AR RF/Microwave Instrumentation, a developer of broadband high power, solid state RF amplifiers and microwave amplifiers, has announced the “Cavitenna” RF antenna, a top-loaded monopole antenna that “[utilizes] the shielded room as a reverberating antenna, and the wall as the antenna’s ground plane. As a result, it accommodates extremely high power and corresponding field intensities, comparable to those of log-periodic antennas four times the size of the Cavitenna.”
According to AR, “the advantages of the Cavitenna are more apparent when used in fully automated test configurations. . . . It can be mounted on a wall and not protrude into the test volume like other antennas. [In addition,] the Cavitenna’s compact design and high efficiency can even allow some reverberation chambers to extend their usefulness to lower frequencies.”
