A Low-Cost Dual Band Integratable Antenna for Sub-6GHz Applications

In this paper, a low-cost antenna with dual band characteristics has been presented. For the first band, the proposed antenna fully covers 2.45 GHz, Wireless Local Area Network (WLAN) and Industrial, Scientific, and Medical (ISM) band covering 2.4 – 2.5 GHz band with impedance bandwidth better than -14dB. For the second band, it offers impedance bandwidth w.r.t. better than -14dB for public safety applications. Moreover, the second band also covers 4.8-5.2 GHz band w.r.t. - 10dB impedance bandwidth. It is designed using FR-4 low-cost substrate with thickness of 0.8mm. Moreover, it exhibits good radiation characteristics in terms of radiation patterns and gain. The shape and compactness of antenna allow its easy integration to sub-6GHz devices and IoT applications.
