Abstract :A simple square microstrip inset-feed patch antenna with slots for 2.4 GHz of WLAN applications is presented. Our proposed antenna design is a high gain, bandwidth, very low return loss and single band frequency. The antenna is capable to realize return loss (S11) of -45 dB and voltage standing wave ratio (VSWR) equals (1). The antenna can support WLAN applications at 2.4 GHz resonant frequency with bandwidth of 76.278 MHz. The antenna is excited by one port with microstrip inset feed line mechanism. The designed antenna is printed on Flame Retardant 4 (FR-4) substrate with 4.6 dielectric constant. The conducting patch and ground antenna material is copper (annealed). The square microstrip patch antenna has dimensions of 28.45 x 28.45 x 0.035 mm3 of patch plane. The omnidirectional radiation pattern of our antenna is 6.25 dBi. The proposed antenna has been simulated and analyzed through CST microwave studio (MWS) version 2018. The simulation results show that our proposed antenna is considered as a greet solution with an excellent performance to meet the requirements of various modern communication systems.
