Design of a e-slotted loaded circular microstrip patch antenna

Abstract EN

This paper presents a desig n of E slot loaded circular patch microstrip antenna used for co m- munication purposes especially in civil and military applications.

The antenna has been simulated and d e- sign on Arlon AD320A (tm) substrate with dielectric co n stant substrates of 3.2 and optim um dimensions of 29 × 24 × 1.7 mm 3 The design requirements for the antennas i n clude a VSWR < 2 for 50 Ω reference impedance and return loss is less than to 10 dB.

The proposed antenna simulation is carried out using A n- soft HFSS.

The E slot microstrip pa tch antenna was then fabr i cated using microstrip coaxial probe feed arrang e ment and to be determined its S 11 and VSWR result While the dual bandwidths measured for 10 dB reflee c tion coefficient are 0.21 GHz and 0.812 GHz at range (11.9699 12.7820 GH z) or (1.6 % and 6.55%).
