Slot antenna resonant frequency formula

By Author

While this type of antenna is not used as much as it once was, the theory behind this antenna has led to many of the more modern antennas such as the IFA, PIFA, and FICA antennas. All the equations for determining the size and impedance of …

Progress In Electromagnetics Research Letters, Vol. 3, 187–195, 2008 RESONANT LENGTH CALCULATION AND RADIATION PATTERN SYNTHESIS OF LONGITUDINAL SLOT ANTENNA IN RECTANGULAR Antennas: Cavity-Backed Slot Antennas - Antenna Theory This cavity-backed slot antenna has a first resonance at about 2.45 GHz. At this frequency, the cavity backed slot antenna is roughly 0.474 wavelengths long - which is roughly the length of a resonant dipole antenna . Microstrip Patch Antenna Designing at 2.4 GHz Frequency simple microstrip patch antenna is designed in CST Microwave Studio at a resonant frequency of 2.4 GHz. The gain of the designed The gain of the designed antenna is 8.27 dB and VSWR of 1.18. Non-Resonant Slotted Waveguide Antenna Design Method
