Planar Microstrip Slot Antenna for S & C band Wireless Applications ...

A novel design of a multi band microstrip antenna is presented in this work. The double .... The gain radiation pattern at solution frequency is shows in Fig. 10.

Fig 5 shows the radiation pattern of the antenna with slot and shorting wall. There is a strong electric field at the top of the antenna where the slot is present This shows that the slot acts as a capacitive coupling structure so as to produce the required electric field at the required frequency. Figure shows the radiation pattern of the antenna without slot and shorting wall. There is lack of electric field at the top of the antenna which is not suitable for detecting the tags. Fig6 ... Basic Antenna Theory - Wireless •The radiation pattern of antenna is a representation (pictorial or mathematical) of the distribution of the power out-flowing (radiated) from the antenna (in the case of RADIATION PATTERN OF PATCH ANTENNA WITH SLITS The designed Microstrip patch antenna with four slits and a pair of truncated corners are simulated using CADFEKO for finding the electric far field radiation, gain, directivity, radiation pattern e.t.c. Microstrip Antennas: The Patch Antenna

Return loss and radiation pattern are measured with the microstrip antenna as the receiver and shown in Figures 10.34 and 10.35, respectively. A transmitter made of traditional dipole antenna is used and the transmitter–receiver distance is 42 m. The radiation pattern and the signal level are close to expected data.

than the conventional rectangular patch antenna. Satisfactory radiation pattern is also obtained through simulation. The maximum gain in frequency band is 6 dBi. The return loss of -46 dB is also achieved. Index Terms— H-shape patch, Microstrip antenna, bandwidth. 1. Introduction The Microstrip antennas, for its low profile planar configuration, ease of fabrication and integration with RF devices, are being used for many applications due to key advantages over conventional antenna[1-2 ... Design and Development of an Annular Slot Antenna (ASA) with a ... the radiation pattern of an Annular Slot Antenna (ASA) keeping constant the frequency of operation. The planar antenna is fabricated on the top side of a Duroid substrate and the microstrip feeding line with the matching network is fabricated on the back side of the board. The design frequency is 5.8 GHz. Pin diodes are used to short the ASA in pre-selected positions along the circumference. As a result of the short, the direction of the null in the plane defined by the circular slot changes ...
