Compact SIW Based Planar Inverted F Antenna

Compact multiband Planar Inverted F Antenna (PIFA)

A compact planar inverted-F antenna with a PBG-type ground plane for mobile communications

The ground plane affects the characteristics of a planar inverted-F antenna (PIFA) significantly. Using the idea of the high-impedance surface to construct the ground plane, a new type of compact PIFA with a photonic bandgap type (PBG-type) ground plane is proposed. Both the traditional PIFA and the proposed antenna are analyzed using the finite-difference time-domain (FDTD) method in detail. I...

Implementation of Spiraled Planar Inverted–F Antenna for Multiband Applications

A spiraled planar inverted-F Antenna (PIFA) for Multiband frequencies of 2. 65 GHz, 4. 10GHz and 5. 85GHz for wireless local area network (WLAN) applications proposed in this paper. Simulation tool based on the method of moments (IE3D) has been used to analyse and optimize the antenna. The proposed antenna possesses the properties of good performance, compact size (about 50% of a typical PIFA),...

Effects of Substrate Permittivity on Planar Inverted-F Antenna Performances

This paper quantifies the gain and matching bandwidth variations of a planar inverted-F antenna (PIFA) for several dielectric substrates. The performance of the PIFA is assessed in two configurations. First, the PIFA is studied with different substrates for a radiating patch of fixed dimensions of 4.92 cm x 2.13 cm. The effects of the dielectric constant of the perfect and lossy substrates on t...

Wideband Planar Inverted-F MIMO Antenna with High Isolation

A wideband planar inverted-F MIMO antenna with high isolation is proposed in this letter. The proposed MIMO antenna consists of two back-to-back planar inverted-F antennas and a forkshaped decoupling stub. The two planar inverted-F antennas are merged together with a shorting strip connected to the ground plane. In order to enhance the isolation, a fork-shaped decoupling stub connected to the g...
