What is the difference between a round antenna rather than one with straight lines?
An antenna works by converting electromagnetic waves, also known as radio waves, into electrical signals. The antenna is designed to resonate at a specific frequency, which allows it to pick up the desired signals and ignore others.
The size and shape of an antenna determine its resonant frequency. This means that different antennas are designed to pick up different frequencies. The size and shape also affect the antenna's directionality and gain, which determine how well it can send and receive signals.
When an electrical current is applied to an antenna, it creates an electromagnetic field around it. This field propagates outward as electromagnetic waves, carrying the electrical signals with it. These waves can then be received by other devices with antennas tuned to the same frequency.
Some antennas, such as dipole antennas, can be designed to work for multiple frequencies. However, they may not perform as well as an antenna specifically designed for a single frequency. Other types of antennas, such as Yagi antennas, are designed for a narrow range of frequencies and may require multiple antennas for different frequencies.
The placement of an antenna can greatly affect its performance. Antennas should be placed in areas with minimal obstructions, such as buildings or trees, to allow for maximum signal strength. The height and orientation of the antenna can also impact its performance, as well as the surrounding terrain and other environmental factors.
