Abstract
Microwave antennas are widely utilized in telecommunications, radar systems, satellite
communications, and television broadcasting to transmit programs—such as relaying
an outside broadcast to a main studio—as well as in other applications requiring the transmission
of high-frequency electromagnetic waves over long distances.
Fana Broadcasting Corporation (FBC) currently utilizes microwave links to transmit
public and governmental programs from temporary outside broadcast (OB) studios across
Addis Ababa to its main headquarters studio. However, the city’s complex terrain and the
rapid rise of tall buildings frequently obstruct the line of sight between transmitters and
receivers, leading to an increased occurrence of failures during live television broadcasts.
This thesis addresses the identified challenges by designing and optimizing an EthioTelecom
microwave antenna to function as a repeater for broadcasting. It evaluates the impact of
substituting ITU-R parameters with Localized values, such as rain fading, to enhance
performance.
