A PIN diode is inserted over the L-shaped para-stubs, meandering of ground plane and so on [3–5]. For sitic element and the rectangular patch, another one is example, UWB slot antennas with reconfigurable band- placed between the two … Cognitive Radio, Reconfigurable Antennas, and Radiobots To obtain the required reconfigurability in the antenna operating frequency, some kind of electrical switching components such as RF-MEMS, PIN diodes, varactors or optical switching components such as Silicon (Si) or Gallium Arsenide (GaAs … World Journal of Research and Review (WJRR) Layer 2 is the multi-path propagation [6, 7]. Generally, a patch antenna, functional microstrip circuit module which includes a single-feed or dual-feed, can generate circular polarized feed-line, two branches of microstrip lines, two PIN … Hlavni dokument_zlatnicek V práci budou řešeny úpravy tvaru pahýlu pro zapojení PIN diod. Funkčnost navržené antény bude ověřena modelováním v programu Ansoft Designer.
The antenna resulted in an omnidirectional radiation pattern which is an essential requirement for the wireless applications. In our proposed design, the two Antennas are isolated with the help of an annular slot. Four PIN diodes were employed for connecting the inner antenna with the outer one by using RLC equivalent of PIN diodes.

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 [2] , a printed Yagi-Uda antenna was proposed; where frequency agility is obtained by loading the driver dipole arms and four directors with ...
