There are various Improvement of gain & bandwidth of type of feeding configurations are available some of microstrip antenna them are as, Microstrip line, coaxial probe, aperture The bandwidth & Gain of Microstrip antenna is coupling & proximity coupling. improved by using various type of techniques, which Also these feeding configurations are ... Gain and Bandwidth Enhancement of Rectangular Patch Antenna ... antenna with trapezoidal slot offers a much higher bandwidth (13.15%) in comparison to the conventional rectangular patch antenna (4.2%). Results also show that the gain of the modified antenna is improved w.r.t. the conventional antenna i.e., the gain becomes 3.30 dBi from 1.94 dBi just by varying the dimensions of slot.
Various parameters which include impedance bandwidth, gain, efficiency, radiation pattern, current distribution of the antenna are studied.

Gain and Bandwidth Enhancement of Rectangular Patch Antenna with Trapezoidal Slot for Wi-Max Applications written by Gitansh Gulati, Dheeraj Bhardwaj, Manan Dixit published on 2014/11/24 with reference data and citations Gain enhancement and broadband RCS reduction of a ... Meanwhile, a metasurface composed of an array of rectangular ring unit cells was used for enhancement of the bandwidth of a single-feed circularly polarized antenna. The designed antenna achieved return loss of 36 % and 3-dB AR bandwidth of 28.3 % [15]. Recently, Cao et al. ENHANCEMENT OF BANDWIDTH AND GAIN OF A RECTANGULAR ... The return loss is below −10 dB from 4.45 GHz to 7.4 GHz except at 5.1GHz with a bandwidth of 48%.The antenna is thin and compact which makes it easily portable. A maximum gain of 8.77dB achieved at 4.7 GHz frequency. The VSWR parameter was found to be less than 2 within the operating frequency range. Printed Wide-Slot Antenna Design with Bandwidth and Gain ... An important feature of the proposed antenna design is the stimulus of impedance matching caused by the coupling effects between wide slot and feed length and width. For this reason, the effect of the length , 28.5, 29, 29.5, and 30 mm on the performance of the proposed design is investigated and depicted in Figure 6.
