Title: Methods used for the antenna design

The week before this material have been chosen for the design of the antenna. The methods that was chosen in designing of the antenna was a stacked Dr and a power divider for the antenna. For the feeding method of this antenna, i used a slot feeding method for the antenna.

Stacked DR

Stacked DRA provides a wider impedance bandwidth with a flexible shape that can be used as compared to a microstrip patch antenna. Once the DR is chosen which consists of a low permittivity the size of the antenna itself will increase and causes the bandwidth to become wider. 

From the above image, the DR is stacked in which the Rogers RO6010 is placed in between FR4.


T-Junction Power Divider

A power divider is also known as a power splitter and this is a passive device that is commonly used in the field of radio technology. Using it in reverse, it can be used as a power combiner. A power divider’s function is to split one input signal into two or more smaller signal.

As from the figure above it shows the classical design of the T-Junction Power divider. In this design, there is no isolation impedance in the design. The design consists of four parts for the transmission line. Due to no isolation impedance in the T-Junction Power Divider, the dissipation power can be ignored and the cost of the design can be reduced rapidly.
