Abstract

Configurations of planar cross monopole antennas have been investigated. The cross-shaped patch comprises vertical microstrip and two rectangular patches (area A). Effect of rectangular patches (A) of planar cross monopole antennas on the bandwidth has been studied. Another dielectric substrate (075BCT) is used in order to optimize the size. Those antennas provide wideband characteristic and nearly omni-directional radiation pattern. Simulations and experiments demonstrate that this structure exhibits a wide impedance bandwidth, which is over 70% for S₁₁ les 10 dB ranging from 2.18-4.78 GHz, which is enough to cover DECT/IMT-2000/3G/UMTS/2.45-GHz ISM band (WLAN, IEEE 802.11b and g)/Bluetooth/ZigBee 2.4 GHz/2.5-GHz WiMAX/3.5-GHz WiMAX bands.
