Abstract :
By embedding shorting vias, a broadband and dual-frequency L-probe fed microstrip antenna, with flexible frequency ratio and relatively small lateral size, is proposed. The measured impedance bandwidth (S11<10dB) of the two operating bands can reach 26.6% and 42.2%, respectively. Also the radiation patterns are stable in both operating bands. Simulation results are compared with experiments and a good agreement is observed. This antenna is highly suitable for modern mobile base station transceivers.
