Shunt antenna
WebShunt and notch-fed HF aircraft antennas. Abstract: In the hf range radiation from aircraft must be accomplished by exciting radiating currents on the airframe itself. One method of exciting such currents is by shunts or notches which electrically penetrate the airframe. The strength of coupling of such devices is analyzed and shown to be ... WebSep 21, 2024 · As the switch 804A and the shunt switch 806A are activated and the switch 804B and the shunt switch 806B are deactivated, the isolation/phase-shifting circuitry 58 may couple the processor 12 to the first end 816A of the inductor 812B, which may inductively transfer the transmit signal from the inductor 812B to the inductor 812A …

WebMay 3, 2024 · This is post 2610 in a continuing series of simple ham radio antennas. Many radio amateurs shunt feed their towers as vertical antennas for the lower HF bands (160m-40m). Although the procedure appears clear-cut, there are several factors that must be considered before you convert your tower to a vertical antenna. WebMay 21, 2024 · A strategy for matching is to create an L network being a capacitive reactance in series with the base of the antenna, and a shunt inductance. The capacitive reactance can be obtained by ‘detuning’ (shortening) the whip if it has a suitable adjustment. The chart above from one of my articles provides help in designing a suitable shunt …
WebThe DX Engineering Vertical Antenna Matching Network, DXE-VMN-1, is a custom-designed impedance matching coil that is used at the feedpoint of a low band HF quarter-wave vertical or a Hustler 4-BTV, 5-BTV or 6-BTV multi-band vertical antenna. In most ground-mounted 160, 80, 60 or 40 meter mono-band vertical antenna installations with very good ... WebThe coil will not need further adjustment unless you change the antenna's length, add a cap hat, or perhaps relocate the antenna. The photos show the readout of a screwdriver antenna, on 40 meters, without any matching, and after the shunt coil was installed and adjusted (left and right respectively). Results on 80 meters will be similar.
WebIn this paper, a new approach of substrate integrated waveguide (SIW) based array antenna with wide bandwidth is presented. Each element of this proposed antenna array consists of a shunt slot and a post placed oppositely offset from center line in a SIW. Shunt slots radiate electromagnetic energy in upper hemisphere.
