Antenna is transducer device. Generally it is called passive

element because without any external equipment. It is not

work as trans meter &receiver.

Generally the converts electric power into radio waves and

vice versa . so we are called is radio trans meter

Or radio receiver.

Generally antenna has various type available in a market

for various purpose. But we have generally in telecom field

we are using panel antenna.

Each group of long array

antennas is connected with

each other.

And provide separate port

for connection.

Made up of by numbers of

long array antennas in the

group

Long Array Antennas

Generally it is used in a 2G

3G and 4G antenna.

Generally the size of antenna port is 7/8 female co-

axial . input impedance is 50E. It’s a global standard of

this antenna.

The image of panel antenna is :-

•

Single band antenna

is a support single frequency band. It’s is a one port

antenna Generally the size of antenna port is7/8 female

co-axial . input impedance is 50E. It’s a global standard

of this antenna.

Such as, GSM 900, GSM 900P, GSM 900E,GSM 1800,

DCS1900 DCS 1900, WCDMA 2100, LTE 2350, CDMA

850, GSM 800

It’s support two

different band or different technology.It’s is a one port antenna Generally the size of antenna port

is7/8 female co-axial . input impedance is 50E. It’s a global

standard of this antenna.

such as… GSM 900 & GSM 1800

It can support three

different band technology.

Such as GSM 900 GSM 900E & GSM 800

It can support four

different band

Technology. Four different technology.

Such as GSM 900 GSM 900P GSM 900E & GSM 1800

The size of single port

antenna is 7/8” female. Generally it’s use in a single

band antenna.

The image of single band antenna is given below :-

single port panel antenna

In which both the

antenna is a 7/8 inch female in the two antenna but

connected to each other. Impedance of antenna is

50E.

Image of dual port antenna is given below

dual port antenna

Quart port antenna have

four port but these are divide two group. It’s size7/8 inch

female so it’s call a dual ,dual port antenna.

It’s a dual band antenna. Each port is a different

frequency band.

The image of quad port antenna is given below.

QUAD PORT ANTENNA

it is a triple dual band

antenna. And the size of

each and every port is

same as single port

antenna. The image of

hexa port antenna is given

below :-

Generally its quad

dual port antenna . means two quad port antenna both

connect in. size and shape of this antenna is same as

one port antenna

mostly used in IBS

Site & underground Metro. Station. 360 ⁰ radiation

pattern

Used for highway coverage

It radiates in single direction

only.

Most commonly used.

65⁰ beam width used.

Tilt is a arrangement of antenna as upward and

downward . means we can arrange the antenna as par as

requirement to limited angle . it’s a three type such as

mechanical tilt. Electrical tilt. Remote electrical tilt.

It is a mechanical arrangement in antenna

which provides upward & downward

Only downward tilt is possible.

It is done by the reducing of power strength.

This power strength is controlled by a knob

This type of tilt give by the

computer or laptop from the shelter .be cause the antenna

is directly connected to BTS so we can give the command

and give the tilt
