A compact monopole antenna with frequency reconfiguration is presented in this paper.
The antenna is fed with micro strip line feeding. The antenna dimension is 37x25.5x0.8mm3 and is fabricated on FR4 epoxy substrate. The proposed antenna is a triple band antenna; it covers LTE, Wimax and WLAN applications.
The antenna attains frequency reconfiguration and the aerial is made to be reconfigurable using PIN diodes. The proposed structure is simulated by using HFSS software.
The antenna is operated in 3 bands when 2 diodes D1, D2 are OFF & ON with centre frequencies 2.29GHz, 3.29GHz, 5.19GHz. Efficiency attained by the antenna is 96.3% and gain achieved is 4.7dB. Results: The proposed antenna exhibits good performance and it is well suitable for wireless medical and other communication applications.
