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.
