The long-wire dipole antenna is effective for low-frequency systems. Adding LC traps makes a single-band dipole antenna into ...

Horizontal wires, vertical ... FM antennas on top of their AM radiators and avoid the expense of additional towers. Many original FM antennas were designed as top-mounted radiators, which should ...

3). The ground plane antenna is just a half of a dipole, with the other element of the dipole represented by the ground plane. The polarization is vertical, and the radiation pattern is circular ...

The horizontal radiation pattern of the dipole is a figure 8 (Fig. 3). Maximum signal occurs broadside to the antenna. Figure 4 shows the vertical radiation pattern. They are ideal patterns that ...

It’s a sleeve dipole, think of it as a vertical dipole antenna in which the lower radiator is hollow, and through which the feeder is routed. These antennas do a reasonable job of covering a ...

Dipole Antenna with Views of the Corresponding Radiation Pattern. The gains we have been quoting so far ... Circularly polarized radiation can be regarded as the sum of vertical and horizontal ...
