A dual-band microstrip patch dipole-loop antenna with the reflector element is presented in this paper. The study focuses on the gain enhancement for a dual-band quasi-Yagi antenna by using a copper plate as a reflector. The antenna is simulated and realized on FR4-epoxy substrate and contains two different radiating elements and two different bands; a loop and a dipole geometry, operate 2.4 GHz and 3.5 GHz, respectively. The gain of the antenna is increased from 1.3 dB to 6.5 dB for 2.4 GHz and 5.2 dB to 8.3 dB for 3.5 GHz with required radiation characteristics. The antenna has a dual-band characteristic that may have a usage in the 5G mobile communication and Wi-Fi applications. The purpose is to minimize the reflector dimensions to have a compact and cheap antenna structure. This antenna is designed for the system bridging remote control of indoor or outdoor application via operators using 5G technology. By using the proposed antenna devices can connect to a 5G network and be controlled from outside automatically. By increasing the directivity, the power consumption is reduced and the service quality is increased.
