Various types of antenna
What are the various types of antennas? Describe in brief.
Expert
The antenna (or aerial) is a transducer which transmits or receives the electromagnetic waves. In another words, antennas transform electromagnetic radiation into electric current or vice-versa.
They are mainly used to transmit and receive the electromagnetic radiation of radio frequency, that is, radio waves and are essential part of all the radio equipment. There are various types of antennas, they can mainly sub-divide into directional and unidirectional is a simple kind of directional antennas: helical antenna a simple kind of unidirectional antennas: Yagi and loop antennas.

The network demonstrated in figure presents the input of a biomedical amplifier, now the input impedance is seem purely resistive, R and a capacitor, C, is used to block dc. Q : Make a RLC network that have only two Replace the network demonstrated below, that operates at a frequency of 50Hz, along with an equivalent network containing only two passive elements. Q : Synchronizing inverter using a I need some help with a project that I am doing. I am asked to make an inverter that can synchronise itself with a local power supply. The only information provided by my project supervisor was as follows: 1. Look at a method of cr
