A novel coax-fed wideband loop antenna loaded with rectangular patches and U-shaped elements is presented and studied. By inserting a pair of rectangular patches inside the strip loops and employing a pair of U-shaped elements as the parasitic resonators, two additional resonances are excited and a good performance of bandwidth enhancement can be obtained. The measured results indicate that the impedance bandwidth (VSWR•2) is about 87.1% from 1.58 to 4.02GHz, which covers the required operating bands of DCS1800 (1710{1880MHz), PCS1900 (1850{1990MHz), UMTS2100 (1920{ 2170MHz), WLAN2400 (2400{2484MHz), LTE2300/2500 (2300{ 2690MHz) and WiMAX3500 (3300{3690MHz). In addition, good radiation characteristics such as symmetrical radiation pattern, moderate peak gain, low back radiation, and low cross-polarization are observed over the entire operating band.
