Dual-Band Microstrip Patch Antenna for Wireless Applications Keywords: Microstrip, dual-band, wireless, wide-band, slot-loaded Abstract A small wideband microstrip patch antenna is introduced. The antenna is designed to function in the 5-6 GHz wireless LAN bands. It achieves multi-band functionality through the addition of a slot … Annular Slot Loaded High-Impedance Ground Plane - … loop antenna over an annular slot loaded ground plane are shown in Section III. Section IV presents a parametric analysis of the ground plane’s effect using a numerically simulated broadband spiral antenna, including parametric analysis of the slot ring radius, slot … Radio Directional Finding (RDF) Antennas - ThomasNet Standard DF antenna models are typically broadband antennas covering frequencies across the communications bands from HF through UHF or approximately 2.0 MHz to 2700 MHz. The most common design is a cavity-backed annular slot that incorporates ferrite elements for the lower HF frequency range. Manufacturer of radio directional finding (RDF ...
