WIDEBAND DOUBLE-DIPOLE YAGI-UDA ANTENNA FED BY A ... re°ector, which cannot be well optimized for a radiation pattern like a conventional Yagi-Uda antenna. Recently, CPS-fed planar Yagi-Uda antennas [21,22] have been introduced in the absence of a large ground plane, but these antennas are not suitable for array applications because of their feed structure. Improvement in Radiation Pattern Of Yagi-Uda Antenna Improvement In Radiation Pattern… 28 Figure 3.3 Element Yagi (Reflector+Driven Element+Director) The reflector and directors in the Yagi-Uda antenna are so coupled into parasitic mode; they mutually alter the radiation parameters of the driven element and for each element of the array. Then the physical Lecture Notes - Antennas Radiation Pattern is a function of coordinates given at constant radius in 2D or 3D forms. Reciprocal antennas have identical radiation patterns as transmitter & receiver antennas. Isotropic: A hypothetical, lossless antenna has equal radiation in all direction. Not realized, but used as a reference. Slot antenna - Wikipedia

Radiation of Two Dipole Antennas The simplest form of an antenna array are two short dipole antennas . In this problem you will learn how a phase difference between the currents of both antennas affects their combined radiation pattern .
Multiple half waves dipole antenna: Although the half wave dipole antenna is the most popular, it is possible to use a dipole antenna or aerial that is an odd multiple of half wavelengths long. The radiation pattern is very different, but it still operates effectively in this mode.

Dipole antenna - Wikipedia In radio and telecommunications a dipole antenna or doublet is the simplest and most widely used class of antenna. The dipole is any one of a class of antennas producing a radiation pattern approximating that of an elementary electric dipole with a radiating structure supporting a line current so energized that the current has only one node at each end.
