Bandwidth-Enhanced Low-Profile Cavity-Backed Slot Antenna by Using Hybrid SIW Cavity Modes
TL;DR: In this paper, a low-profile substrate integrated waveguide (SIW) cavity-backed slot antenna is presented, where two hybrid modes, whose dominant fields are located in different half parts of the SIW cavity are two different combinations of the and resonances.
Journal ArticleDOI
A Compact Hepta-Band Loop-Inverted F Reconfigurable Antenna for Mobile Phone
TL;DR: In this article, a folded loop-inverted F reconfigurable antenna for mobile phone applications is designed and the obtained results are discussed in this communication, which operates in hepta-band, including GSM850, GSM900, GPS, DCS, PCS, UMTS and WLAN, with the return loss lower than 6 dB.
Journal ArticleDOI
Compact Azimuthal Omnidirectional Dual-Polarized Antenna Using Highly Isolated Colocated Slots
TL;DR: In this article, an omnidirectional dual-polarized antenna with high port isolation is presented for 2.4-2.48 GHz wireless local area network (WLAN) applications.
Journal ArticleDOI
Compact Heptaband Reconfigurable Loop Antenna for Mobile Handset
TL;DR: An internal folded reconfigurable loop antenna for mobile handset applications is designed, built, and tested, and the efficiency and gain with the p-i-n diodes with their bias circuit are measured and analyzed.
Journal ArticleDOI
Experimental Analysis of a Wideband Pattern Diversity Antenna With Compact Reconfigurable CPW-to-Slotline Transition Feed
TL;DR: In this article, a wideband antenna with a reconfigurable coplanar waveguide (CPW)-to-slotline transition feed is proposed for pattern diversity applications, where changes between modes are controlled by only two p-I-n diodes.
