Frequency Reconfigurable Patch Antenna Controlled by PIN Diodes for Ku and K-Bands Applications

Abstract

The main aim of this work is to design a reconfigurable frequency antenna for the sake of evaluating its performances for telecommunication applications in the Ku and k bands. Using the HFSS software, the proposed antenna structure is optimized with etching two rectangular slots having the same size at the radiant element level. The partial ground plane length is limited at the Lg = 2 mm value. To achieve the desired frequency agility, a PIN diode is inserted into the microstrip line feeding the antenna structure. Depending on the states (ON/OFF) of the integrated PIN diode, several operating frequency bands are obtained. When the PIN is in the OFF state, the antenna covers two frequency bands ] GHz. However, in the ON state, the antenna operates in the [15.2 -15.6] GHz band. These results show that the suggested antenna in this work is a powerful candidate for ensuring the frequency reconfigurability in the frequency domain [14.7 -26.7] GHz.

Compact reconfigurable antenna with pattern diversity for K band applications

“…Very less literatures are available for reconfigurable antenna for K band application. A pattern reconfigurable antenna using multiport excitation, 12 frequency reconfigurable antenna for K band application based on SIW, 13 and PIN diode‐controlled 14 reconfigurable antenna for K band application are few of them. Many antennas are available for K band application, like a horn antenna, 15 a patch antenna for Ku band, 16 ultra‐wideband patch antenna, 17 and wideband antenna for k and Ku band 18 .…”
