    Design of a Tri Band 5-Fingers Shaped Microstrip Patch Antenna With an Adjustable Resistor
    (Institute of Electrical and Electronics Engineers Inc., 2014) Aoad, Ashrf; Aydin, Zafer; Korkmaz, Erdal
    This paper presents a tri band 5-fingers shaped microstrip patch antenna, which resonates initially at dual band of 3.2 GHz and 5.2 GHz frequencies for VSWR < 2. The antenna is modified by adding an adjustable resistor between the conductor and the reflecting plane giving a third resonant frequency of 2.4 GHz. A decrease in the return loss at 2.4 GHz is observed by modifying the value of the resistance. Impedance bandwidth and the resonant frequencies are examined with respect to the variability of the parameters of the antenna and the position of the adjustable resistor. The size of the antenna has been reduced by 57.9% in length and 14.06% in width. The proposed antenna can be used for 4G, WLAN, and Wi-MAX. The antenna is designed and optimized by using the commercial CST software. © 2016 Elsevier B.V., All rights reserved.
