Abstract

A design of a low‐profile and printed array antenna for wireless access points and futuristic healthcare devices is presented in this manuscript. The antenna design is derived from a printed dipole configuration and is optimized using an empirical design approach to achieve enhanced bandwidth, gain and efficiency performances. The antenna is printed on Rogers RT‐5880 laminate with a permittivity of 2.2 and a thickness of 0.508 mm. The overall footprint of the design covers 27.5 × 39.1 mm2 on a substrate of 36 × 42 mm2. Results have shown that the design covers a wide bandwidth of more than 7 GHz, making it capable of covering 40.5–42.5 GHz, 42.5–43.5 GHz, 45.5– 47 GHz and 47–47.2 GHz 5G bands as recommended in WRC‐15. The design shows an average gain of 11.5 dB and an average efficiency of 84% over the entire bandwidth. The simulation and measurement results mostly agree, with minor disparities which might have been caused due to substrate tolerance and testing setup.
