Abstract
A simple and compact, self-isolated printed antenna able to operate in the 2.4 GHz (2400-2484 MHz) and the 5 GHz (5150-5825 MHz) wireless local area network (WLAN) bands in notebook computers is introduced. The design is built on a low-cost substrate with the dimensions 6 mm × 30 mm (about 0.05λ × 0.24λ at 2.4 GHz) and comprises a symmetrical coupled-fed loop and two parasitic shorted strips. For size reduction, the 2.4 GHz loop is loaded with a pair of L-shaped stubs above the feeding and coupling T strip. The parasitic strips shorted on both sides of the coupling T strip are further added to generate the 5 GHz band resonance. The results show that good radiation characteristics can be obtained in the bands of interest. In addition, when grouping three proposed designs with a gap of 4 mm between them, the results for each antenna impedance bandwidth, the isolation between any two of the three designs, and the envelope correlation coefficient (ECC) are also satisfactory.
