RANCANG BANGUN ANTENA MONOPOL TRIPLE-BAND ACS-FED RINGKAS UNTUK PERANGKAT IOT PADA JARINGAN WLAN/WIMAX/5G/V2X
This research focuses on investigating a compact ACS-fed monopole antenna
designed to generate three frequency bands in wireless communication
applications. The antenna design combines the ACS-fed technique with C-shaped,
inverted L and U-shaped radiating strip branches so as to downsize the antenna
size and generate multiband radiation. The antenna is implemented on an
inexpensive FR-4 substrate measuring 9×20×1,6 mm3. A systematic parametric
assessment that includes variations in the length and width of the radiating strip
has been carefully carried out, leading to the identification of three optimal
frequency operational modes for the proposed antenna using an EM simulator
Ansoft HFSS. The impedance bandwidths of the lower, middle, and higher
frequency modes are 320 MHz (2,31-2,63 GHz), 470 MHz (3,3-3,77 GHz), and
2820 MHz (5,12-7,94 GHz), respectively. At resonant frequencies of 2,5 GHz, 3,55
GHz, and 5,45 GHz, the measured antenna gain parameters are 5,67 dBi, 5,21
dBi, and 4,56 dBi. Due to its compact form factor and stable characteristics, the
proposed antenna design emerges as a promising solution for internal antenna
implementation in IoT devices, especially in the context of WLAN, WiMAX, 5G
sub-6GHz, and V2X wireless applications.
