A Pattern AND Polarization Reconfigurable Liquid Metal Helical Antenna
This paper discusses the use of pin diodes to modify the radiation pattern of an annular slot antenna (ASA) keeping constant the frequency of operation. The planar antenna is fabricated on the top side of a Duroid substrate and the microstrip feeding line with the matching network is fabricated on the back side of the board. Planar square multiband frequency reconfigurable microstrip ... For example, a frequency reconfigurable planar inverted-F antenna was designed in , using two PIN diodes, three reconfigurable operating bands (2.3–2.4, 2.5–2.7, and 3.4–3.6 GHz) are achieved. In  , a printed Yagi-Uda antenna was proposed; where frequency agility is obtained by loading the driver dipole arms and four directors with ...

The annular slot antenna consists of a circular slot on a square, metal ground plane that is fed by a microstrip line, designed on the bottom of theIn this project, we present for first time an annular slot antenna with simultaneous frequency and radiation pattern reconfigurability, by using pin diodes to... [Moved]: Pattern and Frequency Reconfigurable Annular … Hi normally we use PIN diodes for pattern reconfigurable antenna. My question is that as the current in antenna is ac how does the PIN diode works.When a PIN diode is forward biased it behaves, in AC, like a variable resistor. The value of its resistance depends from the DC current flowing into the...
One-shot three-dimensional measurements with a fiber bundle using a chirped optical frequency comb
Design of reconfigurable antennas based on an L-shaped slot ... A basic antenna structure to design pattern and pattern/frequency reconfigurable antennas is proposed. The structure consists of an L-shaped slot, PIN diodes, lumped capacitors and bias networks. The PIN diodes and the lumped capacitors located at specific positions are used to create short circuits across the slot.
