WCDMA 3G and 4G LTE [4]. A dual frequency resonance antenna is achieved by introducing U shaped slot in semicircular disk. It is analyzed by using circuit theory concept. It is found that the resonant frequency depends inversely on the slot length and feed point while it increases with increasing the slot width and coaxial probe feed radius [5]. In recent years, some papers were reported for dual/triple band operation by using single/double U slot in the microstrip antenna. It is seen that ...

First, the length of the patch L controls the resonant frequency as seen here. This is true in general, even for more complicated microstrip antennas that weave around - the length of the longest path on the microstrip controls the lowest frequency of operation. Equation (1) below gives the relationship between the resonant frequency and the patch length: ex W1GHZAntenna Book W1GHZAntenna BookW1GHZAntenna Book Microwave ... 7.2.3 Waveguide slot array design A sketch of a waveguide slot antenna with the pertinent dimensions is shown in Figure 7-5. The first design consideration is that the slots be resonant so that they provide a resistive load to the Formulation of Resonance Frequency for Dual band Slotted H-shaped ... The dual band H-shaped microstrip antenna realized by cutting a U-slot or pair of rectangular slots is proposed. They give dual band response with broadside radiation pattern. To understand the mode introduced by the slot, the analysis for slot cut H-shaped antennas is carried out by studying their surface current distributions out over a wide frequency range. It was observed that neither of the U or rectangular slots introduce any mode but they alter the higher order mode resonance ...
