typical radiation pattern and return loss for slot antenna is shown in Fig.3 and 4 respectively. It is seen that the slot radiates in both planes (both sides of the PEC). Fig.2: Slot antenna and its complementary dipole. Fig.3: Radiation pattern from a slot antenna. Fig.4: Resonance frequency of 2.4 GHz slot antenna. RESONANT LENGTH CALCULATION AND RADIATION PATTERN SYNTHESIS ... Abstract—Main intension is to calculate admittance and radiation pattern of longitudinal shunt slot in rectangular waveguide using Method of Moments (MoM) technique. Resonant length calculation of the slot is a critical parameter in the design of waveguide slot array antenna. All computed results are compared with simulated results. MicroStrip Antenna - SlideShare Radiation efficiency, h, and unloaded radiation Q, Q o, as a functionof substrate thickness .Figure shows that :A microstrip patch that uses a thicker substrate is more efficient.In addition, as the substrate thickness increases, the radiation Q of the antenna decreases.Thus, impedance bandwidth increases with increasing substrate thickness.
