Added on - Mar 2020

41092- In this document, we will discuss some important questions related to CDMA and FDMA, and Antenna: an antenna or aerial is the interface between radio waves propagating through space and electric currents moving in metal conductors, used with a transmitter or receiver. Tyes of antenna- Yagi antennas, Horn antennas, Cellular antennas. CDMA (Code division multiple access), FDMA (Frequency division multiple access).

ASSIGNMENT2Question oneTypes of antennaAntenna performs the same functionality regardless of the type or mode of operation. Inessence, they transform electric power into electromagnetic waves (and vice versa) that areferried in free space. However, based on their operation design and structure they do exist indifferent modes[ CITATION Rec111 \l 2057 ].Three major types of antennas exist; directional antennas such as Yagi antenna that propagatesignals in one direction, semi-directional antennas that are restricted in certain directions andOmni-directional antennas (e.g. cellular antennas) that propagate signals in any direction.Yagi antennas:these antennas are designed to have a high gain ratio that results in highlevels of directivity. They are therefore used to focus radio signals in specific directions,moreover, they have good signal to noise ratiosStrengths:1. Their design structure enables them to have a high gain.2. This design and gain also result in good directivity.3. They are simple to design and install[ CITATION rad171 \l 2057 ].Weaknesses1. They have a limited gain ratio, 20dB.2. Secondly, they tend to be long if they are needed for high gain functionalities.Horn antennas (directional antennas)– similar to Yagi antenna, however, these antennasare designed with a hollow structure whose aperture increase towards the exit plane. Thisaperture forms a flare-like section that focuses signals in the desired direction. This design

In conclusion in this document, we will get to know about antennae and different types of antennas and their Strengths and Weaknesses. CDMA (Code division multiple access), FDMA(Frequencydivision multiple access).
