Abstract

This letter presents a new printed slot loop antenna with a pair of tunable strips for wireless communication systems in 2.4-GHz (2.40-2.48 GHz) and 5-GHz (5.15-5.95 GHz) bands. If a pair of the strips is inset at the center of the slot loop antenna, then the resulting impedance bandwidth for the two main operating bands can reach about 100 MHz for the 2.4-GHz band, and 1550 MHz for the 5-GHz band, thus covering the required operations of a wireless local area network (WLAN). Experimental results confirm in detail several properties of the proposed antenna design, such as the impedance bandwidth, radiation pattern and measured gain.
