In the present paper notch loaded shorted microstrip patch antenna has been analysed using cavity model. The proposed antenna shows dual band operation which depends on notch dimensions as well as shorting wall. The frequency ratio is found to be 1.5278 for the notch loaded rectangular patch, while in notch loaded shorted patch, the frequency ratio varies from 2.9764 to 2.725 for increasing val...

This paper presents the effective harmonics rejection of dual band rectangular microstrip patch antenna. The dual frequency circular polarization achieved with proper pin shorting at the corner of RMPA. Pin shorting at the corner also process harmonic effect. Using effective corner truncation technique of the rectangular patch, undesired harmonics effect can be rejected completely. The simulati...

A Novel internal triple band folded planar antenna is introduced in this paper. By modifying the geometry and implementing the shorting pins onto two sides folded structure rectangular patch antenna. The size of the folded rectangular patch antenna can be successfully reduced to volume of 34 34 7 mm. An additional microstrip line of 2 8 mm is also incorporated with the proposed patch antenna in...

In this paper, an Artificial Neural Networks (ANN) model has been developed to design the multilayer Rectangular microstrip patch. In the design procedure, synthesis ANN model is used as feed forward network to calculate the resonant frequency. Analysis ANN model is used as the reverse side of the problem to calculate the antenna dimension. The network is trained with the data obtained from mea...

Conventional microstrip antennas in general have a conducting patch printed on a grounded microwave substrate, and have the attractive features of low profile, light weight, easy fabrication, and conformability to mounting hosts [1]. However, mi-crostrip antennas inherently have a narrow bandwidth, and bandwidth enhancement is usually demanded for practical applications. In addition, applicatio...

This article presents the design of a miniaturized microstrip antenna for microwave medical imaging applications. We propose a miniature rectangular printed antenna that meets the UWB characteristics in terms of bandwidth and reflection coefficient. This antenna is designed for a system to detect malignant tumors by microwave imaging. We use certain techniques of miniaturization and expansion o...

The design of an integrated rectangular microstrip patch array antenna with enhanced isolation characteristic between transmitter and receiver is presented to produce a full-duplex transceiver with transmit and receive operation at the same frequency and with the same polarization. This integrated circulator-like antenna has potential uses in both short-range communication systems and radar.

-Wide band truncated rectangular microstrip antenna with H slot loaded and defected ground plane structure is presented in this paper to increase the bandwidth. It is found that the impedance bandwidth of a microstrip antenna could be enhanced considerably when a defected ground structure is used .The band width of a truncated rectangular microstrip antenna with H slot is 21.2% whereas after ad...

The characteristics of a dual-frequency compact antenna, which uses a rectangular microstrip patch with a shorting pin, are studied. Compared with the conventional rectangular patch antenna, this antenna can achieve both a significant reduction of antenna size and a dual-frequency operation with a single feed. A detailed parameter study is performed. The theoretical analysis is based on the fin...

A novel technique for obtaining a single-layer single-feed dual frequency rectangular microstrip antenna with protruding semi ellipse for s-band communication is proposed and demonstrated. By protruding semi ellipse of appropriate dimension close to one of the edge, the rectangular patch has been shown to realize dual-frequency broadside radiations. This dual frequency operation increases its a...
