Antenna design software is used for the design and electromagnetic analysis of all types of antenna systems, including planar and microstrip antennas, hollow waveguide and horn antennas, and helical antennas. Some applications for antenna design software include telecommunications and commercial satellites, military communication systems, and consumer products such as cars, radios, and television (TVs). Antenna designers use antenna software to perform complex calculations and post-processing routines such as near field plots, stop-and-reverse (SAR) calculations, and phase center analysis. Antenna design software is also used to determine directivity or far field gain for both single antennas and antenna arrays in polar, X-Y, and three-dimensional (3D) plots. Windows (Microsoft), Linux (Linus Torvalds), UNIX (The Open Group), and Macintosh (Apple Computer) antenna design software is available.
Antenna design software may be used in the electromagnetic simulation (EM simulation) of anechoic chambers and the 3D analysis of nano antennas. Antenna software applications are also used to simulate mobile phone antenna performance at multiple points in the cell phone design change. With consumer products, antenna designers must consider the potential health effects of human exposure to electromagnetic radiation. For example, antenna design software is used to simulate human exposure to electromagnetic fields inside automobiles. Antenna designers may consider the effects on the human body in general, or just on the heads and hands of cell phone users. Other applications for antenna design software include the modeling of miniature antennas that will not degrade in performance when placed near the human body. On-glass antenna simulation is used in automotive applications, both for human health and antenna performance.
Antenna design software is used with wide-angle scattering analysis, the advanced modeling and measurement of wideband horn antennas, and for the design of squint-less horn antennas with a large number of arms or radiating elements. Various software applications for the Windows, Linux, UNIX and Macintosh operating systems (OS) are used to simulate body coil substitutes in the radio frequency (RF), ultra high frequency (UHF) and microwave frequency ranges. Small wideband antennas may require optimization for loss and radiation pattern performance. Antenna design software is also used to design and optimize 2.4-GHz RF module antennas, and to analyze the performance of radio frequency identification (RFID) reader coils and transponders operating at various MHz frequencies.
