“…where β is the propagation constant and u i is the unit vector along the propagation direction of the incident wave (3). Considering the modified current distribution (which includes both azimuthal and radial components of the current), one can evaluate the output modal-induced voltage by substituting (12) in (9), subsequently the outcome in (10).…”

Circular current distribution is conventionally used to model current on spiral antennas. However, this model does not include the radial component of the current on the spiral arms. Therefore, it is valid only for the spiral antennas with very small values of the growth rate, where the radial component of the current is negligible. This study proposes a modified current distribution including both radial and azimuthal components of the current, hence, the modified model is not restricted to very small values of the growth rate. Using the modified current distribution, the radiation characteristics of spiral antennas with different growth rates are extracted. Validation is achieved by comparison of the results with those obtained by full wave numerical simulations.

“…N-arm spiral antenna is well known as a wideband and low-profile antenna with circular polarisation [1][2][3][4]. Because of the spiral's wideband features, much attention has been given to this subject on recent literature.…”

“…These results would be improved if the ground plane was bigger, but in a limited environment this is not possible with a metallic reflector. The next step, to obtain a more compact directive antenna is to use a high impedance reflector, that has wideband characteristics [8].…”

In this paper, a directive sinuous slot antenna for Ultra Wideband (UWB) applications is presented. This antenna is feeding by a microstrip taper balun, which can be used as a coaxial line to Lecher line transition. To obtain directive antenna a reflector has been added and optimized. Finally we realized, a compact directive UWB slot sinuous antenna that is included in a 5 cm 3 volume. The balun and the antenna were modeled with CST Microwave studio. The conception of the antenna has been validated by measurements.

“…The computed return loss is showed along with measured values of the Xerox ink & Cabot ink printed antennas in Figure 7 that the proposed antenna has better return loss and is less than −15 dB throughout the frequency band of interest (and in eloquence with [35,36]), which is the paramount requirement of antennas for optimal performance. Furthermore, the stable response of paper substrate at higher frequencies, (although with a certain amount of variations but within acceptable values) make it a suitable candidate for broadband antennas.…”

Abstract-A parametric analysis is performed for a wideband Archimedean spiral antenna in recognition of an emerging concept to integrate RFID along with several applications by using a single antenna. The antenna is fabricated using state-of-the-art inkjet printing technology on various commercially available paper substrates to provide the low-cost, flexible RF modules for the next generation of "green" electronics. The effects on electromagnetic characteristics of the planar Archimedean spiral antenna, due to the use of paper are investigated besides other parameters. The proposed antenna is evaluated and optimized for operational range from 0.8-3.0 GHz. It exhibits exceptional coverage throughout numerous RFID ISM bands so do for other wireless applications.
