Summary
Wideband microstrip antenna with L-plate capacitively coupled feed structure is designed. The antenna operates in GSM 1800/1900 (1710-1910 MHz) and UMTS I (1920-2170 MHz) frequency bands. The antenna has dual slant (+/- 45 degrees) polarization with high isolation (>25 dB) between the ports. Measurements of the antenna reveal good performance in terms of impedance match, gain, gain flatness, isolation, half-power beamwidth, cross-polarization level, and front-to-back ratio. The proposed antenna can be used in base station antenna arrays, pico-cell, and femto-cell small-area cellular networks.
