چکیده
In this study, a novel antenna design is proposed for designing frequency-reconfigurable wide-angle beam scanning and applied to squarely modulated reactance surface leaky wave antenna. The angle electronically steered with discretely (rough scan) continuously (precise by controlling the antenna’s modulation period at any fixed frequency, respectively. procedure provided using unit cell composed of parallel microstrip conductors varactors in between. controlled DC bias voltages varactors. Based on dispersion characteristic antenna, states different frequencies are designed. Although operation frequency can be arbitrary, model designed two 4.6 5.8 GHz. It was implemented, experimented demonstration method. shown an EM simulation that 72° 91° possible GHz bands, Also, some operational (beams) experimentally verified through utilizing switching circuit. numerical result experimental showed good agreement which verifies scheme.

Reactance of a Sinusoidally Driven Antenna
This problem is based on the overoptimistic claim in [1] that the reactance of an antenna can be decomposed into capacitive and inductive reactances. Deduction of antenna reactance via so-called complex Poynting theorem (sec. 13.14 of [2], sec. 2.20 of [3]) goes back at least to sec. 5 of [4]. See also chap. 8 of [5]. We consider only media with unit relative permittivity and permeability. For ...
متن کاملDiversity Antenna Loaded with Reactance Control Circuits Configured with Variable Capacitors for Effective Combining
Diversity antenna loaded with the reactance control circuits configured with variable capacitors was proposed. Advantages of this proposed configuration are that signals are detected only by one receiver and that the hardware architecture is simple. However, effective combining has not been achieved due to a mismatch between the combiner and the receiver. In order to improve this problem, we co...

Electronic control of microwave antennas and circuits is usually based on the use of reverse biased semiconductor junctions. Optical control of such circuits has been by directly illuminating the active (depletion) regions of the semiconductor junctions. In this paper we report indirect optical control of microwave antennas and circuits using a photovoltaic array that generates a light dependen...
متن کاملReactance, Compliance, and Anticipated Regret
The current work explored the relations among reactance, regret, and behavioral choice. A possible mechanism for reactance in opposition to persuasion attempts involves people anticipating greater regret for negative outcomes after complying with an agent of persuasion than for negative outcomes after reacting against an agent of persuasion. Some participants were asked to anticipate regret pri...
متن کاملReactance of Small Antennas
The voltage difference between the two arms of the antenna is On the right is Fig. 86 from [2]. In general the electric field is related to the scalar and vector potentials by E = −∇V − ∂A/∂t = −∇V + iωA, assuming a time dependence of the form e−iωt. Then, ∫ 2 1 E · dl = V1 − V2 + iω ∫ 2 1 A · dl. However, close to a small linear dipole antenna the electric field is much larger than the magneti...
