Slot antennas are easier to make and modify, though patch antennas can be nearly as cheaply made using printed circuit board production lines. Slot antennas can send much more powerful signals. You can build a slot antenna into a structure and put it somewhere others may not know it is. The Pros and Cons of Slot Antennas How does a slot effect an antenna’s bandwidth? - Quora Slots are basically used for Bandwidth enhancement and for compactness of antenna. The antenna is designed at some particular resonating frequency which gives some bandwidth then addition of slot overlaps the fundamental mode of antenna and creates higher order mode which overlaps the original bandwidth which gradually increases the overall bandwidth of the antenna. Effects of Square- and Rectangular-Shaped Slots Kept Over ... Abstract. This paper clearly explains the slot loading effects of microstrip antenna. The effect of a series of square-shaped slots of different sizes is studied by using parametric analysis, and radiation characteristics are observed. Effect Of Slot In Microstrip Antenna - TURBO SERVIS NIS
In ref. 30, the design of a broadband printed microstrip antenna for WLAN and WiMAX application was presented, in which two parasitic elements are printed in the ground plane to enhance antenna performance. In ref. 31, a novel dual-band antenna with two U-shaped slots was presented. By using two slots, the dual-band characteristics are obtained.
Slots in patch antenna. U-Slot Microstrip Patch Antenna for Wireless Application | Open Access Journals US6211824B1 - Microstrip patch antenna - Google Patents An integrated directional patch antenna uses multiple patch radiating elements to control the direction of a beam of radio frequency energy (RF) over a large scan volume. The antenna includes a ground plane element and a first dielectric … US4477813A - Microstrip antenna system having nonconductively… A microstrip antenna system having one or more conductively isolated resonantly dimensioned radiator structures disposed less than about one-tenth wavelength above a ground plane is nonconductively coupled to an intermediate layer of … US5287116A - Array antenna generating circularly polarized… A microstrip antenna is disclosed which comprises a ground conductor plate and a patch opposed to the ground conductor plate with a particular distance, a transmission feed line and a reception feed line being disposed between the ground …

This paper presents the effect of the triangular slot square shape microstrip patch antenna. The antenna has 9.37 dB gain at 8.1 GHz and input match of antenna −17.5 dB.
Microstrip Antennas – Part 2 - McMaster University
Variation of E-shaped Microstrip antenna, a broadband rectangular Microstrip antenna cut with three unequal length rectangular slots is proposed. A detail analysis to study the effects of rectangular slots that realizes broader bandwidth is presented.
This paper presents effect of slots on microstrip patch antenna and its parameters. The effect is shown on bandwidth, gain, radiation pattern, return loss, axial ratio and size of an antenna. The slots on the patch or on the ground plane will help to design a ...
