Transducer is the name given to the device, which converts one form of energy into another. The transmission is achieved by using a transducer. The modulation involves varying the parameters of the carrier wave such as amplitude, frequency or phase. The transmitter represents the part of the system where the information signal or the message signal is modulated over a carrier waveform and then transmitted. The source generates the electronic signals to be sent to the receiver. The basic sub-divisions of the Communication system are the source, the transmitter, the transmission path or channel, the receiver and the destination. A Communication system always involves a spectrum or band of frequencies and so bandwidths forms an important feature to it. The message can originate from any information source irrespective of whether it is speech from an individual or numerical data from a computer. The very word Communication refers to sending, receiving and processing the information by external means.
The principle objective of a communication system is to transmit information signal from one point to another. Therefore, it can be deduced that an antenna acts as a band pass filter and a transducer. Each antenna is designed for a certain frequency beyond which the antenna rejects the signal. Such a current will generate an electromagnetic field around the wire and the field will pulse and vary as electric current does. An antenna will be outlined as any wire or conductor that carries a pulsing or electrical energy.

If exact combination of slot and shape of feed is chosen, it gives an optimum impedance bandwidth with an improved radiation pattern. The aperture coupled patch antenna microstrip feedline, substrates, ground plane slot, and patch dimensions are varied to determine effects on antenna performance which eliminates the electrical connection between the radiating conductors and feed by employing dielectric substrates separated by a ground plane.
