In this work we propose a methodology design of a dual band small antenna. On a 3.5 GHz conventional rectangular patch antenna, we have applied two miniaturization techniques. The first technique is to reduce the ground plane of the conventional antenna, while the second technique is to each an epsilon negative metamaterial unit cell at 2.45 GHz on its patch. The proposed antenna covers two frequency bands: the lower band at -10 dB is 108 MHz, ranging from 2.3859 GHz to 2.4939 GHz. The upper band at -10 dB is 730 MHz, ranging from 3.07 GHz to 3.8 GHz. The gain at their central frequency 2.45 GHz and 3.36 GHz are respectively 2.66 dBi and 3.47 dBi. The materials used in the antenna design are copper for the conductive parts and the FR-4 epoxy, with relative permittivity of 4.4 and a thickness of 1.6 mm, for the antenna substrate.

摘要

In this work we propose a methodology design of a dual band small antenna. On a 3.5 GHz conventional rectangular patch antenna, we have applied two miniaturization techniques. The first technique is to reduce the ground plane of the conventional antenna, while the second technique is to each an epsilon negative metamaterial unit cell at 2.45 GHz on its patch. The proposed antenna covers two frequency bands: the lower band at -10 dB is 108 MHz, ranging from 2.3859 GHz to 2.4939 GHz. The upper band at -10 dB is 730 MHz, ranging from 3.07 GHz to 3.8 GHz. The gain at their central frequency 2.45 GHz and 3.36 GHz are respectively 2.66 dBi and 3.47 dBi. The materials used in the antenna design are copper for the conductive parts and the FR-4 epoxy, with relative permittivity of 4.4 and a thickness of 1.6 mm, for the antenna substrate.
