Which antenna is used in 4G?

4G uses a technology called MIMO, which means ‘Multiple Input Multiple Output’ – this is where your modem uses two separate antennas at once to deliver super fast speeds.

What is dual band patch antenna?

The dual band antenna consists of a rectangular patch which is fed by the coaxial probe feeding technique. The ground plane is loaded with two rectangular strip slots and one elliptical slot to drive the antenna into dual mode and to enhance its bandwidth.

How do I increase the bandwidth of a microstrip patch antenna?

Bandwidth of antenna can be increased by various methods such as by increasing the thickness of substrate with low dielectric constant, by probe feeding, by cutting slot, by cutting notches and by different shapes of antenna.

What is a MIMO antenna?

Introduction to MIMO. MIMO stands for Multiple-In Multiple-Out, referring to the fact that when a packet is transmitted into the channel it transmitted on more than one antenna and when it comes out of the channel it is received on multiple antennas.

What is 5G antenna?

5G will use ‘massive’ MIMO (multiple input, multiple output) antennas that have very large numbers of antenna elements or connections to send and receive more data simultaneously. The benefit to users is that more people can simultaneously connect to the network and maintain high throughput.

How does a dual band TV antenna work?

A dual-band antenna is an antenna that can send and receive radio frequency signals at two distinct frequencies. Depending on their configuration, these antennas are capable of using either of the two frequencies individually or at the same time.

What is the difference between dual band and single band WIFI?

Single-band routers use a 2.4 GHz band and are limited in range and speed compared to dual-band routers, which use both the 2.4 GHz and 5 GHz band. Dual band is mainly a way of getting more bandwidth in your wireless network.

How can I improve my antenna efficiency?

If concern is antenna efficiency then material losses (copper or dielectric losses) are an important factor. You can apply reflecting surfaces, active component, EBG structure or slot matching etc to improve radiation efficiency.

Why do 4G routers have 2 antennas?

To take full advantage of MIMO, (currently used in 4G LTE communications), two antennas must be used. LTE uses polarisation diversity to help distinguish between the two data streams sent from the tower. When outside a MIMO area, most modems can still benefit from the use of dual antennas.

Is there a new microstrip antenna for 5G mobile communication?

In this study, a new microstrip antenna is proposed for 5G mobile communication in IEEE802.11ad standard. Hairpin shaped radiating patch is analyzed on three different substrates; FR4, Rogers R054350B and Arlon AD255C.

What is a micro-strip patch antenna?

A Micro-strip patch antenna consists of a radiating patch on one side of a dielectric substrate which has a ground plane on the other side. Invented by Bob Munson in 1972 (but earlier work by Dechamps goes back to1953).

What is transmission line model microstrip antenna?

Transmission-Line Model Microstrip Patch Antennas Slide 19 The transmission-line model represents the microstrip antenna by two slots, separated by a low-impedance �� transmission line of length L. Looking at a cross section of the antenna (x-y plane), this is effectively a non- homogeneous transmission line.

When was the first micro-strip antenna invented?

Invented by Bob Munson in 1972 (but earlier work by Dechamps goes back to1953). 8. Different Parameters of Micro-strip AntennaOL = Length of the Micro-strip Patch ElementOW = Width of the Micro-strip Patch ElementOt= Thickness of PatchOh = Height of the DielectricSubstrate.
