A receiver is any electronic device that receives an external signal (e.g., radio, electrical or optical) and converts the information carried by them to a usable internal form.

Received power from multiple transmitters
Now then, the fields at the receiver due to both antennas is \$ E_{RX} = E_{TX1}+E_{TX2} = E_{TX}\dfrac{e^{-jkr_1}}{4\pi |r_1|}+E_{TX}\dfrac{e^{-jkr_2}}{4\pi |r_2|} \$
Since in the given situation \$r_ … 1 = r_2 \$ then the equation is simplified as
\$ E_{RX} = 2 E_{TX}\dfrac{e^{-jkr_1}}{4\pi |r_1|} \$
This is to say that the received fields at the receiver are double what they would have been for one …
