A circular patch antenna with a narrow slit is proposed to achieve multi frequency, dual band operation. The proposed antenna radiates at four different frequencies with sufficiently high matching with probe feed system. Among these four frequencies two frequencies 2.62 GHz and 5.82 GHz lies in lower and upper frequency band respectively of Wi-Max application created by IEEE 802.16 working group....
A novel single feed miniaturized cross patch antenna radiating at three resonant frequencies is presented. Compared to standard rectangular patches, the proposed antenna gives an area reduction of 82%, 74% and 53% for the linearly polarized radiations with center frequencies at 1.2395 GHz, 1.515 GHz, and 2.027 GHz respectively. The antenna exhibits nearly omnidirectional radiation characteristics...
A dual band RFID applications in 800 - 900 MHz and 2400 MHz band is presented. The Asymmetric Coplanar Strip (ACS) fed antenna consists of inverted L shaped monopole with a capacitive loading to provide necessary impedance matching and current distribution. The antenna has wide bandwidth from 790 MHz to 1050 MHz and from 2350 MHz to 2640 MHz coving the RFID UHF and Microwave frequencies. The uniplanar...
