Dual-band chip antenna using LTCC multilayer technology for mobile communication applications

A new type of stacked meander chip antenna using LTCC multilayer technology for dual-band operation is proposed; its dimensions are 9 mm × 15 mm × 1.2 mm. By changing the vertical and horizontal lengths of the meander antenna appropriately, we can obtain the desired resonant frequency. With the 2.0:1 VSWR impedance bandwidth definition, the lower and upper bands have impedance bandwidths of 80 MHz and 120 MHz, covering the bandwidths for GPS/K-PCS. Satisfactory agreements between simulated and measured results on antenna patterns and impedance bandwidths have been achieved. Therefore, the proposed antenna is suitable for practical applications requiring a small chip antenna in mobile communication.
