Pattern and frequency reconfigurable annular slot antenna using 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.
The reconfigurable ASA proposed in this paper operates at three frequencies with a central frequency at 5.8 GHz, and it also Index Terms—Annular slot antenna (ASA), frequency reconfig- has a reconfigurable radiation pattern that can position a null urability, pin diode, reconfigurable antenna, reconfigurable radia- tion pattern, slot antenna. Pattern and frequency reconfigurable annular slot antenna ... This paper presents the use of pin diodes to reconfigure the impedance match and modify the radiation pattern of an annular slot antenna (ASA). The planar antenna is fabricated on one side of a Duroid substrate and the microstrip feeding line with the matching network is fabricated on the opposite side of the board. The central frequency is 5.8 GHz and, by reconfiguring the matching circuit ... NAVER Academic > Pattern and frequency reconfigurable ...

Hlavni dokument_zlatnicek V práci budou řešeny úpravy tvaru pahýlu pro zapojení PIN diod. Funkčnost navržené antény bude ověřena modelováním v programu Ansoft Designer.
In this paper, a compact frequency reconfigurable circular patch antenna with an arc-shaped slot loaded in the ground layer is proposed for multiband wireless communication applications. By controlling the ON/OFF states of the five PIN diodes mounted on the arc-shaped slot, the effective length of the arc-shaped slot and the effective length of antennas current are changed, and accordingly six ...
