Abstract

We designed and fabricated electrically small antenna (ESA) with a coplanar transmission line-based matching circuit on a printed circuit board. The matching circuit is realized by applying band-pass filter (BPF). Moreover, we designed a dual band antenna by connecting two ESAs with BPF-based duplexer. Our proposed dual band antenna is designed and simulated by using commercial three-dimensional electro magnetic (EM) field simulator. Also, we fabricated this dual band antenna on FR4 substrate and measured the frequency characteristics.
