A wideband patch antenna fed by an L-strip feeder is studied. The objective of this paper is to design small wideband antenna for 3G and 4G wireless mobile communication service. The enhanced features were confirmed and proved by comparing the proposed antenna with the antennae that have been reported in the relevant literatures. Measurement results confirm that an impedance bandwidth(VSWR≤2) of 636MHz(32.5%, fo=1,960MHz) is achieved at 3G and 4G frequency band for L-strip-fed triangular patch antenna. In general, probe feed has only the parasitic reactance caused by the probe, which reduces the bandwidth performance of the antenna. The experimental results proved that the effects of improvement could be achieved because the proposed antenna is capable of compensating the parasitic reactance from the feeding mechanism.The studied antenna can be designed easily for extension of array because it has simple structure
