Design and Fabrication of “Ha ()” Shape-Slot Microstrip Antenna for WLAN 2.4 GHz

Part of the Lecture Notes in Electrical Engineering book series (LNEE,volume 365)

Abstract

This paper, a (is read “Ha”) shaped slotted microstrip antenna is designed, fabricated and analyzed. The proposed antenna used -shape slot is to improve return loss and operate for wireless LAN 2.4 GHz frequency band. The proposed antenna utilize transmission line model for analysis and simulation for return loss as well as VSWR with the support CST studio software. After doing some optimization on simulation, finally the dimension of microstrip patch antenna (MSPA) which operated on WLAN frequency 2.4 GHz is obtained. The best simulation results are then used as reference for MSPA fabrication on FR4 substrate with dielectric constant \( \left( {\varepsilon_{\text{r}} } \right) = 4.3 \) and thickness (h) = 1.5 mm. The measurement result shows that the -slot microstrip antenna can achieve return loss (S11) −29.81 dB and VSWR 1.068 at 2.4640770 GHz. The proposed design shows that shape technically can be used as slot within patch to improve microstrip antenna performance.
