Development of A 28 GHz 5G Wideband Novel Compact Antenna for Wireless Body-Centric Network in Medical Applications

the use of smart wearable gadgets has exponentially increased due to wireless technology advancements. The demand for wireless bandwidth is increasing, and millimeter-sized bands are gradually becoming more prominent. This study presents an analog 28 GHz manufactured F-slotted patch antenna for body-centric communications. The F-slot is carved on a 9.74 mm by 8.5 mm square patch. On top of the slotted patch is a 1.6-mm-dense FR-4 (flame-retardant) substrate with an approximate 4.3. The inclusive dimensions are 12 × 12 × 1.6 (mm), with a packed ground plane the same as the substrate. The antenna has been designed and assessed in a microwave studio using computer simulation technology (CST). A virtual human body model was created within the 3D computer-simulated environment, and simulations were repeated with four equally spaced distances taken into account to more precisely identify the antenna and its behavior. This was done to support the eligibility of this design for WBAN applications. Even when positioned at any distance higher than 2 mm to the human body.
