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),...

Study of Planar Inverted-F Antenna (PIFA) for Mobile Devices

Now-a-days more and more radios are being integrated into a single wireless platform to allow maximum connectivity. In this paper a theoretical study of Planar Inverted F Antenna is presented. PIFA as a low profile antenna is widely used in several application areas due to several advantages. Research and experiments done on PIFA structures are discussed and categorized. Some methods that can b...

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...
