Patch Loading

Purpose This paper aims to presents the bandwidth enhancement of a hybrid slot–loop antenna using a modified feed structure. Design/methodology/approach The conventional monopole feed of the hybrid slot–loop radiator is loaded with a flat microstrip patch to excite higher-order modes. The proposed antenna combines the resonant modes of the slot antenna, the loop antenna and the patch loading. Findings The antenna exhibits a dual-band response suitable for GSM 1800/1900 and ultrawideband (UWB) standards. The impedance bandwidth extends from 1.65 to 1.95 GHz (11.42 per cent) and 3 to 11.1 GHz (114.9 per cent). The proposed antenna has the smallest footprint with a peak gain of 5.07 dBi at 1.8 GHz and 4.97 dBi at 6 GHz. The prototype antenna is fabricated and the simulation results are validated using experimental measurements. The performance of the bandwidth-enhanced hybrid slot–loop antenna is compared with that of other slot antennas. Originality/value Thus, a hybrid slot–loop antenna with an enhanced bandwidth has been reported in this study. The conventional monopole feed of the antenna is replaced with a monopole ending with a microstrip patch load. The antenna covers the operating bands of GSM 1800/1900 and UWB. The proposed antenna has a smaller footprint compared with other wide-slot antennas reported in the literature.

Radiation Properties

Microstrip patch antennas are printed antennas that find suitability because they are lightweight, low volume, thin in profile, dual frequency, and dual polarization operation, and compatible with MMIC. The objective of chapter is to exhibit the investigations on the bandwidth enhancement of microstrip antennas with special reference to microstrip-line-fed wide-slot antennas. Performances are realized and validated through experimental studies on the impedance properties by VNA and radiation properties by pattern measurement setup. An innovative method for the design of hexagonal wide-slot antenna has been proposed considering it as an equivalent magnetic surface of monopole antenna. Impedance bandwidth of the above slot antenna is enhanced through various tuning stubs. In case of forklike tuning stub, the obtained bandwidth is about 900MHz, for hexagonal stub the available bandwidth is 1751MHz. Further improvement in bandwidth is proposed through rotation of hexagonal wide slot, results in wide bandwidth of 5165 MHz covering all the WLAN and WiMAX applications.
