Electronically Steerable planer Phased Array Antenna
A planar phased-array antenna has been constructed from a 15x15 square grid of z-directed monopoles with a length of 0.475 λ, element spacing of 0.29 λ, average directivity of 20.0 dBi across all scan angles, an average H-plane HPBW of 37 degrees, an average E-plane HPBW of 23 degrees, and an efficiency of 99.6%. Two current distributions are tested: uniform and binomial. The binomial current d...
متن کاملan infinite planar array of rectangular microstrip patch antenna analysis
the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...
15 صفحه اولAn Electronically Tunable Resonator for Noise Control
Many engineering systems create unwanted noise that can be reduced by the careful application of engineering noise controls. When this noise travels down tubes and pipes, a tuned resonator can be used to muffle noise escaping from the tube. The classical examples are automobile exhaust and ventilation system noise. In these cases where a narrow frequency band of noise exists, a traditional engi...
متن کاملAn Electronically Switchable Leaky Wave Antenna
We report an electronically switchable dielectric leaky wave antenna. The main beam angle can be electronically steered using p-i-n diodes. The diodes are used as switches to control the radiation from two sets of gratings with different periods, thereby switching the main beam angle. Beam steering is achieved at a single fixed frequency; no frequency sweeping is necessary. A microwave prototyp...
متن کاملElectronically Tunable Signal Processing Circuit
This paper presents a voltage mode universal filter using two multi-output operational transconductance amplifier (OTA). Proposed multi-input single output universal filter employs two capacitors only and realizes all the standard second order filtering functions from same configuration. Filter parameters namely pole frequency and quality factor can be tuned independently without affecting each...
