Abstract

Kertas kerja ini menyampaikan antena mikrostrip tampal baru berjalur lebar bentuk hibrid E–H tersongsang tersuap prob–L (LIEH) yang merangkumi jalur International Mobile Telecommunications – 2000 (IMI–2000). Reka bentuk ini menggunakan teknik terkini; penyuapan prob–L struktur tampal tersongsang dengan substratum udara, dan tampal penyinar beralur. Kesan komposit dengan mengintegrasi teknik ini dengan penggunaan bentuk tampal hibrid E–H, menawarkan ciri–ciri berprofil rendah, berjalur lebar luas, gandaan tinggi, pengutuban silang rendah, dan elemen antena yang padat. Keputusan pengukuran adalah memuaskan dengan pencapaian lebar jalur 17.20% pada kehilangan kembali 14 dB (SWR = 1.5), gandaan maksimum 8 dBi dengan variasi gandaan 1 dB, dan pengkutuban silang 23 dB di bawah aras cuping utama. Tampal LIEH mempunyai dimensi yang padat iaitu 79 × 41 mm2. Reka bentuk ini sesuai bagi aplikasi tatasusun terutamanya bagi antena stesen tapak IMT–2000. Kata kunci: IMT-2000, antena jalurlebar luas, antena tampal mikrostrip, antena tampal bentuk E-H, suapan prob-L This paper presents a novel wideband L–probe fed inverted hybrid E–H shaped microstrip patch antenna (LIEH) covering the International Mobile Telecommunications – 2000 (IMT–2000) band. The design adopts contemporary techniques; L–probe feeding, inverted patch structure with air–filled dielectric, and slotted patch. The composite effect of integrating these techniques and introducing the novel E–H patch shaped offers a low profile, broadband, high gain, low crosspolarization, and compact antenna element. Measurement result showed satisfactory performance with an achievable bandwidth of 17.20% at 14 dB return loss (SWR = 1.5), maximum achievable gain of 8 dBi with 1 dB gain variations, and crosspolarization level of 23 dB below the main lobe level. The LIEH patch has a compact dimension of 79 × 41 mm2. The design is suitable for array applications especially for IMT–2000 base station antenna.
