Example text

To overcome this, the radials should be joined together at intervals by circular conducting rings. These should be closer together at the upper end of the radials to improve the performance at the higher frequencies. An obvious extension of the antenna in Fig. 17 is to make the upper element also as a number of radials. The resulting biconical dipole has a very flat impedance characteristic if the flare angle between opposing radials is of the order of 90°. This topic will be considered in more detail in Chapter 3 since most of the measured results relate to monopoles.

16£ designed for low-level transonic fighter aircraft. These antennas are characterised by high mechanical strength and very good flutter characteristics unlike some of the straight blades and whip antennas they were designed to replace. Both cover the VHF communication band 100156 MHz with a VSWR better than 2*5:1 referred to 50 ohms. In each the sleeve is the outer of the coaxial line, a tubular inner being used to provide the appropriate Zo for optimum bandwidth. Fig. 17 shows VSWR curves of Fig.

This will be modified slightly if the dipole is fat. It would be possible to calculate the radiation patterns in the £-plane. A number of measured patterns are presented in Jasik [4] and demonstrate that long asymmetrical dipoles are very frequency conscious. For overall lengths up to about one wavelength the patterns will not differ significantly from those of symmetrical antennas. King [6] proposed a mean value theorem for the impedance of an asymmetrical dipole. According to this theorem the impedance Z is approximately \{z\ + £2) where Z\ and Zi are the impedances of two centre-fed dipoles of length 2/j and 2/2 (Fig.
