Slot loaded electromagnetically coupled microstrip line fed microstrip patch antenna for wideband applications

A simple, E-shaped slot loaded wideband microstrip patch antenna with square shaped parasitic element is presented in this paper. The antenna is printed on a dielectric substrate, and directly fed from a 50 Ω microstrip line. Using IE3D software package of Zeland, according to the set size, the antenna is simulated. The composite effect of integrating these techniques and by introducing the E-shaped slotted patch offers a low profile, wide bandwidth, and compact antenna element. The computer simulation results show that the antenna can realize wide band characters. With adjusted parameters, it exhibits a broad impedance bandwidth (VSWR ≤ 2) of about 96.94% (1.35 GHz-3.89 GHz). The proposed antenna can be used in the UMTS (1.92-2.17 GHz), Wi-max (2.2-3.4 GHz), WLAN (2.40-2.48 GHz), and UMTS II (2.50-2.69 GHz) frequency bands.
