Please show step to answer problem below A half-wave dipole is radiating into free-space. The coordinate...
A lossless, resonant, center-fed half-wavelength (1/2) linear dipole, radiating in free-space is attached to a lossless transmission line whose characteristic impedance is 75 2. This dipole antenna has a radius of 0.03 2. Calculate the reflection coefficient and discuss how to improve the impedance matching.
11.12 The amplitude of the electric field intensity of a half-wave dipole antenna at r 5 km and /6rad is 0.01 V/m in free space. If the operating frequency is 30 MHz, determine its length and the total power that it radiates. Alse, write express 11.12 The amplitude of the electric field intensity of a half-wave dipole antenna at r 5 km and /6rad is 0.01 V/m in free space. If the operating frequency is 30 MHz, determine its length...

Before beginning the design of an apparatus meeting this standard, the designer shall review the discussion on the limitations and accuracy, Section 13, discussions of the energy flows in a hot box, Annex A2, the metering box wall loss flow, Annex A3, and flanking loss, Annex...
summarizr the followung info and write them in your own words and break them into different key points. 6.5 Metering Chamber: 6.5.1 The minimum size of the metering box is governed by the metering area required to obtain a representative test area for the specimen (see 7.2) and for maintenance of reasonable test accuracy. For example, for specimens incorporating air spaces or stud spaces, the metering area shall span an integral number of spaces (see 5.5). The depth of...
