Bandwidth enhancement of rectangular microstrip patch antenna ... percentage bandwidth increased to 91% with respect to the centre frequency 3.7GHz.the gain of the antenna with two slots is 2.5dB where as for antenna array it is increased to 10dB.The tabular form for VSWR and return loss for both antennas with and without slot is given below. For WLAN parameter 2.4GHz 5.2 GHz 5.8 GHz 2.5 GHz 3.5 GHz 5.5 GHz A NOVEL SLOT FOR ENHANCING THE IMPEDANCE BANDWIDTH AND GAIN ... rectangular microstrip antenna comprising a novel slot for enhancing the impedance bandwidth and gain. By incorporating a slot of optimum geometry at suitable location on the radiating patch, the antenna provides 78.08% (3.39{7.73GHz) of impedance bandwidth and 3dB of gain without changing the nature of broadside radiation BANDWIDTH ENHANCEMENT TECHNIQUES COMPARISON FOR ULTRA ... requirements, various bandwidth enhancement techniques for planar monopole antennas have been developed during last two decades. The recent trends in improving the impedance bandwidth of small antennas can be broadly divided into the following categories the first category is the leading of all categories in numbers and varieties.
Since a conventional microstrip patch antenna is inherently a narrowband radiator, stacked-patch antennas are commonly used either to enhance the bandwidth or to achieve multi-band characteristics. However, the stacked patch structure has a number of geometrical variables which need to be optimized to achieve the desired characteristics.

A Novel Modified Ground Plane Microstrip Patch Antenna for ... rectangular cut, (iii) T slot, which can guide to a good impedance matching. By choosing these parameters, the proposed antenna can be tuned to operate in the (3.1 -10.6) GHz frequency range. Utilization of corner cut approaches has been formerly used to boost the impedance bandwidth for microstrip patch antennas [8-12]. Novel Compact CPW-Fed Antennas with Harmonic Suppression and ... Novel compact CPW-fed antennas with harmonic suppression are presented and investigated in detail. By inserting symmetrical slots connected to the end of CPW transmission line in the ground plane, and exploiting parasitic technique, harmonic suppression, compact size, as well as wide bandwidth are obtained.
