Input impedance-tuning slots of PIFA antennas
2nd European Conference on Antennas and Propagation (EuCAP 2007), 2007Input impedance-tuning methods are proposed for antenna designs of mobile communications devices. The proposed method can be applied to input impedance-tuning of single- band, dual-band and multi-band PIFA (planar inverted-F antenna) antennas. The prominent feature of this impedance-tuning method is to use an inductive-tuning slot or a capacitive ...

Parasitic element and PIFA antenna structure
2009 IEEE Antennas and Propagation Society International Symposium, 2009An PCE is proposed that uses available space in the phone housing effectively and adds additional bands to existing PIFA. The PCE can be used advantageously to add a GPS band to a cellular band PIFA but other uses such as adding bands in the WiFi and WiMax bands are also possible.

Reconfigurable PIFA antenna with ultra wideband tuning
2nd European Conference on Antennas and Propagation (EuCAP 2007), 2007A reconfigurable PIFA antenna is presented in this article. It is 60×114×4 mm and can achieve through multiple configurations a total matched bandwidth of 0.6 to 6.7 MHz, at -10 dB. Simulation results with perfect components are presented. Then the impact of real components on both matching and radiation pattern is studied, using a PIN diode model and ...

A new dual feed PIFA diversity antenna
The 8th European Conference on Antennas and Propagation (EuCAP 2014), 2014A new wideband, very low profile (3 mm), PIFA antenna is proposed. It utilizes two collinear feeds, ground plane slots and modified top radiating plate to reduce the mutual coupling between the feeds and improve the impedance matching. The proposed antenna has a 10-dB impedance bandwidth from 2.25 to 3.2 GHz or a fractional bandwidth of 35 %. It covers

A novel PIFA antenna for broadband circular polarization
Microwave and Optical Technology Letters, 2010AbstractA novel broadband circularly polarized antenna is proposed, designed, and measured. Basically, the antenna consists of a PIFA and a square ground with an arrow‐like branch at its corner, which permit the antenna both broadband and circular polarization characteristics.
