Greetings, is there any specific forum for catching the technical specification of antenna designs. Say (gain, bandwidth, beam width should be this value for antenna designed for this application). Healthy discussion on the same is awaited.
The technical specifications of antenna designs are multifaceted, encompassing various aspects that influence their functionality and performance. Here's a breakdown of some key elements:
Functional Specifications:
- Frequency and Wavelength: Antennas are designed to operate within specific frequency ranges, with a corresponding wavelength. The antenna's size is often related to the wavelength, with quarter-wavelength being an optimal size for efficient operation. https://www.european-antennas.co.uk/products/
- Bandwidth: This refers to the range of frequencies over which the antenna performs effectively. It's typically expressed as a percentage of the center frequency.
Performance Specifications:
- Gain: This parameter indicates how efficiently the antenna concentrates the radiated power in a particular direction, amplifying the signal strength.
- Directivity: Similar to gain, it describes the antenna's ability to focus energy in a specific direction. However, it considers the total radiated power, including the weaker areas, whereas gain focuses only on the strongest direction.
- Radiation Pattern: This is a graphical representation of the antenna's radiation intensity in different directions. It helps visualize the antenna's coverage area and signal strength distribution.
- Polarization: This refers to the orientation of the electric field in the radio wave emitted by the antenna. Common polarizations include horizontal and vertical.
Additional Specifications:
- Return Loss: This parameter measures how much radio frequency power is reflected back from the antenna towards the source, indicating how well the antenna is matched to the transmission line.
- Voltage Standing Wave Ratio (VSWR): It is another measure of impedance matching between the antenna and the transmission line, closely related to return loss.
- Efficiency: This signifies how much of the input power is converted into usable radiated power.
Other factors:
- Mounting Type: This refers to the method of installing the antenna, such as on a wall, embedded in a device, or held magnetically.
- Standards and Bands: Antennas need to comply with specific regulatory standards and operate within designated frequency bands for their intended applications.
It's crucial to remember that these specifications are interrelated and influence each other. Choosing the right antenna design involves carefully considering the desired application, frequency range, performance requirements, and constraints like size and cost.
@mirtadha shukur I too agree, still any specific URL to gather the performance requirements for applications.
Rabin Kanisha Antennas are designed always with respect to its target application. Its design specifications are based on its end objective under the operating situation, ensuring it meets the key goal of signal transfer.
Murtadha Shukur has already given a context to your question. I assume you need to design an antenna and so shall need to list out the application requirements. [For standardised applications, these specs are generally codified in standard documents.]
If your application is non-standard, then identify your performance criteria for the end application which shall guide you towards antenna design specs. Reading an assortment of antenna design examples shall definitely be helpful to understand the approach.
Hope I have not added to the confusion.
Cheers
@shiv praised as stated for standardised applications, these specs are generally codified in standard documents, may I know the webpage for gathering those standard documents at least.
