfer).

Antennas DBI – Antennas fall into DBi, usually for the 2dBi or 5dBi we are looking at. 5dBi antennas are better at taking weak signals (further away) than 2dBi. But 2DBI can maintain strong correlations with strong signals.

Advantages of Laptop Antenna

There are some situations when the laptop wifi antenna booster helps a lot. The first is when I live in a hotel, guest house, or hostel, and the wifi signal does not reach my room.

There may be only one router, and it is in a public area. By connecting my external wifi antenna, I can work from my room’s comfort with powerful signals.

This range takes a few hundred yards, depending on how many walls/buildings there are.

The second situation is when I find the perfect cafe to work in (environment, coffee, prices, food, comfort), but their wifi connection is backed up. However, a restaurant down the street may have a much better relationship.

Using my wifi antenna, I can connect to another cafe’s Fast wifi while working from the restaurant, while I prefer it.

It could not sound like a lot, and however, as a digital gipsy engaged on the road, I need to find an ample workspace with strong wifi for my productivity.

FAQS – How to Make a Wifi Antenna for Laptop

  1. How do laptop wifi antennas work?

    These include slots (for CDs), holes (for keys, screens, cables), seams, etc. Indeed, the electric field transmitted by the antenna is prevented from the case. This electric field causes RF currents in the case, as the charge carriers (electrons) in the metal want to find the lowest possible electrical potential.

  2. How can I make my wifi antenna stronger?

    Try switching your router and devices to the 5GHz frequency band, which has a lot of channels. If your router does not support 5GHz, select another track in the device settings. Microwave ovens also work in the 2.4GHz frequency band.

  3. Do wifi antennas really work?

    Does the antenna receive or transmit? Both of them. Although a wifi signal contains both information sent and received by both parties, it is essential to know that the antenna increases the chances of success of the radio connected to it.

  4. Do antennas help wifi?

    Wifi vendors almost always slap cheap antennas. But you can buy an elongated antenna, usually giving you better range and performance. Replacing the antenna (s) on your router can give you better overall coverage.

  5. What can you use as a WiFi antenna?

    Here's a method approach to building a long-range WiFi antenna for your house. Read on to learn more. For this project, you'll need roughly six tin can tops, as well as several tools and supplies. To support the antenna, you'll need a tiny tripod stand. It's an easy and quick build.
