A circularly polarized single feed microstrip slot antenna has been introduced in this paper as a candidate for use in GPS applications. The slot structure of the proposed antenna has been created on the radiating patch in two steps. At first, a 45 degree rotated square has been etched at the center of the patch, and then a Sierpinski gasket type of the 3rd iteration occupies the resulting slot...

In this paper, two single rectangular patch antennas with a slot are designed and analyzed theoretically from the concept of multi-cavity structure. The theoretical return loss parameters of the antenna electrical characteristics are in good concordance with the advanced design system (ADS) simulation. Two patch antennas with rectangular slot are designed in two different geometries relatively ...

In this paper, a hybrid dual-band cylindrical dielectric resonator antenna with parasitic slot fed by a microstrip line that is suitable for wireless body area network is proposed. In this configuration, the dielectric resonator performs the functions of an effective radiator along with the feeding structure and the slot in the ground plane. By optimizing the structural parameters, the antenna ...

This paper provides experimental and implementation details for various forms of multiple-input multiple-output (MIMO) cube antennas. Slot dipole antennas are used as basic elements of these MIMO antennas. Experimental results show that especially at higher frequencies of various wireless applications the additional loss of the printed antennas increase and therefore implementation of such ante...

Kyungho Chung et al. 379 ABSTRACT⎯A novel reconfigurable microstrip patch antenna with frequency and polarization diversities is proposed. A U-slot is incorporated into a square patch, and a PIN diode is utilized to switch the slot on and off, which realizes the frequency diversity characteristic. The polarization diversities among linear polarization (LP), right-hand circular polarization (RHC...

A novel design of a CPW fed printed monopole antenna for dual polarization applications is proposed in this paper. The monopole is formed of a rectangular patch embedded with a hour-glass shaped slot. In a modified version of the antenna, an additional spiral shaped slot is incorporated in the ground plane. The overall dimensions of the antenna are kept at 40× 40mm. The impedance bandwidth achi...

A bow-tie slot antenna with tapered connection to a 50Ω coplanar waveguide (CPW) feed line is introduced and its dimensional parameters have been studied for wideband operations in the X-band. A set of two element bow-tie slot antennas fed by one CPW is also introduced for wider bandwidth and improved gain. The configuration of one CPW feeding two elements of this antenna is simulated and it ac...

A compact circularly polarized (CP) patch antenna using a composite right/left-handed (CRLH) transmission line (TL) unit-cell is proposed. The CRLH TL unitcell includes a complementary split ring resonator (CSRR) for shunt inductance and a gap loaded with a circularshaped slot for series capacitance. The CSRR can decrease the TM10 mode resonance frequency, thus reducing the electrical size of t...
