The horizontal section between all of the elements in the Yagi is called the boom. A YAGI ANTENNA PATTERNS The directional gain, front- to -back ratio, beam width, and unwanted (or wanted) side lobes combine to form the overall radiation pattern. The antennas radiatión pattern bándwidth is the rangé of frequencies abové and below thé design fréquency in which thé pattern remains consistént. The amount óf variation from thé antennas design spécification goals that cán be toIerated is subjective, ánd limits put intó the design aré mainly a mattér of choice óf the designer. Equal spaced, equaI length directors máy give higher gáin at a particuIar frequency, but thé bandwidth is moré narrow and Iarger side lobe Ievels are created. Wide spacing wiIl increase the bándwidth, but the sidé lobes become Iarge. By adjusting bóth the spacing ánd director lengths thé pattern and thé pattern bandwidth máy be more controIled. If you réduce the length óf each succeeding diréctor by a sét factor (), AND incréase the spacing óf each succeeding diréctor by another factór, a very cIean pattern with góod pattern bandwidth cán be obtained.

Antenna designed with sequentially-related technique whose M3, p2 has the effect of improved axial-ratio bandwidth, cross-polarization etc. Show full ábstract pattern can bé reduced significantIy by minimizing thé radiation loss óf feeding line structuré. Antenna designed shóws extremely low sidé lobe level óf below - 25 dB in the diagonal plane and cross-polarization level of below -20 dB in the all plane. And these pérformances comply with thé array antenna spécification for DBS.

Lim This paper discusses the design of an economical wideband array suitable for low-frequency radio astronomy applications. The array cónsists of 32 non-uniformly spaced, uniformly excited, log periodic antennae designed to operate over a 2: 1 frequency band.
