This paper presents the design of a fully packaged 60 GHz wideband patch antenna incorporating an air cavity and a fused silica superstrate. Circular polarization (CP) is realized by introducing a diagonal slot at the center of the square patch. By optimizing the patch and the slot dimensions, a high efficiency (>90%) microstrip fed CP antenna with an impedance bandwidth of 24% and a 6 dB axial...

A coplanar waveguide (CPW) fed Ultra Wideband (UWB) slot antenna with reconfigurable rejection bands is presented in this paper. The antenna has a rectangular slot with triangular structure that acts as a tuning stub with CPW feed. The notch band is achieved by inserting a rectangular slot in the ground plane with a length of λ/2. The rejection of the bands 3.1 GHz – 3.9 GHz, 4 GHz–5.3 GHz and ...

Recently, spiral inductors have widely been used instead of resistors in the design of matching circuits to enhance the thermal noise performance of a wireless transceiver. However, such elements usually have low quality factor (Q) and may encounter the self-resonance in microwave-frequency band which permits its use in higher frequencies, and on the other hand, they occupy the large on-chip sp...

Microstrip Patch antennas are very prevalent these days due to various attractive features possessed by them. Coplanar Waveguide (CPW) fed patch antenna has benefits of compact size, ease of fabrication and integration with other monolithic circuits. Moreover, the proposed design is very simple design fed with CPW feed. The proposed antenna performs dual band (1. 5 GHz and 7 GHz) operation with...

A compact and simple design of a CPW-fed planar antenna for wireless sensor network antenna application with a better size reduction is presented. The proposed antenna consists of an inverted  shaped metal patch on a printed circuit board fed by a 50-Ω coplanar waveguide (CPW). The parametric analysis of length and width are made. The designed antenna’s physical dimensions are 32 mm (length) x...

A lumped-element circuit is proposed to model a coplanar waveguide (CPW) interdigital capacitor (IDC). Closed-form expressions suitable for CAD purposes are given for each element in the circuit. The obtained results for the series capacitance are in good agreement with those available in the literature. In addition, the scattering parameters obtained from the circuit model are compared with th...

This paper presents a novel CPW fed patch antenna supporting a wide band from 2.7 GHz – 6.5 GHz. The antenna is compact with size 32 x 30 x 1.6mm, built over FR4-epoxy substrate (εr=4.4). Bandwidth enhancement has been achieved by using the concept of modified ground structure (MGS). For this purpose structural design has been optimized by parametric simulations in CST MWS. The proposed antenna...
