  • Antennas: The Inverted-F Antenna (IFA) - Antenna Theory
    Geometry of Inverted-F Antenna (IFA) The feed is placed from the ground plane to the upper arm of the IFA The upper arm of the IFA has a length that is roughly a quarter of a wavelength To the left of the feed (as shown in Figure 1), the upper arm is shorted to the ground plane
  • Inverted-F antenna - Wikipedia
    An inverted-F antenna is a type of antenna used in wireless communication, mainly at UHF and microwave frequencies It consists of a monopole antenna running parallel to a ground plane and grounded at one end
  • PIFA – Planar Inverted F Antenna - qsl. net
    In general, the required PCB ground plane length is roughly one quarter (λ 4) of the operating wavelength If the ground plane is much longer than λ 4, the radiation patterns will become increasingly multi-lobed
  • rf - Designing an Inverted F-Antenna - Electrical Engineering Stack . . .
    I want to use an Inverted F-Antenna for my next project, but I'm struggling to find some good design information I have read that the length of the arm "L" is roughly a quarter wavelength of the desired resonant frequency
  • Inverted-F Antenna (IFA PIFA) Design: A Complete Guide to 2. 4 . . . - RayMing
    The basic structure of an Inverted-F Antenna consists of three main parts: Radiating element: A horizontal arm that is typically a quarter-wavelength long at the operating frequency Short-circuit stub: A vertical element connecting one end of the radiating element to the ground plane
  • Inverted-F Antenna Design For a PCB
    This type of antenna is a quarter-wavelength antenna where the operational parameters (bandwidth, impedance, etc ) are set by adjusting the geometry along the quarter-wavelength leg of the antenna An overview of a typical inverted-F antenna is shown below
  • Design and Simulation of a Planar Inverted-F Antenna
    The upper arm of the IFA has a length that is roughly a quarter of a wavelength (Figure 1) Figure 1 • Construction of basic IFA with shorting stub (left of feed point) to compensate for capacitive effect of open stub resonator
  • Inverted-F antenna (IFA) – Electricity – Magnetism
    The Inverted-F Antenna is a derivative of the monopole antenna, which is essentially a quarter-wavelength resonant structure The design of an IFA consists of a ground plane, a radiating element, and a shorting pin that connects the radiating element to the ground plane
  • Analysis of a small Inverted F PCB antenna for a 450 Mhz to 470 Mhz . . .
    Simulation results of an inverted F antenna using NEC2 Frequency = 460 Mhz, Length of wire = 0 16 ( cross arm) meter, radius = 1mm free space wavelength = 0 652 meter
  • A Comprehensive Parametric Study of Planar Inverted-F Antenna
    The Planar Inverted-F Antenna (PIFA) can be viewed as evolved from a quarter-wavelength monopole antenna and is now widely used in mobile and portable radio applications due to its many attractive attributes such as simple design, lightweight, low-cost, low-profile, conformal nature and reliable performance [1-4]
