Multi-band Frequency Reconfigurable Planar Bow-tie Antenna

EasyChair Preprint no. 2803

6 pagesDate: February 28, 2020


A multi-band frequency reconfigurable planar bow-tie antenna is designed and simulated in this paper. Firstly, a self-complementary bow-tie antenna is designed and implemented; this antenna is characterized by a simple feeding. It is directly matched to the SMA connector via 50Ω micro-strip feed line. Second, a rectangular slot and a PIN diode are added to adjust electronically the bow-tie antenna over (1.7-6GHz) frequency band. The proposed antenna shows two different states by switch the PIN diode. In ON state, the antenna covers DCS, Bluetooth and Wlan bands and in OFF state the antenna covers the wide-band (2-4.9GHz) and Wlan band. Moreover, hexagonic parasitic elements are integrated in the bottom and in the top side of the substrate to cover (1.49-1.7GHz) and (1.77-1.85GHz) bands. By switching PIN diode, multi-band frequencies’ are shown in the ON and the OFF states with a gain varied between 0.5 and 3.5dB.
