Novel Reconfigurable Microstrip Antenna
2008 IEEE Region 10 and the Third international Conference on Industrial and Information Systems, 2008A microstrip square patch antenna is designed and analyzed with re configurability in frequency and polarization. The patch contains two orthogonal slots and two rectangular patches added across the length and width. The diversity in frequency and polarization is achieved through the use of PIN diodes.

Broadband E-shaped microstrip reflectarray antenna with microstrip antenna feed
2015 International Conference on Microwave, Optical and Communication Engineering (ICMOCE), 2015Broadband reflectarray microstrip antenna with an array and feed element consisting of E-shaped patches is proposed. The reflect array configurations namely, 1 × 3, 3 × 1, plus-shaped and 3 × 3 arrays have been studied. A parametric study for varying distances between the fed E-shaped patch and array of E-shaped patches for varying slot dimensions is ...

A broadband microstrip antenna: SGMFP antenna
Microwave and Optical Technology Letters, 2003AbstractA novel structure of broadband microstrip antennas, termed the SGMFP antenna, is proposed. It is consisted of a slot in the ground plane, a microstrip feedline supported on a substrate, a foam layer, and a patch. It can achieve broad bandwidth and high polarisation purity.

Small Square Microstrip Antenna
2010A small shorted square microstrip antenna with air dielectric (e r = 1.001) substrate is presented. The probe fed square microstrip antenna incorporates a single shorting post of radius 0.6mm which significantly reduces the overall size or area by 82% from a conventional square microstrip antenna of same substrate and height.

A multifrequency microstrip antenna
Microwave and Optical Technology Letters, 2005AbstractInvestigations of a microstrip antenna for multifrequency operation are reported. The integral‐equation method, using IE3D software, is used for the analysis of the antenna. The antenna can be used to operate at four different resonance frequencies with broadside radiation patterns.

The sinuous microstrip antenna
Antennas and Propagation Society Symposium 1991 Digest, 2002Multioctave microstrip antennas recently developed by the authors (1990) for a spiral geometry have been extended to a sinuous geometry with good performance over a 5:1 bandwidth. The motivation for using the sinuous configuration is to achieve polarization diversity.

Multifunctional microstrip antennas
1985 Antennas and Propagation Society International Symposium, 2005A microstrip antenna system that is capable of simultaneously transmitting an outgoing circularly polarized wave while receiving an incoming circularly polarized wave using a microstrip patch antenna element and a signal processing network is disclosed. The signal processing system connects the antenna element to a transmitter and receiver and produces
