A compact rectangular patch antenna with narrow crossed slits is proposed in this paper that is resonating at two closely spaced frequencies (3.56 GHz, 3.73 GHz) with improved bandwidth (7.6%). This bandwidth value is more than three times higher than that of a conventional rectangular patch antenna (~2%) having identical patch size and operating under similar conditions. The variation in gain and...
In this paper, the design of a micro strip patch antenna is reported which can be operated at GPS (Global Positioning System) and Bluetooth frequencies. Very small thin micro strip antenna is excited by a co-axial SMA connector to produce centre frequency of a Bluetooth system and the correct feed position is determined for impedance matching. Then a thin parasitic micro strip patch is coupled with...
S-band has been used for satellite telemetry, tracking and control (TT&C) applications for many years and more recently X-band has also been deployed. A theoretical design for a new dual S/X-band feed-system for a ground station with S-band transmit and receive capabilities and X-band receive capabilities is presented.
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....
This communication presents a comparison in the performance of a normal elliptical microstrip patch antenna with same antenna having loading of sector slits. Required number and dimensions of the slits for bandwidth enhancement are optimized for reliable radiating characteristics. It is found that resonant frequency of the unslotted elliptically patch antenna is about 5.62 GHz, with an operating bandwidth...
