Printed ultra-wideband monopole U-slotted antenna for triple band-rejection

Design of a Compact CPW-Fed Monopole Antenna With Asymmetrical Hexagonal Slot Loaded Ground Structure for C/X/Ku Band Applications

“…Hence, the compact size antenna can easily be imbedded in small devices and MMICs for modern applications. However, the impedance bandwidth (4.86 to 13.66) / 8.8 GHz of the proposed antenna is greater than the impedance bandwidth of the antennas reported in [16], [17], [19], [20] by 800 MHz, 750 MHz, 1800 MHz and 390 MHz, respectively, and lesser than that of the antenna reported in [18] by 200 MHz.…”

“…The comparative study is carried out in terms of the size of antenna structure, substrate material, impedance bandwidth and peak gain of the antenna. From perusal of Table I, it is observed that the patch area (396 mm 2 ) of the proposed antenna is smaller than the antennas reported in [16]- [20] by a factor of 2.12, 1.51, 1.57, 6.06 and 3.17, respectively. Hence, the compact size antenna can easily be imbedded in small devices and MMICs for modern applications.…”

“…From the comparative overview of the peak gain (dBi) between the proposed antenna and reported antennas, it can be observed that peak gain of the proposed patch antenna is greater than that of antennas reported in [17], [20], equal to that of the antenna in [19] and marginally smaller than that of the antennas reported in [16], [18].…”
