Wide-type broadcasting antennas overcoming chu-harrington-fano

Belyansky V.B., Pronina E.D.

In MTUCI, wide-range antennas with distributed mismatch are proposed, the dimensions of which can be smaller than the dimensions of the antennas possessing the lowest possible Q-Harrington quality and Fano-compatible. Such antennas can be made on the basis of log-periodic or quasi-periodic antennas (LPA) using the frequency-dependent insulators (FDI) of the 1st and 2nd types proposed here. 

When using antenna type 1 type antenna, it is proposed to call such an antenna an antenna of the 1st type. Antennas of the 2nd type are suggested to be called antennas using the second type of FDI. The first type of frequency protection is band-pass frequency-dependent insulators, and the second type of protection is insulators transparent at low frequencies. The application of the FDI eliminates the "spreading" of the current cutoff effect when the size of the log-periodic antenna decreases. In antennas of the first type at any frequency within the operating frequency range, only one vibrator is resonant and the quality of its matching with the distributive feeder is determined only by the choice of the value of the lumped matching element and the degree of proximity of the geometric parameter τ to unity, which in principle guarantees the realization. An arbitrarily small antenna with an arbitrarily wide band of frequencies. In antennas of the second type, the active region may include several interconnected blowing elements, which can increase the compactness of the device, but at the same time, the adjustment of the antenna system and its stability becomes much more complicated. Since the publication purpose is to illustrate the possibility of creating ultra-miniature wide-band antennas, at this stage the characteristics of the most characteristic antennas with such properties as type 1 antennas are considered. The frequency characteristics of the FDI, the equivalent LPA scheme with FDI and the dependence of the geometric parameters of the antenna on the normalized length of the LPA arm are given. Also, the dependence of the SWR of the 1st type LPA on the ideal FDI given, and the SWR dependence on the steepness of the slopes of idealized FDI is estimated.
