A 4×1 L-probe fed Inverted Hybrid E-H Microstrip Patch Antenna Array for 3G Application

Design of meandering probe fed microstrip patch antenna for wireless communication system

“…The peak cross-polarization level of the antenna is observed to be about -50dB and -23dB below the copolarization level of the main lobe at xz-plane and yz-plane respectively at the frequency of 1.88 GHz. The proposed patch antenna exhibits better cross polarization than the design reported in [10]. Notable, the radiation characteristics of the proposed patch antenna are better to those of the conventional patch antenna.…”

“…The design employs contemporary techniques namely, the meander probe feeding, inverted patch, and proposed patch techniques to meet the design requirement. A better crosspolarization is achieved compared to the design reported in [10].…”

“…These capacitances can suppress some of the inductance contributed by the vertical portions of the probe and hence, achieve low cross-polarization. In addition, the antenna has better cross-polarization in comparison with the slotted antenna described in [10].…”
