Bhunia,” Effects of Slot Loading on Microstrip Patch Antennas”, International Journal of Wired and Wireless Communications Vol.1, Issue 1, October, 2012 Broadband Microstrip Patch Antenna using Slot etc. It is well known that the major drawback of a microstrip antenna is its narrow bandwidth [2]. One of the popular techniques for broadening the patch antenna bandwidth is to incorporate U-slot on its surface [1]. In this communication [4] a microstrip patch antenna using dual U-slot with broad bandwidth (>37%) is proposed. EFFECTS OF SLOTS ON MICROSTRIP PATCH ANTENNA 2.6. EFFECT OF SLOT ON SIZE OF ANTENNA With the help of slot size of microstrip patch antenna is reduced. This effect can be done by changing the path of current. When slots are cut into patch current is changed. Current travels extra patch as campare to the without slot microstrip patch antenna. 3. Coupling effects of aperture coupled micro strip antenna ...
The subject invention relates to an antenna having broadband characteristics. The antenna is a dual notch device capable of receiving or transmitting electromagnetic waves comprising a substrate, an upper planer conducting antenna element …
A simple square slots loaded unipolar rectangular microstrip antenna is proposed for quad-band operation.In Fig.1 four square slots of equal dimensions are loaded on the radiating patch at distance of 0.2 cm from its horizontal and vertical sides. The Parametric Study and Fine-Tuning of Bow-Tie Slot... A printed Bow-Tie slot antenna with loaded stub is proposed and the effects of changing the dimensions of the slot area, the stub and load sizes are considered inLow profile patch antennas such as microstrip and printed slot antenna meet these requirements.
