Design Truncated Corner Rectangular Patch Antenna with Multiple Slot Used in High Altitude Platform Station

High Altitude Platform Station (HAPS) is one alternative in the limitations of BTS and satellite. HAPS technology has advantages that can cover the shortcomings of terrestrial and satellite technology. In this paper, a design of coax-fed rectangular microstrip patch antenna is proposed, in case determining antenna parameters based on WLAN application on communication platform for approach of using HAPS. A truncated corners rectangular microstrip antenna is designed at frequency of 2.4 GHz using multiple slot feeding by coax-fed feeder. The antenna uses an FR-4 epoxy material with a thickness of 1.6mm connected to a 50 Ω connector. The various parameters such as return loss, bandwidth, gain, radiation pattern and VSWR have been analyzed by software. This antenna has a total dimension 28,64 mm × 28,64 mm. The result shows that the proposed antenna is suitable for HAPS due to its small size and thickness.
