Enhancement of CPW-fed inverted L-shaped UWB antenna performance characteristics using partial substrate removal technique

摘要

For the exchange of high rate information, wide band antennas are needed and their usage increased tremendously now a days. One of the major challenges in the design of Wideband antenna is the design of a small size antenna while providing wide bandwidth, omni-directional radiation pattern and stable gain. The proposed antenna consists of a monopole patch loaded with truncated L-shaped strip. The ground is extended vertically towards the two sides of the single radiator to improve the bandwidth. The size of the proposed antenna is 25 × 25 × 1.6 mm3 and is prototyped on FR4 substrate whose permittivity is 4.4. The proposed antenna is providing wideband characteristics with suitable gain for wireless communication applications.
