Multiband folded dipole antenna

The original ZS6BKW article does mention that installed in an inverted-V configuration, resonances would be a little low. After reducing the length of the ladder line to the design figure of 12.2m and tweaking the length of the wires, ending up at 13.5m, the antenna now resonates beautifully on 7.1, 14.11, 18.06 and 24.8 MHz.

102 ft multi-band dipole antenna. It covers 10-160 bands with a tuner. Requires a coaxial cable feeder. Compact and powerful design. Can be installed within 31 meters of space.

The sleeve dipole works through capacitive coupling of the antenna elements. The signal is generated from the dipole. The signal is radiated to and from the resonant antenna, whether it is the sleeve or the dipole. The sleeves and the dipole do not necessarily need to be the same materials or size of wire. One use of different wires could be to.

Dipole Antennas: 850-950MHz. Dipole Antennas of the 850-950MHz frequency band are omnidirectional antennas used for the Global System for Mobile Communication (GSM), CDMA, and ISM applications including LoRa. The dipole antenna mates with the wireless access points that have a female connector and operate in the 900MHz.

A multiband printed dipole antenna for wireless local area network (WLAN) and long-term evolution-advanced (LTE-A) applications is investigated here. Its multiband characteristic is enabled by the Y-slot present in the upper arm of the dipole, while the antenna's dimensions are at the lowest operating frequency. It features bandwidth of 14.6%.

The Folded Dipole Antenna A folded dipole is a dipole antenna with the ends folded back around and connected to each other, forming a loop as shown in Figure 1. Figure 1. A Folded Dipole Antenna of length L. Typically, the width d of the folded dipole antenna is much smaller than the length L.

A multiband printed dipole antenna for wireless local area network (WLAN) and long-term evolution-advanced (LTE-A) applications is investigated here. Its multiband characteristic is enabled by the Y-slot present in the upper arm of the dipole, while the antenna's dimensions are at the lowest operating frequency. It features bandwidth of 14.6%.

A folded dipole or resonant loop antenna is, electrically, a full wavelength from one side of the feed point to the other. If the loop were straightened out, you'd see a standing wave with voltage nodes at each end and the middle, and current nodes at 1/4 and 3/4 of the length.

In this paper, characteristics of a built-in balanced folded slotted dipole antenna with a novel dual-arm structure for mobile handsets are introduced and analysed in order to realise multiple- band operation, including GSM1800, GSM1900, UMTS and WLAN (2.4 GHz).

These are half-wave dipole antennas, multiple half-wave dipole antennas, folded dipole antennas, non-resonant dipole, and short dipole. Among the 5 dipole antennas listed, the most popular dipole antenna used in radio receivers is the half-wave dipole. The name "half-wave dipole" was coined from its length.

to obtain a tri-band antenna with dipole modes, we use the principle of the open-sleeve antenna on an antenna that radiates naturally two dipole modes by changing the quadrupole mode into a dipole mode with parasitic elements. The main element of our antenna is a folded U-shaped antenna that radiates two dipole modes.
