Analytical Study of Radial Gap Capacitance for Probe Feed Rectangular Microsrip Patch Antenna
Microstrip patch antennas are known to have a narrow bandwidth. Several techniques have been introduced to improve the bandwidth of microstrip patch antennas. Most of these attempts to increase the bandwidth. There have been many efforts to reduce the cross polarization and achieve wideband performance. One of the most common approaches to increase the bandwidth of a microstrip patch antenna. In this paper, impedance (i.e. coaxial feed probe) is matched with patch of the microstrip antenna. At resonant frequency 3.137GHz.
