dz ふ z cos θ Figure 2: Far-field radiation for half-wavelength dipole. Part 1: Design of 2.4 GHz dipole antenna You are tasked with developing an antenna for a Radar that operates in the ISM (Instrument, Scientific, Medical) band. The band of frequency is defined from 2.4 GHz to 2.5 GHz. Now that you have walked through the steps to generate the electromagnetic fields and the average power density, you can use this information to characterize and complete the design...

A microwave oven operates at 2.30 GHz . What is the wavelength of the radiation produced by this appliance? Express the wavelength numerically in nanometers.
Find the frequency in terahertz of visible light with a wavelength of 559 nm in vacuum. What is the wavelength in centimeters of electromagnetic microwave radiation whose frequency is 8.91 GHz?
The frequency and wavelength of EM waves can vary over a wide range of values. Scientists refer to the full range of frequencies that EM radiation can have as the electromagnetic spectrum. Electromagnetic waves are used extensively in modern technology. Many devices are built to emit and/or receive EM waves at a very specific frequency, or within a narrow band of frequencies. Here are some examples followed by their frequencies of operation: • garage door openers: 40.0 MHz, • standard cordless phones: 40.0...
