INTRODUCTIONAccidental and unnoticed ingestion of foreign bodies are not very uncommon. Most of such foreign bodies pass through gastrointestinal tract uneventfully and only on rare instances cause obstruction and/or perforation.PRESENTATION OF CASEWe are reporting a case in which a 45 yr old male presented to accident and emergency department of our institute with complaints of pain abdomen, greenish vomiting, abdominal distension, fever and non passage of flatus and stool following alcoholic binge 15 days back. On presentation tachycardia, hypotension, generalised abdominal tenderness and guarding were present. After initial resuscitation and investigation diagnosis of perforation peritonitis was made and emergency exploratory lapratomy was done and a single perforation with plastic foreign body protruding through it was found in jejunum 5 cm distal to duodeno-jejunal junction.DISCUSSIONThe majority of ingested FBs that reach the stomach pass uneventfully through the gastrointestinal tract. The majority of cases occur in children. Only 1% of patient of patients requires surgical intervention depending upon nature, size and shape of the foreign body.CONCLUSIONPresent case report intends to draw the attention towards possibility of intestinal obstruction and perforation by a single plastic foreign body. High index of suspicion is needed as this foreign body is not even radio-opaque and cannot be picked up in X-ray investigations. Also with increasing use of such plastic materials there are increased chances of such incidents.

Abstract-The proposed antenna is a novel structure of stacked micro strip hexagonal patch antenna (SMHPA) operable in 2-6GHz range of frequency with resonant frequencies at 2.8GHz in sub-band 2.78-2.85GHz, 3.98GHz in second sub-band 3.88-4.08GHz and 5.78GHz in third sub-band 5.66-5.95GHz associated with high gains and sufficient return losses. The antenna can be used for WLAN, Wi-Max and mobile-communication. The proposed antenna has been simulated by High frequency structure simulation software (HFSS).
