Compact Dual-Band Slot Antenna at the Corner of the Ground Plane

A compact design of a dual-band (2.4-2.485 GHz and 5.15-5.825 GHz) slot antenna is proposed for WLAN applications. To achieve compact and practical design, the proposed antenna is composed of narrow slots, and placed in the 10 times 10 mm 2 corner region on a typical FR4 printed circuit board for WLAN personal-digital-assistance (PDA) phones. The detailed design considerations are described in this communication. Also, simulation and measurement regarding the reflection coefficient and radiation pattern are conducted. Good agreement between both results is obtained.
