A compact, planar, multiband antenna with loop and monopole elements suitable for wideband code division multiple access (WCDMA), wireless LAN (WLAN), and ultra wideband (UWB) wireless communications is presented in this paper. The antenna was built on FR4-type substrate and fed by a microstrip transmission line for easy integration with RF/microwave circuitry on the same circuit board. The physical lowband of the antenna includes 1.9?2.17-GHz WCDMA and 2.45-GHz WLAN bands, whereas the high-band spans from about 3.3 to about 11-GHz including 5-GHz WLAN, 3.1?10.6-GHz UWB, and 4?8-GHz C bands. Antenna S11 and radiation pattern measurements are presented. It’s shown that measurements and simulations are in good agreement.
