An Optimized Half Wave Dipole Antenna for the Transmission of WiFi and Broadband Networks

Abstract

Antenna implementations play a significant role in the field of wireless communication and aid the transmission and reception of electromagnetic wave propagation. The shape, size, and parameters of this crucial system depend on the certain range of frequency band allocation. The WiFi network operates at the spectrum of 2.4GHz to 5.9GHz, and the recent 802.11 standard ranges up to 60GHz. But the coverage area for indoor or outdoor deployment is very narrow which requires efficient antenna coverage from far distance to the access point network. This work proposed an optimized directional half-wave dipole antenna, adaptable for affixation to panel and yagi-uda antennas. This technique of antenna coverage optimization was achieved through the varying of antenna parameters to obtain better performance with reference to 100W rated, 2.4GHz, and 2.18dB gain WiFi half-wave dipole having a range of 150m. The optimized antenna operates at a frequency of 2.4GHz – 5.9GHz with a beam distance of 500m and an improved gain of 4.73dB. This obtained result shows a better performance in comparison to the understudied antenna, which makes it a candidate for WiFi and low-frequency broadband dipole antenna applications.
