Kertas kerja ini mencadangkan antena supergain satu arah berprofil rendah yang boleh digunakan untuk peranti komunikasi wayarles seperti terminal mudah alih, Internet Perkara dan sebagainya. Antena yang digunakan untuk sistem sedemikian dikehendaki bukan sahaja berprofil rendah secara elektrik tetapi juga tidak mudah terdedah kepada objek sekeliling seperti badan manusia dan/atau peralatan elektrik. Antena yang dicadangkan mencapai kedua-dua keperluan kerana sifat supergainnya menggunakan elemen planar dan reflektor planar yang diletakkan rapat. Antena utama ialah jenis dipol asimetri, dan terdiri daripada elemen monopole yang dipasang pada tepi satah konduktor segi empat tepat. Kedua-dua elemen diletakkan pada substrat dielektrik yang disokong oleh reflektor planar. Secara berangka dan eksperimen ditunjukkan bahawa sifat supergain dicapai dengan mengoptimumkan parameter geometri antena. Ia juga menunjukkan bahawa ciri impedans boleh dilaraskan dengan jayanya dengan menukar panjang elemen satah tanah dan unsur monopole. Oleh itu, tiada litar pemadanan impedans tambahan diperlukan. Tambahan pula, ia menunjukkan bahawa objek di sekeliling mempunyai kesan yang tidak ketara ke atas prestasi antena.

Abstract: This paper proposes a low-profile unidirectional supergain antenna applicable to wireless communication devices such as mobile terminals, the Internet of Things and so on. The antennas used for such systems are required to be not only electrically low-profile but also unsusceptible to surrounding objects such as human body and/or electrical equipment. The proposed antenna achieves both requirements due to its supergain property using planar elements and a closely placed planar reflector. The primary antenna is an asymmetric dipole type, and consists of a monopole element mounted on an edge of a rectangular conducting plane. Both elements are placed on a dielectric substrate backed by the planar reflector. It is numerically and experimentally shown that the supergain property is achieved by optimizing the geometrical parameters of the antenna. It is also shown that the impedance characteristics can be successfully adjusted by changing the lengths of the ground plane element and the monopole element. Thus, no additional impedance matching circuit is necessary. Furthermore, it is shown that surrounding objects have insignificant impact on the antenna performance.
