Compact Band Width Enhanced Microstrip Antenna for WLAN Applications
The microstrip patch antennas are widely used in modern communication system due to low profile, low weight, low cost However, the antennas suffered from narrow bandwidth and low gain. Therefore, various techniques have been proposed in the literature to increase the bandwidth. These include cutting slots in the metallic patch in addition to the common techniques which are increasing patch height and decreasing substrate permittivity. Numerous techniques have been presented to enhance the bandwidth for various communication systems. A single layer wide-band E-shape rectangular patch antenna with achievable good impedance bandwidth has been demonstrated. A new inverted multi-slotted shape patch antenna is investigated for the gain and bandwidth enhancement.
