Compact loop-coupled spiral antenna for multiband wireless USB dongles

Research output: Contribution to journalArticlepeer-review

Abstract

A compact spiral antenna with a loop element for wireless USB dongle devices is proposed. The proposed loop-coupled spiral antenna covers the WiBro, Bluetooth, WLAN, WiMAX and satellite digital multimedia broadcast (S-DMB) bands. The overall dimensions of the fabricated antenna are 10×50×1mm, which is the most compact dimension among multiband USB dongle antennas reported to date. The measured -10dB reflection bandwidths for two resonant frequencies are 19.0 (2.29-2.77GHz) and 27.6 (4.55-6.01GHz). The measured peak gain of the antenna is 3.92dBi.
