The coupling between the body and the antenna, and the reduction of antenna efficiency, lead to a distortion of the radiation pattern, which depends on the distance as well as on the location on the body. A patch antenna operating at 2.45 GHz, on the head, chest, arm, and leg was ...

As someone else has pointed out, 29.9792 MHz is not a wavelength of 100 mm. I'm not going to work out the wavelength, but it will be very close to 10 m. If the wavelength is 10 m, and your dipole is 100 mm long, then it is very short, and it's radiation pattern would be c...
In general, the aperture angle of the scattering pattern can be approximated by (5.39)θs≈λLs, where Ls is the length of the segment, in the following facet. The former equation is analogous to that of the aperture of an antenna, and the backscattering patterns reminds one of antenna ...

Aperture antennas are microwave transceivers fashioned into disks, dishes, and rectangular arrays, as seen on cell phone towers. The antenna radiation pattern appears as a torus or horn around the beam axis. Others can include helical, conical, parabolic and more; dozens of other antenna types an...
antenna theory/ B5260 Antenna theoryA modified theory is presented to explain the radiation pattern of a system of antennas consisting of a primary aperture like a horn or an open-ended waveguide and two secondary radiators excited by the primary. An earlier assumption made by Butson and ...
In this communication, the design procedure of a wideband antenna with omnidirectional radiation pattern is demonstrated based on the theory of characteristic modes. Consisting of a dipole and a loop antenna, the antenna has a very simple structure. A wide impedance bandwidth is obtained because of...
