Dipole antennas
Much of the work of Spectrum Planning Group is based on well established principles of ‘antennas and propagation’. Propagation matters have received a lot of attention over the years and much has been written on the topic but the ‘antennas’ part, although arguably simpler, may lack a suitable written reference that gathers much of the relevant material into one place. The primary purpose of thi...
متن کاملThe Design of W - Periodic Dipole Antennas
A mathemat ica l ana lys i s of the logar i thmica l ly per iodic d ipole class of frequency independent antennas, which takes into account the mutual coupling between dipole elements, is descr ibed. A h igh speed d ig i t a l computer (ILLIAC) is used t o c a l c u l a t e t h e i n p u t impedance gain, and bandwidth, a s w e l l a s t h e i n p u t c u r r e n t and vol tage of the several...
متن کاملPolarization sensitivity of optical resonant dipole antennas
The polarization sensitivity of optical resonant dipole antennas is investigated numerically using the Green’s tensor technique. The electric field-intensity in the feed-gap of the antenna is calculated as function of the polarization of the incident field. A simple analytical model is proposed that matches the numerical data very well. While a very strong polarization sensitivity can be achiev...
متن کاملThe Quasi-Near Fields of Dipole Antennas
The electricand magnetic-field components produced by vertical and horizontal dipole antenuas (both electric and magnetic types) located over, on, or below the surface of a semi -Mte conducting medium are derived and presented for the quasi-near range. (The measurement distance is much greater than an earth skin depth, but much less than a free-space wavelength.) Previously derived results are ...
متن کاملThe Design of Calculable Standard Dipole Antennas in the Frequency Range of 1 - 3 GHz
This paper presents the design of a calculable standard dipole antenna with a hybrid balun in the frequency range of 1 GHz to 3 GHz. A new formula of an antenna factor is derived by using the power mismatch-loss concept. The antenna factors derived in this paper are in good agreement with the results calculated from S-parameters. The design results show that the calculable dipole antenna with a...
