Uniform Aperture Circular Antenna
Uniformly illuminated circular aperture antenna.
This antenna uses a polar coordinate system.
Parameter | Description |
---|---|
Beamwidth | The beamwidth of the antenna gain pattern. Valid if Use Beamwidth is selected. The diameter and gain are automatically calculated on the basis of this value and the frequency. |
Diameter | Diameter of the dish. Valid if Use Diameter is selected. The beamwidth and gain are automatically calculated on the basis of this value and the frequency. |
Design Frequency |
This is the frequency of the antenna. The antenna design frequency is independent of the operational frequency of a transmitter, receiver, or radar. Changing the frequency of a transmitter, receiver, or radar does not update an embedded antenna's design frequency, nor vice versa. The design frequency is solely used at antenna configuration time to compute the antenna size from its max gain or beamwidth settings. A mismatch between signal frequency and antenna design frequency typically causes performance degradation. |
Main-lobe Gain | The main-lobe gain value. Valid if Computed is not selected. Select Computed to automatically calculate the main-lobe gain based on beamwidth or diameter, efficiency, and design frequency. |
Efficiency | Specify the antenna efficiency factor, ranging from 0 to 100 percent. |
Back-lobe Gain |
You can use back-lobe gain two different ways:
