    This paper presents a triple-band antenna using interdigital technique based on dipole structure at a frequency of 1.8 GHz. Using this technique, harmonic frequency bands can be generated as desired, resulting in the resonance frequencies of the second and third harmonics at 2.4 and 5.2 GHz, respectively. The proposed antenna consists of two square brass plates with an overall size of 63 × 64 mm<sup>2</sup>. The antenna bandwidths are found to be 410 MHz (1.59–2.00 GHz), 70 MHz (2.40–2.47 GHz), and 790 MHz (4.99–5.78 GHz), and the gains obtained are 9.63, 8.95, and 8.97 dB, respectively. The radiation patterns are directional at all frequency bands. Therefore, the proposed antenna can be appropriately used for indoor long-term evolution (LTE) and wireless local area network (WLAN) base stations. © 2018 Institute of Electrical Engineers of Japan.

    This paper proposes a triple band antenna using interdigital technique based on a planar dipole structure. The antenna has been designed at the fundamental frequency of 1.8 GHz. With this proposed technique, the harmonic frequency bands of 2.45 and 5.2 can be created. The designed antenna can support various applications including indoor LTE, WLAN and wireless sensor base station systems. The simulation results of the antenna show superior characteristics in form of return loss and radiation pattern.
