Answers.com is the place to go to get the answers you need and to ask the questions you want What is the advantage of using a helical antenna over a ... Helical antennas can be made to operate one of two ways, normal-mode helical and axial-mode helical, which both have specific advantages over a straight monopole antenna. Normal-mode helical: The antenna is the same length as the monopole, still produces as omnidirectional radiation pattern, and is linearly polarized. Slot Antenna Slot antennas are used typically at frequencies between 300 MHz and 24 GHz. The slot antenna is popular because they can be cut out of whatever surface they are to be mounted on, and have radiation patterns that are roughly omnidirectional (similar to a linear wire antenna, as we'll see). The polarization of the slot antenna is linear.
Impedance of Slot Antennas 5.1 Introduction The characterization an antenna requires knowledge of the input impedance looking into the antenna from the detector. This includes the associated feed network used to connect the detector or receiver circuit to the antenna. In this chapter we
