Tri-Band Bidirectional Antenna for 2.4/5 GHz WLAN and Ku-Band Applications

Abstract

A compact tri-band, low profile, and lightweight antenna is proposed for 2.4/5 GHz WLAN and Ku-band applications. The antenna geometry was a radiating rectangular patch surrounded by a wide circular slot with an inverted-L strip connected to one side of the slot. It was mounted on a copper layer of a single side FR4 substrate with a dielectric constant of 4.3 and a height of 1.6 mm. It was fed by a 50-Ω coplanar waveguide. This design was very compact (40 × 40 × 1.6 mm3). Simulated and actual measurements of an antenna setup in the laboratory verified that the antenna’s bidirectional radiation pattern completely covered the three transmission bands: 2.4–2.485 GHz, 5.15–5.825 GHz and 13.4–17.7 GHz with less than 10-dB return loss and maximum gains of 2.35 dBi, 4.41 dBi and 4.71 dBi, respectively. Wireless communication for the self-navigated vehicle, for one example, is fully supported by this single antenna.

A Low-Profile Antenna for On-Body and Off-Body Applications in the Lower and Upper ISM and WLAN Bands

“…Due to the modifications in wireless communication devices, improvement in antenna design is also required [ 1 ]. The compact, multiband, geometrically simple, and low-profile antennas are the required candidates for current and future wireless communication systems [ 2 ].…”

Metamaterial Based Ku-Band Antenna for Low Earth Orbit Nanosatellite Payload System

“…A linear polarized dual-band patch dipole antenna was developed in [ 8 ] for Ku and Ka-band uses, with resonant frequencies at 16.5 and 32.5 GHz. In [ 9 ], a larger size patch antenna was presented for S, C and Ku band frequencies. The antenna shows the resonant frequency at 2.4, 5.0, and 15.5 GHz frequencies with a low gain value.…”
