  ABSTRACT: A compact, multiband, planar, and low-profile wide- band code division multiple access (WCDMA)AVLAN antenna is presented in this letter. A metallized dielectric loading technique using a low-cost FR4-type material has been implemented to achieve a small footprint of 18 × 21 mm² instead of using expensive ceramics. The WCDMA/WLAN antenna achieves multiband operation with good impedance matching and radiation behavior. Antenna measurements are presented to validate the simulations.

  ABSTRACT: A new method to increase the gain of a conventional microstrip patch antenna is presented. A rectangular loop shaped parasitic radiator placed a specific distance away from the patch surface increases the gain by about 3.3 dB. The impedance and radiation performances of the proposed antenna are presented with excellent agreement between simulated and measured results.
