Ismail Delta Higher Institute for Engineering and Technology, Talkha, 35111, Mansoura, Egypt A new shape of slot antenna (U-shaped) is introduced in this paper. The proposed antenna is designed for use in mobile phone devices. This structure covers bands ISM/Bluetooth, WLAN, Wi-Fi, WiMAX, 5G applications, cellular communications, weather radar, surface ship radar, and some communications satellites. A U-shaped slot is cut on the ground plane. A coupling feed technique is used to feed the designed antenna. The proposed antenna is printed on a high-loss FR-4 dielectric substrate with style='mso-bidi-font-style:normal'> "Cambria Math",serif;mso-fareast-font-family:"Cambria Math";mso-bidi-font-family: "Times New Roman";mso-bidi-theme-font:major-bidi'> style='mso-spacerun:yes'> style='font-size:10.0pt;mso-ansi-font-size:10.0pt;mso-bidi-font-size:10.0pt; font-family:"Cambria Math",serif;mso-ascii-font-family:"Cambria Math"; mso-fareast-font-family:"Cambria Math";mso-hansi-font-family:"Cambria Math"; mso-bidi-font-family:"Times New Roman";mso-bidi-theme-font:major-bidi'> style='mso-bidi-font-style:normal'> "Cambria Math",serif;mso-fareast-font-family:"Cambria Math";mso-bidi-font-family: "Times New Roman";mso-bidi-theme-font:major-bidi'>ε style='mso-bidi-font-style:normal'> "Cambria Math",serif;mso-fareast-font-family:"Cambria Math";mso-bidi-font-family: "Times New Roman";mso-bidi-theme-font:major-bidi'>r style='mso-bidi-font-style:normal'> "Cambria Math",serif;mso-fareast-font-family:"Cambria Math";mso-bidi-font-family: "Times New Roman";mso-bidi-theme-font:major-bidi'>=4.4 . The designed antenna achieves a very wide bandwidth (from 2.3GHz to 6.3GHz). A high gain (around 7dB) is also achieved. The design is simulated using CST software, and the results are verified by HFSS software. 2022 77 83 1570 https://creativecommons.org/licenses/by/4.0/ 10.54216/IJWAC.050206 https://americaspg.com/journal/20/article/1570 https://americaspg.com/storage/51677028490.pdf
