Multi-Band Stacked Microstrip Patch Antenna with Wide Ground Slot for Wireless Communications
Keywords:
Coupling structure, ground slot, multiband, probe feed, stacked microstrip antennaAbstract
Recently the requirement of low-profile antennas for wireless communications has greatly increased the demand of microstrip antennas because of their low-profile and light weight characteristics. In this paper a miniaturized, multiband dualstacked probe fed microstrip antenna is presented. There exists S-shaped coupling structure between the patches and a wide ground slot to improve antenna characteristics. The proposed antenna operates at six resonant frequencies (S11 below -10 dB), and is thus suitable for wireless communication applications including DCS, WiMax, WLAN, WiBro, Bluetooth and C-band
applications such as satellite communications, weather radar systems etc. The proposed antenna is simulated using IE3D software and has bi-directional radiation patterns with a peak gain of 5.11dB.
