IEEE Antennas and Wireless Propagation Letters, 2018
A patch is proposed to stack above a substrate integrated cavity (SIC) backed filtering slot antenna to enhance antenna frequency selectivity. The antenna is composed of a slot radiator backed by an SIC, a stacked patch, and a microstrip feed line.

The tapered microstrip transition with an overlapped coplanar stripline (CPS) as a feeding structure that effectively excited tapered slot antenna (TSA) geometry is proposed. This designed antenna has the merits such as wideband, simple balun feeding network, low profile compact size with fairly good antenna performances (VSWR, gain and radiation ...

IEEE Transactions on Antennas and Propagation, 2019
A single-layered multiple-input multiple-output (MIMO) antenna system is presented for future wireless devices operating at WLAN (2.45 GHz, 5.2 GHz), 4G LTE (2.6 GHz) and 5G (24 GHz, 28 GHz) bands. The design consists of a dual-band four-element monopole

Unidirectional miniaturized slot antennas
2008 IEEE Radio and Wireless Symposium, 2008A technique for designing unidirectional miniaturized slot antennas is presented in this paper. Our approach takes advantage of the simultaneous application of two different techniques used to reduce the lateral dimensions of a shallow cavity-backed slot antenna.

Microwave and Optical Technology Letters, 2000
A meander slot antenna fed by a strip line is proposed. The length of the slot meander antenna is less than one-eighth of the effective wavelength, while the radiation pattern is similar to that of conventional microstrip antennas. The resonant and radiation properties of the proposed antennas have been examined, and good agreement between simulated ...

Concentric annular slot antenna
Proceedings of 2014 Mediterranean Microwave Symposium (MMS2014), 2014This paper focuses primarily on improving the gain of the circular microstrip patch antenna thanks to the presence of two concentric annular slots. The proposed antenna is excited by a coaxial probe and the design was aided by simulation through using CST resonance antenna at 4.38GHz with gain of 10.2dB and 12.1dB without and with slot respectively ...
