This paper presents a novel design of a compact Ultra-wide band textile antenna which operates from the frequency range of 2.8–14 GHz, covering the entire ultra-wide band frequency range of 3.1–10.6 GHz, as approved by FCC. Hybrid design technique is applied to a simplified circular patch design and finally an octagonal shape is achieved that exhibits ultra-wide band characteristics. The substrate of the designed antenna is made of jeans fabric (ɛr = 1.7) while patch and the ground plane is made of copper tape. The dimension of the substrate is 42 × 34 mm2. A partial ground plane with a square notch is placed at the back of the substrate. This antenna performance is also analyzed at six different bending angles. The characteristics, low profile, and compact size of the proposed antenna depicts as a potential candidate for ultra-wide band applications. The antenna design details and simulated results are presented by CST Microwave Studio.Keywords: ultra-wide band, textile antenna, octagonal patch, partial ground, slot
