Microstrip antenna

An antenna serves as the “communicator” between the RF front-end circuitry and the radiation and propagation of electromagnetic waves in free space. In microwave and other wireless applications, an antenna plays a very efficient job. Planar oriented antennas, such as microstrip patch and printed dipole have attracted significant attention of the community of antenna engineers …

Klystron Amplifier

Microwave Tube

Klystron Amplifier To remove the limitation of traditional tubes, microwave tubes are constructed. Microwave tubes take a large transit time for the required operation. The basic principle of operation of the microwave tubes involves a transfer of power from a source of DC voltage to a source of AC voltage by means of a current …

Log Periodic Antenna

Image of LPA, LPA,

Log Periodic Antenna (LPA) is an antenna array of the same type of dipole elements but the length of these elements increases with a common ratio. All these elements which are placed in the antenna are electrically connected. All elements are excited by a common input with the same phase. The structural geometry of LPA …
