Experiments of horizontal monopoles on HIP with a bandgap centred at 4. In this research, the design and incorporation of the HIS and FSS structures is to achieve a compact and high-directivity antenna. High-impedance electromagnetic surfaces with a forbidden frequency band Abstract: A new type of metallic electromagnetic structure has been developed that is characterized by having high surface impedance, d sievenpiper high impedance electromagnetic surfaces ph d dissertation.
The improvement in the peak gain and the change in the far field pattern can be seen in the simulated radiation pattern plots in Figures 6 and 7. It is made of continuous metal that conducts dc current and eliminates ac d sievenpiper high impedance electromagnetic surfaces ph d dissertation current with a certain bandwidth. In this Antenna instead of normal reflectors we use a high impedance surface reflector.
